Network Fiber Connectors

Posted on by

An optical fiber connector terminates the end of an optical fiber. A variety of optical fiber connectors are available. The main differences among the types of connectors are dimensions and methods of mechanical coupling. Generally, organizations standardize on one kind of connector, depending on the equipment that they commonly use, or they standardize per type of fiber (one for MMF, one for SMF). Taking into account all the generations of connectors, about 70 connector types are in use today.

As shown Figure 4-12, the most popular network fiber-optic connectors inclued

● Straight-tip (ST): An older bayonet style connector widely used with multimode fiber, as well as single-mode.
● Subscriber connector (SC): Sometimes referred to as square connector or standard connector. It is a widely adopted LAN and WAN connector that uses a push-pull mechanism to ensure positve insertion. This connector type is used with multimode and single-mode fiber.
● Lucent connector (LC): Sometimes called a little or local connector, it is quickly growing in popularity because of its smaller size. It is used with single-mode fiber and also supports multimode fiber.

Because light typically only travels in one direction over optical fiber, two fibers are usually required to support full-duplex operation. Therefore, fiber-optic patch cables bundle together two optical fiber cables and terminate them with a pair of standard single fiber connectors. Some fiber connectors accept both the transmitting and receiving fibers in a single connector known as a duplex connector, also shown in Figure 4-12.

Fiber Optic Patch Cables are required for interconnecting infrastructure devices. Some of the common patch cords are

● SC-SC multimode patch cord
● LC-LC single-mode patch cord
● ST-LC multimode patch cord
● SC-ST single-mode patch cord

Fiber cables should be protected with a small plastic cap when not in use.

The color of the fiber jacket is often used to distinguish between single-mode and multimode patch cords. This is because of the TIA-598 standard, which recommends the use of yellow jacket for single-mdoe fiber cables and orange (or aqua) for multimode fiber cables.

Fiberstore provide various types of fiber patch cords including single mode, multimode, multi core, and armored versions. You can aslo find fiber optic pigtails and other special patch cables here. For most of them, the SC, ST, FC, LC, MU, MTRJ, E2000, APC/UPC connectors are all available, even we supply MPO/MTP fiber cables.

One of Most Major applications of Optic Fiber—FTTH

Posted on by

FTTH (Fiber To The Home), it is Fiber Optic Patch Cables directly to the home. Specifically, FTTH optical network means (ONU) installed in the home or business user of the user, the optical access network is a series of optical access the user application type except FTTD (fiber to the desktop) closest outside. FTTH technology is characterized by significant not only provides greater bandwidth, but also enhanced network data format, speed, wavelength and protocol transparency, relaxed on the environmental conditions and power requirements, simplifies maintenance and installation.

FTTH advantage

1. FTTH is a passive network, from the central office to the user, fiber optic coupler, fiber optic passive components accounted for most of the equipment, it can be done in the middle basically passive.

2. It is relatively wide bandwidth. Large-scale use is in line with the way long distance carriers.

3. It is a direct bearing on the fiber business, so there is nothing complex issues.

4. Because of its relatively wide bandwidth, support for the agreement is more flexible.

5. With the development of technology, including point to point, 1.25G and FTTH way have developed a relatively complete function.

The optical fiber directly to the user’s home, its bandwidth, wavelength and transmission technology types are no restrictions for the introduction of new services, it is the ideal business transparent network, and it is also the ultimate way to access network development. Although the development of mobile communications at an alarming rate, but because of limited bandwidth, terminal volume can not be too large, the display screen is limited and other factors, it is still pursuing a fixed terminal performance, which is hoped to achieve FTTH. Fiber to the home’s charm lies in its great bandwidth, it is the best solution to solve from the Internet backbone to the user’s desktop bottlenecks.

With the upgrading of technology, greatly reduces the cost of fiber to the home, it will soon be reduced considerably with DSL and HFC networks, which makes it possible for practical FTTH. In China, FTTH is also imperative. From 2011, in China from coastal cities to inland cities, from east to west, opened the curtain FTTH construction. You can say that FTTH is a highlight of optical fiber communication. Accompanied by a corresponding technologies mature and practical, cost closer to ordinary families can afford to reduce the level of FTTH trend is unstoppable.

Furthermore, FTTH technology is still used to solve the “last mile” problem of the information superhighway. FTTH + Ethernet over ADSL (ADSL dial-up time will be established at the highest theoretical 8Mbps download bandwidth, this bandwidth is never changed, but in fact, because the noise detection mechanism ADSL line situation is not good, if it is clearly beginning to establish a connection not reach the theoretical value, may finally be 5Mbps, this bandwidth is also not change.) and ISDN (European popular form of telephone network) transmission speed is much faster.

FTTH has been considered a rising star ultimate ideal access networks, but also broadband development. Because it can meet the diverse needs of various users. Like high-speed communications, home shopping, high-definition television, video on demand and more. The copper wire is the reluctance of the business, it is easy for FTTH. One can imagine, FTTH is to realize telephone, cable TV and Internet “triple play” the best choice.

The Advantages and Disadvantages of Multimode Fiber and Single Mode Fiber Cable

Posted on by

Recently, fiber optic cable becomes more popular in telecommunication because of its great bandwidth, fast speed, long distance transmission and low cost. Single mode fiber and multimode fiber optic cables are important in many networks to transmit optical signals. Though they have the same working principle and functions, each of them has their own advantages and disadvantages.

Multimode and Single Mode Fiber Cable Overview

People who have work experiences with optical networks may be familiar with fiber optic cables. And they may know the basic structure and differences between multimode and single mode fiber optic cable. Here is a simple table showing the basic knowledge of them.

single mode fiber and multimode fiber cable

From the table we can see, multimode fiber cable has a larger core diameter. And it has multiple transmission modes, but they are only suitable for short distance connections. While single mode fiber has a small core diameter, through which only one mode will propagate typically 1310 or 1550nm. Because of that, these cables are often deployed in long distance transmission due to its less dispersion. Following is a direct-viewing picture shows the diameter differences between single mode fiber and multimode fiber cables.

Advantages and Disadvantages of Single Mode fiber Cable

As has mentioned above, single mode fiber optic cable is more suitable for long runs applications when compared with multimode fiber cable. Except for this, single mode fiber cable also has other three advantages.

  • Increase bandwidth capacity.
  • Limited Data Dispersion & External Interference. The single input mode allows SMF to limit light scattering, which in turn reduce light waste and increase data transmission data.
  • Fast Transmission Speed. Single mode fiber cable can support data transmission speed up to 10Gbps.

Each coin has two sides. Single mode fiber cable also has disadvantages. The most one is the cost. Although it has better performance in long runs transmission than multimode fiber cable, single mode fiber cables often cost more.

Advantages and Disadvantages of Multimode fiber Optic Cable

With a larger fiber core and good alignment tolerances, multimode fiber cable and components are less expensive and are easier to work with other optical components like fiber connector and fiber adapter, when compared with single mode fiber cable. In addition, multimode fiber cable also provides high speed and high bandwidth over short distances. And they allows several mode optical signals transmitted at the same time.

However, multimode fiber cable has high dispersion and attenuation rate, the quality of optical signals is reduced as the transmission distance is getting longer. Therefore, multimode fiber cable is often used in data and audio/video applications in LANs.

Owning to their own characteristics, single-mode fiber cable and multimode fiber cable have different application areas. Based on the transmission distance and deployment budget, if the transmission distance is less than 10 miles, the multimode fiber cable is better, for it needs less expensive optical transceiver and other components. And if the distance is over 10 miles, single mode fiber will be needed.
