Buy Cisco GLC-SX-MM SFP For Fiber Optic Networks

Using the rise of communication standards. Global companies now come face-to-face utilizing the fact that they have to upgrade their fiber optic network systems. This way, they get to support data transformation in all forms. This is where periphery components like the Cisco GLC-SX-MM Transceivers prove useful.

The GLC-SX-MM is a hot-swappable tool that connects a Gigabit Ethernet interface, as well as the video machine to the main harbour using the multilevel. It is also commonly used between switches, Wireless LAN Controllers, and firewalls. It is a Short Form-Factor Pluggable that works well having a wide selection of services and products, and can be mixed and matched on the port-by-port basis. This makes it quite competent in either simple or extremely complex networking environments. On top of that, the GLC-SX-MM has high end modules that sustain a data-rate of just one.25 Gbps. For multi-mode fibers, which are probably the most commonly installed types in communal settings, it can transmit data as much as 500mm.

SFP transceivers usually come in different models. This allows the consumer to modify and configure the machine in a manner that it gets proper optical reach, either with multi-mode or single-mode optic fiber cables. The four categories of SFP modules would be the SX, that is 850nm, the ZX, which is 1550nm, the LX that is 1310nm and the DWDM. They are typically created using copper cable interfaces, which permit a host device for connecting via unshielded twisted-pair network cable. The CWDM can also be utilized through single optic cables, and they’re 1310/1490 upstream and downstream.

There are several known producers of SFPs and it’s important that you will get to understand these brands, especially Cisco, if you are planning to grow your network. That way, you’re able to acquire the right kind of gear that would complement the body. If you are looking to buy these things, you may to stick to only one manufacturer, so that compatibility issues don’t arise. Despite the generalization of the IEEE standards that made parts more flexible and inter-changeable for diverse networking needs, there’s still minimal be certain that Avaya networking products would work with Netgear and Cisco gadgets. Now, since Cisco is among the pioneering companies and established brands when it comes to network systems with 28 many years of service, customers can be assured that they will automatically work in any network setup and that in-house engineers will know how to configure them to stabilize the linkages.

When buying Cisco SFP transceivers and supporting network tools, it’s possible to expect costly investments because these are not equipped cheap. However, with thorough research, it is possible for an organization to obtain fair prices for their purchases. It is essential, though, they get expert consultancy first, before any transaction is made. This approach, the specified outcomes are insured, and delays, as well as excess expenses won’t be realized. The Internet provides expansive info on network systems, as well as reliable retailers of networking accessories. Thus, you won’t need to break a sweat in searching for those exact pieces you need.

Keep up with the Development in Networks Nowadays

You aren’t by yourself if you have difficulty keeping up with today’s development in networks. There appears to be considered a lot of ruckus over things to get, when you should have it and why. Allow me to assist you to.

The greatest method to transmit data nowadays is with light-based fiber optics instead of the ancient form of electronic signals and the two greatest modules with this would be the SFP and XFP modules, which are a symbol of small form factor placable with X standing for 10 gigabyte. These modules were formed to bring you greater quality from your signal. Additionally, it’s an economical method of providing changeable gigabyte ethernet fiber optic interfaces to switches and hubs that are equipped with a stock SFP slot.

Finding a trusted retailer, and fully knowing optical transceiver modules is going to be helpful when it comes time to create you buy the car. You will have networking questions and concerns. Therefore finding an experienced fiber networking vendor will be crucial. You will have to have the data possible to make a good choice when choosing manufacturers as well as their modules.

Superior optical fibers transport waves of information sent by optical transceiver modules. Modules transport and receive optical signals. Underneath the Multi-Source Agreement, these form factors are made by companies. Specific standards must be met in their building. Transfer speeds are what exactly are accustomed to classify optical transceivers together. Each supports rates from 1Gbps to 10Gbps. Module factors are referred to as SFP and GBIC are 1Gbps. These form factors support transmissions larger than 4Gbps right down to 100mbps. Modules are known as XENPAK, XFP, X2 and SFP support speeds of up to 10Gbps transportation.

10G XENPAK modules are the widest in 10G transceiver interfaces and can include a dual SC fiber interface. Cisco SFP modules can be found in multi-mode and single-mode optical fiber wire, as well as operating in copper wire. 15 meters may be the normal transmission length of a copper module. 300 meters be the transmission reach of multimode lines.

10G XFP transceivers are equipped for 10G network applications, including 10G Ethernet. The conventional for developing these was made by some of the leading manufacturers in the field. Straightforward to care for and change. They’re also small hot plug-hole. This module is utilized in conjunction with laser multimode fibers.

Optical networking solutions are definitely an industry that is constantly on the expand and grow. Their email list above is only a sum of the optical options that you may have to choose from. Once again, choosing the best distributor will be just like crucial as your education of optical transceivers, and how they work. A vendor who sells a broad selection of optical interfaces is going to be helpful. It’s critical they at least have a background experience in all kinds of fiber optical products. This is really crucial if you’re not an expert yourself.

Before you start to play with your new gadget you could try to buy a fiber optic tester to ensure all is in working order and that nothing has been all messed up because of debris or oil. A 20km distance tests are most popular, but try a patch cord if you’re in a bind. Lucent connectors or LC connectors are the resulting fiber ports to connect to the optical modules. Remember, look at and clean the fiber connector prior to plugging in; they cannot work if blocked with even a small piece of debris.

The Evolution and Trends Of Fiber Optic Transceiver

When it comes to fiber optic transceiver, we can easily think of a lot of different package formats like 1X9, GBIC, SFF, SFP, etc. 1X9 package optical module was first produced in 1999, with SC head, is fixed optical transceiver products, usually directly solidified on the circuit board of communication equipment, used as a fixed optical module. Then, 1X9 package optical module was gradually developed towards miniaturization and hot-pluggable.

Fiber Optic Transceiver

Fiber optical module products began to develop in two aspects. One is hot-pluggable optical module, which became GBIC. The other is small, with LC head, directly solidified to the circuit board, which became SFF 2X5, or SFF 2X10. Both GBIC and SFF optical modules have been widely used.

GBIC Fiber Optic Transceiver

GBIC module, once widely used in switches, routers and other network products. The old Cisco and other vendors’ switched and routers have been widely adopted GBIC modules. Compared with 1X9, GBIC has obvious advantages, hot-pluggable feature makes GBIC can used as an independent module, users can easily maintain, update fiber optic transceiver and fault location. However, with the continuous development of network, GBIC module’s shortcomings also gradually appeared. The main disadvantage is its large size, resulting in a smaller density of service boards, boards can not accommodate a sufficient number of GBIC, unable to adapt to the trend of rapid development of network.

SFF Fiber Optic Transceiver

SFF module, is another branch of fiber optic modules’ evolution, now is widely used in EPON system. In the EPON ONU system, all adopt SFF module. The main reason why ONU use SFF optical module is EPON ONU products are usually placed in the users, require fixed rather than hot-pluggabe. With the rapid development of EPON technology, SFF market is gradually expanding.

SFP Fiber Optic Transceiver

SFP is the latest fiber optic transceiver, also is the most widely used module currently. SFP module is hot-pluggabe (like GBIC) and small (like SFF). Using LC head, and its size is small as 1/2 to 1/3 as that of GBIC Module, which greatly increases the port density of network device, adaptable to the trend of the rapid development of the network, so it has been the most widely used. Currently the main equipment manufacturers, without exception, no one abandoned GBIC products and only produce SFP transceiver. Thanks to the centralized standards, SFP modules from different manufacturers can be compatible with each other, SFP is available as a stand-alone network equipment.

According to the rate, fiber optic transceiver can be divided into 100Base, 1000Base (Gigabit) and 10GE for Ethernet, 155M, 622M, 2.5G and 10G for SDH, which all have been widely used, and now the rate of 40G and 100G has appeared. The 10G modules are widely used in the main transmission, mainly include XENPAK, X2, XFP and 10G SFP+.

XENPAK Fiber Optic Transceiver

XENPAK module is an important step in the evolution. XENPAK in architecture for media access controller provides a XAUI interface. Serializer / deserializer to 10 Gbps available payload and forward error correction overhead assigned to the interface 4 channels, each one line signaling rate decreased to 3.125 Gbps. Compared with non-hot-pluggable, XENPAK module is very attractive, but it can not meet the demand of some important market. XENPAK power is typically 10W, caused a certain influence on the structure of size. Because it increases the printed circuit board manufacturing costs and reduce valuable trace space.

X2 Fiber Optic Transceiver

X2 transceiver also uses electrical interface(like XENPAK), but there are a few exceptions. X2 provides a 4-bit port address space, a bit less than XENPAK. X2 also reduces the number of power pins, and the bottom plate and electrical grounding utilities. X2 retained the 4 vendor-specific pin as Xenpak. In optical technology, X2 supports 10GbE, OC192 SONET, 10GFC and other standards.

XFP Fiber Optic Transceiver

XFP (10 Gb small form factor pluggable module), it provides a architecture with its four-channel interface different from XENPAK. XFP is a single-channel serial module using a XFI (10 Gb Serial Interface) connection at full speed, can replace XENPAK and its derived products. Without serializer / deserializer, XFP is smaller, cheaper and less power consumption.

SFP+ Fiber Optic Transceiver

SFP+ module is smaller than XFP, the circuit for clock and data recovery is transferred to the card from the chip. SFP+ module compressed size and power consumption through putting the CDR and electronic dispersion compensation outside the module.

No matter how fiber optical module develops, it has its own direction. Currently fiber optical transceiver mainly toward the directions of miniaturization, low cost, low power, high speed, long distance and hot pluggable.

Cisco Leads 100G Ethernet Switch Market

In first quarter of 2013, the worldwide Ethernet switch market was $ 4.7 billion, decreased by 8% compared with 2012Q4, but an increase of 1%. 40G is the only port shipment growth products, an increase of 2%, which was mainly due to 40G fixed switches (such as 16xQSFP+) and chassis-based switches 40G line cards. Cisco is the early leader in 100G Ethernet switch port.

Due to the influence of seasonal factors, in first quarter of 2013, the Ethernet switch sales fell, but the past three quarters, the overall is still increased, taking into account the continued weakness in Europe and the U.S. federal government expense decreased , this is a positive signal.

In first quarter of 2013, port shipments fell 4%. 10G, which is generally considered as a star product, the chain fell highest.

40G is the only port shipment growth products, an increase of 2%, which was mainly due to 40G fixed switches (such as 16xQSFP +) and chassis-based switches 40G line cards.

Almost all of the Ethernet switch equipment manufacturers on a quarter-on-quarter drop.

Cisco is the early leader in 100G Ethernet switch port.

Digging Deeper into Pluggable SFP Module

A compact hot plug fiber optic transceiver, the Small Form-Factor pluggable SFP module is used in fiber optic communications for telecommunication and data communications applications. SFP is the interface between a network device mother board and a fiber optic or copper cable network cable.

sfp module

The SFP module is able to support Gigabit Ethernet, fiber channel, SONET, and a number of other communications standards. For your information that in the near future, SFP will expand to the SFP+. At the time, the data rate in 10 Gbit/s is a chievable, including 8 billion fiber channel. Compared to Xenpack or XFP type of modules, all of their circuitry inside, an SFP+ module leaves some of its circuitry to be implemented on the host board.

There is a huge change in the optical transciever is a vailable, each with different transmitter or receiver. This allows the user configure and customize the transceiver to get the proper optical reach with either a multimode fiber or single mode fiber type. In addition, the optical SFP module comes in four categories -SX, which is 850nm, LX, which is 1310nm, ZX, which is 1550nm and DWDM. All of them have an interface of a copper cable which permits a mother board to communicate via USTP (unshielded twisted-pair) cable network. There are also a coarse wavelength division multiplexing and two-way optical fiber cable, single mode 1310/1490 nm upsteam and downstream.

Actually available, the SFP module has the capability transfer rates of up to 4.25 Gbit/s. XFP, a form factor which is virtually identical to the SFP type, increases this amount by nearly three times, at 10Gbit/s. The SFP transceiver is specified and made compatible via a multi-source agreement (MSA) between manufacturers, so that different users who may use equipment from different manufacturers and provides can work effectively and smoothly without worrying about errors and inconveniences.

The GBIC interface is the precursor to the SFP, hence it’s nicknamed as mini gbic. However, the SFP module allows greater port density (number of transceivers per inch along the edge of a mother board) than the GBIC. Also exist the identical Small Form-Factor (SFF) transceiver which is about similar size as the SFP. Rather than plugged into an edge-card socket, it is directly attached to the mother board as a pin through-hole device.

Digital optical monitoring (DOM) or digital diagnostics monitoring (DOM) funcations are supported by the modern optical SFP transceiver according to the industry specifications of the SFP-8472 MSA. The user has the ability to constantly monitor real-time parameters of the SFP, such as optical input/outp power, supply voltage and laser bias current because of this feature.

That have been said, I’m very glad to know that optical transceiver is a very popular format, it is recommended to use a considerable amount of fiber optic component suppliers. These companies carry SFP transceivers for all Cisco devices together with transceiver modules for many other manufacturers. So, if you need technology solutions for your networking applications, you now know what to look for.

How To Save Your Money On SFP Transceivers

Outfitting servers, all new SFP transceiver can be wind up costing a company a few thousand dollars, but investment is necessary, becaused these products provided by the reliability and effective means of communication. Most companies in the market for new modules tend to search online or call a businessman help equip their computer products. Rather than call a dealer or visit a random middlemen, you should check your buying process, where you can save the replacement equipment outside of the OEM or custom objects in order to save cost.

Choose SFP Transceiver Compatible Alternative

Purchasing SFP transceiver from an OEM can cost 50-100 dollars more than you would like, but manufacturers that sell similar items tend to cost much less and manage to come with the same type of facets. Instead of SFP transceivers to help save a ton of money, because they can do everything, why wouldn’t you want to buy these items? For a company looking to lessen its bottom line, why not think about these alternatives to help minimize the costs and go around dealing with the OEM for the product you need.

Buy Used SFP Transceiver

Some individuals cringe when they hear the products is “used” and believe that an old module tends to not have as much value and life as a new module, but ignore this common myth. For instance, you might buy a Cisco GLC-T module at a used price, but the Cisco brand is regarded for its reliability and features that will not break down after a few months of use. With suppliers provide extended warranties on these items and left the orginal cost discount interest rate 50%, than looks diffcult, anyone want to refuse to bargain, are provided here.

Buy a Warranty

Well, so the theme of the article is to help people find ways to save money on modules, but the warranty is to invest later road will also clearly the dividend to investors. Okay, so say you end up with the newest Cisco compatible sfp transceiver for your systems, but some of them break down after a year because of a ruined lens.

You’ve gone past your manufacturer warranty and now you have to spend an extra 300-500 dollars for a replacement. Now, if you would have spent the extra money on a warranty, you could have been spared the hassle of throwing away those three hundred dollars. A warranty is only insrance, but it is always an extra motivation, help you save a large sum of cash if one day, you need it.

FiberStore focus on providing high quality fiber optic cable, Cisco GLC-T, Cisco compatible SFP modules, mini gbic, and related products for local and wide area networking products.

The Data Center Infrastructure of 40G and 100G

Once the server upgrade, top of rack switch uplink require a higher speed. However, during the transition from 1G to 10G full of frustrations. In the past, server vendors comes 1GbE RJ-45 LAN-on-motherboard is free of charge. But now a dual-port 10GBASE-T expensive. Cat5e is almost free, Interconnect never in the past is not a serious cost problem, and now it is. The server companies sale 10G ports, can be mounted on pluggable “daughter card”, cut off the posterior of the subsequent market competitiors and monopoly high prices. Daughter card can and 1G 10GBASE-T, 2-4 SFP+ port and dual-port QSFP combination. With 100G CXP and CFP /2 will be collocation is used. Due to server company in 10G/40G upgrades made a large sums of money, we will ask such a question: “server company will return to the LOM mode, buyers will not need to pay?” Our answer: Yes. But just before the transition to 40G! 10GBASE-T has a problem in high power consumption, size and cost, therefore, when the market of the 10GBASE-T in the development of 28-nm version, so that the SFP+ DAC take advantage. This makes the entire industry landscape has changed greatly. DAC also has its problems. Because it is electrically connected to two different systems, not all of the SFP+ port is the same.

The server-switch link update from 1G to 10G, and the switch uplink increased to 40G, TOR (Top of Rack) switch to connect to the EOR (End of Row) switch until the aggregation switching layer. Data center operators just the economic gloom stood up, still tight budget. “Incremental upgrade” is the investment strategy of the operators. Increase “necessary” 10G/40G link is the current investment. 100G seems to be the exhibition and media attention, but 40G is to make money in the next 2-3 years. Data center began to need 4 ~ 6g, not even to 10G. Therefore, many data center is still in excess, will need to upgrade “. Google, Facebook, Microsoft and other so-called $ 1 billion super data center so that people stare, but they do not represent the mainstream of the data center.

To chase fiber transceiver opportunities, multiple transceiver suppliers is the first to provide less than 50 meters transmission distance of 40G QSFP SR transceiver and Ethernet AOC. 40G QSFP MSA blessed with multi-mode fiber can support short-range (SR) – 100 meters, with the dual-core single-mode fiber with 10km-all in the same QSFP switch port can support. QSFP can plug 36-44 ports per line card, while the CFP can only be inserted 2 in 32W. Although it is very popular in the telecommunications, but not in data communication! OEM prices ranging from $2000 to $3000, it depending on the needs of the data center or telecommunications.

The urgent need for the data center to support tens of thousands of 100G medium transmission link length from the information explosion in demand. Industry conference clamoring. These flow requirements from server virtualization, big data, smart phones, tablet PCs and even software defined network (SDN). Large core switch companies mainly 10-Channel CXP for multi-mode, working together with the transceiver and the AOC. In 4x25G the 25G transmission, multi-mode noise spikes may pose a threat to the multimode transceiver down to 25-50 meters FEC and / or equalization may be required to reach 125 meters. This will make 25-125 meters away from the transceiver higher prices. With 2km Single mode Fiber Optic Transceiverprices narrowed.

At present, the transmission distance of 100m – 600m, there is no economically feasible 100G solutions (unless it can be described with two 40G and 10G transceivers). When the data center becomes greater, which is a hot spot, the IEEE focus of debate. Each additional add 1m, causes the transceiver OEM Price from CXP $ 1,000 he went to the telecentres CFP $ 16,000! Usually claimed transmission 2 km, in fact, can only transmit 400-600 meters, in a loss of data center environments, patch panel and dirty connector can only get 4-5 dB, 10 km link you need to 6dB. Next-generation lasers and instead of SiGe CMOS electronic devices are being developed, but, CMOS electronic harder to develop.

The 40G and 100G are two main data center “form”. Short-range transceiver (SR4), the use of multimode optical fiber can transmit about 100 meters. Using single-mode fiber can transmit 100 meters to 10 kilometers long range transceiver (LR4). This so-called, no formal terminology NR4 aspirations 2km 4dB. SR transceivers typically used to connect a computer cluster and switch layer in the data center. SR transceiver and OM4 fiber combination, can transmit about 300 meters. 125-200 meters, the conversion using single-mode fiber, transceivers and fiber can bring benefit return; even in 25G transmission, also can bring benefits.

The 40G usually in the QSFP or QSFP MSA, usually in four of the 10G channels laying. SR transceiver uses eight multimode fiber (corresponding to one direction), VCSEL lasers and QSFP MSA. LR transceiver uses edge-emitting lasers, multiplex four 10G channels to two single-mode fiber, the single-mode fiber in the transmission of the CFP module MSA 10km, soon also be reached in 28 CFP / 2 and QSFP MSA on this distance. 40G, SR4 and LR4 can be used for the same QSFP switch interface, no problem – just plug in, you can run – you can reach one meter -10 km without any problems. (But still does not work in the 100G)

The 100G SR10 use 20 multimode fiber, VCSELs and CXP MSA. 100G LR4 CFP and two single-mode fiber. Though he promised transmission 100 meters, but the SR10 CXP transceiver typically used to connect large-scale aggregation and core switches from less than 50 meters, when the distance becomes longer, the more than 20-mode fiber will be very expensive, because the multi-mode the optical fiber is about 3 times more expensive than the single-mode fiber. Only in 2012, a number of transceiver companies have announced the development of the CXP 100G SR transceiver. The the 40G QSFP transceiver and the AOCs since 2008 come out. Later on, 4x25G QSFP SR transceiver may to appear CXP transceiver market 10x10G.

Digital Optical Video Fiber Optical Transceiver in Highway Monitoring System

Nowadays there are 3 grades in highway toll stations, toll station, sub-center and center. It seems a separation structure, but it is high efficient centralized management. All the charge stations are far away from monitoring center, and the monitor and control system need to upload images, so point to point fiber transceiver for image transmission is not an ideal, the highway toll station applied the multi-channel video image transmission in the form of transport nodes machine cascade that both N toll station through the video matrix switch out of 2 (or 3, 4) video images through video nodes by 1 core fiber optical transceiver cascade transmitted to the monitoring center. At the same time, the toll station monitoring (holder, lens, matrix switch, etc.) reverse control data transmission by the charging station to provide a data channel.

Highway video transmission system’s main purpose is to put the front end of the video signal and control signal transmission adopts optical transceiver system to road management center. For example, XFP and X2 module.

The section of monitor sub-center monitoring information on a particular road, video signals including road surface monitoring, the monitoring and controlling of the tunnel. Road surface monitoring mainly in entrances and exits, road crowded area and accident-prone area.Tunnel monitoring object is inside the tunnel and the driveway, portal, sidetracked and channel distribution.

And the character of the image inside the tunnel is very scattered and concentrated, Image is dispersion and concentration, perhaps only every a few hundreds of meters will come out tunnel road images, and a few kilometers of tunnels can be up to hundreds of images, each image distance between 120 meters to 150 meters or so.

Road surface monitoring image is more complexed. To fully monitor sections are at intervals of about 2 km image all the way, what the characteristic of this is more scattered.

Because these images will directly reflect each point on the road of actual traffic conditions, monitoring sections of sub-center was required to put forward the fiber optic transceiver system. Generally we should use digital real-time image compression, and optical transmission of optical transceiver become our first choice.

The application of digital video optical transceiver has improved the efficiency of the toll booths, convenient for different toll station business data transmission, and the centralized management of different data.

The world in the future is a digital world. On the way to the digital world, Digital video optical transceiver in the security industry is already very mature. There are more than one hundred optical terminal vendors in the world to provide optical transceivers. FS.COM is a professional optical transceivers company, provide high quality service. We avoid vicious competition, build and manage our own brand, providing customers with better products and services, let the light end factory can better development. For more information about us, please visit our website or contact with our customer service.

The Principle of Buying Fiber Optic Transceiver

In the actual purchase, the enterprise considered an important factor is the price, especially small and medium-sized enterprises and SOHO office. We believe that a few hundred dollars, sufficient to meet the general needs of enterprises, except for special industries, such as telecommunications, military. Of course, in addition to price, but also must consider the compatibility of the product with the surrounding environment in line with and the product itself, stability, reliability, otherwise the low price and then bought useless. In order to be able to pick a good fiber optic transceiver to purchase points listed below:

1. Take a look at itself whether to support full-duplex and half-duplex, because some chips on the market, only to use full-duplex environment, can not support half-duplex, if then switch to other brands (N-Way Switch) or HUB, using a half-duplex mode, will cause a serious colision and packet loos.

2. Take a look at the connection test whether it be done with other fiber optic connectors, fiber transceiver currently on the market is more and more, such as the mutual compatibility of different brands transceiver test did not do it in advance will also have packet loss, transmission time is too long, unsteadiness.

3. Take a look at whether it is to prevent the loos of safety devices, because many manufacturers in the production of fiber optic transceivers, in order to reduce costs, often using the data transfer mode register, the biggest drawback of this way, the data transfer will be unstable, resulting in the loss, and the best way is to use a buffer circuit design, safe to avoid data loss.

4. To see whether the product has to do temperature tests because fiber optic transceivers will produce high fever, coupled with its installation environment usually outdoors, so the temperature is too high (can not be greater than 50°C), fiber optic transceivers whether normal operation, the user is very important factor to consider! The maximum allowable working temperature is how much? Equipment for one to need long-term running this very worthy of our attention!

5. To see whether the product in accordance with IEEE802.3 standard? The fiber-optic transceivers, such as to comply with the IEEE802.3 standard, if you do not meet the standards, then certainly there is a compatibility problem.

6. Weigh the manufacturer’s service Imagine, if your equipment is broken, the factory a few days did not solve the problem, your loss is much ah? Therefore, in order to make the after-sales service timely early response, suggest that you select when the region with superb strong technical force, reputable professional company. Only rich experience in troubleshooting professional technical engineers, more advanced tools of detection failure!

7. The purchase carefully observe the appearance of the product, and the fiber module housing has old, whether shiny or has signs of wear. In today’s market, many vendors in order to reap huge profits, used in fiber optic transceiver, optical switches and other equipment used or old fiber module used fiber optic module, caused a great deal of hidden network transmission, such as: optical fiber the optical path of the module to be contaminated on the signal transmission must be affected by a decline in the quality of transmission. The transmission quality drops, on the reception sensitivity also cause reduced, can also cause data loss phenomenon. Plus the fiber module used in the service life will be compromised at any time parts failure.

Fiber Optic Transceiver Notes

Fiber optic transceivers have a variety of different classification, while most of the actual use note the distinction between the categories according to different fiber optic connectors: SC connector fiber optic transceivers and FC / ST connector fiber optic transceiver.

Connect different devices using fiber optic transceivers, must pay attention to the use of the port.

1. Fiber optic transceiver connection to 100BASE-TX devices (switches, hubs):

Verify that the maximum length of twisted pair does not exceed 100 meters;

To the fiber-optic transceiver connected to one end of the twisted pair RJ-45 port (Uplink port), the other end of the RJ-45 port 100BASE-TX set (switches, hubs) (general population).

2. Fiber optic transceiver connection to 100BASE-TX device (NIC):

Verify that the maximum length of twisted pair does not exceed 100 meters;

Connect one end of the twisted pair to fiber optic transceiver RJ-45 port (100BASE-TX port), and the other end to the RJ-45 port of the network card.

3. Fiber optic transceiver connected to 100BASE-FX:

Recognized that the fiber does not exceed the length of the distance range of the equipment can provide;

SC / ST connector 100BASE-FX fiber connect one end of the fiber optic transceivers SC / FC / ST connector, connect the other end equipment.

Also need to add a lot of users in the use of optical transceivers that: as long as the length of the optical fiber in the single-mode fiber or multimode fiber can support a maximum distance you can normally use. In fact, this is a wrong perception, this understanding is correct only when connected devices are full-duplex devices, when there are half-duplex devices, optical fiber transmission distance there is a certain limit.

The Features And Remarks With Gigabit Interface Converter(GBIC)

GBIC transceiver is short name for the Gigabit Interface Converter, it is a media conversion device between Gigabit Ethernet and fiber optic networks, From this single device, connections can be made using single- or multi-mode fiber optic ports as well as copper wiring. It is possible to benefit from it in many point-to-point communications applications that involve interconnecting components and exchanging data between Ethernet and fiber optic networks. Via the GBIC transceiver, Gigabit network equipment can directly connect to copper wires, single mode fiber ports or multimode fiber ports.

Features:

The GBIC design can be used for hot-swap. GBIC is interchangeable products meet international standards.
