Understanding Ports of Gigabit PoE Switch

Since the introduce of Power over Ethernet (PoE) technology, PoE LAN switch has become popular among wide users. However, newbies are usually confused with the multiple port configuration on gigabit PoE switch. Since there are already regular PoE Ethernet ports for powered devices (PDs), what are the function of other ports like console port, SFP/SFP+ port and combo port on gigabit PoE switch? This article will take 8 port PoE switch, 24 port PoE switch and 48 port PoE switch as example to illustrate multiple port for your reference.

Console Port on Gigabit PoE Switch

Like regular Ethernet switch, gigabit PoE switch often has one built-in serial console port, say FS S1130-8T2F 8 port PoE switch. It is the port for controlling and managing switch since there are no display device for a switch. Usually console port on gigabit PoE switch is an RJ45 receptacle. To connect a computer directly to the 8 port PoE switch, one should use dedicated rollover cable rather than Ethernet cable for connection.To use console port, you need physical access to the appliance. Therefore for terminals without serial console port, one should attach a corresponding adapter to the devices before cabling.

RJ45 Port vs SFP Port on Gigabit PoE Switch

RJ45 port on gigabit PoE switch is the regular PoE port to achieve data and DC power transmission for PDs. It is an auto-sensing 10/100/1000Mb copper port supporting only Ethernet cable (Cat5e/6/6a/7) for connection. Thus RJ45 port connection is limited to 1G speed and 100m (330ft) short distance transmission. Then how about longer distance transmission scenario?

Different from RJ45 port, SFP port on gigabit PoE switch has the opt of both short and long reach. Why? The mini GBIC port has inherited the compatibility of either copper or optical SFP connection. Provided you employ the corresponding SFP module and cable on power over Ethernet switch. For long distance transmission, you should use fiber SFP modules with fiber patch cable for optical link. For short distance, you can opt to use RJ45 SFP module with copper network cable on gigabit PoE RJ45 switch for electrical link. Gigabit PoE switch often provides 2 SFP port for optical connection or uplink aggregation requirement, which enhances network adaption resiliency of PoE powered switch. For instance, S1400-24T4F 24 port PoE switch has 2 SFP ports reserved, which caters for fiber uplink to upper layer switch.

SFP+ Port on Gigabit PoE Switch

To illustrate SFP+ port on PoE Ethernet switch, we’ll take S1600-48T4S 48 port PoE switch as example. This 48 port PoE gigabit switch comes with 1 console port, 48 PoE+ RJ45 ports and 4 SFP+ ports. The 48 RJ45 ports are PoE ready to power on dozens of VoIP phones, IP cameras and wireless APs. The 4 SFP+ ports on gigabit PoE switch serves as uplink to connect 10G SFP switch for uplink aggregation.

Combo Port on Gigabit PoE Switch

Though manufactures often clearly label combo ports on gigabit PoE switch for identification, many people don’t know its function. Take S1400-24T4F 24 port PoE switch as example, 2 combo ports are reserved on this 24 port PoE managed switch. The combo port compounds RJ45 and SFP front ends in one single interface, thus it supports either copper or optical SFP link. However, you cannot use these two physical accesses on PoE network switch simultaneously. That is, once you activate combo SFP port on gigabit PoE switch, you also disable the opposite copper port.

S1400-24T4F 24 port gigabit PoE switch combo port

Figure 4: A demonstration of combo ports on gigabit PoE switch: S1400-24T4F 24 port PoE switch from FS.COM.

Conclusion

To sum up, multiple ports on gigabit PoE switch owns different functionality, which enhances switching resiliency for different network cabling. RJ45 port on PoE powered switch is an normal one for copper link to PDs. SFP port of gigabit PoE switch provides options of fiber cabling or copper cabling due to fiber SFP module and RJ45 SFP module compatibility. 10G SFP+ port on 48 port PoE switch serves as uplink port for link aggregation in network layer. Combo port compounds RJ45 and SFP interface in one single fabric on gigabit PoE switch. So it helps to extend flexibility of physical access through the network. For 8/24/48 port cheap PoE switch buying, you can find decent offer here with optimal port configuration.

Gigabit PoE Switch vs Normal Switch

The telecommunication industry has always been developing with leaps and bounds and technology changes with each passing day. For common people with few network knowledge, the evolving optional network devices like PoE switch can be a big puzzle. What is PoE? What is the distinction of gigabit PoE switch vs normal switch? Read this article for reference.

What Are PoE and PoE Switch?

PoE, abbreviation of Power over Ethernet, is a technology that enables Ethernet cable to supply power. Thus power sourcing equipment (PSE) can transmit both data and power to powered devices (PD) simultaneously via one single cable. PoE has two standards available on network switch: IEEE 802.3af/at. The former orginal PoE standard is defined in 2003, which provides 15.4 W power budget to PDs (12.95 W available for accessing). The latter PoE+/PoE Plus standard defined in 2009 provides up to 30 W (25.5 W) power.

PoE switch is one of the two types of PSE for PoE implement: endspan switch and midspan PoE injector. To enhance network resiliency, gigabit PoE switches provided by FS.COM are highly compatible IEEE 802.3af/at managed PoE+ switches. For example, S1130-8T2F managed gigabit 8 port PoE switch with 2 SFP ports can connect to gigabit Ethernet network while S1600-48T4S 48 port PoE switch can use the SFP+ ports to connect with 10gbe switch for higher performance data transfer.

S1130-8T2F 8 port PoE switch

Figure 1: FS S1130-8T2F 8 port PoE managed switch can be flexibly placed in a rack, on a wall or on desktop.

PoE Switch vs Normal Switch: What’s the Difference?

In a word, PoE switch and normal switch differ from PoE accessibility. A regular Ethernet switch is not PoE enabled to supply power for end users over Ethernet. Therefore the user requires one extra cable to connect power outlets. However a normal switch can also become PoE ready by employing a midspan injector between the switch and PDs. The injector will add electrical power while receiving data signal from Ethernet switch end cable, and then deliver both data and power to PDs. But in this circumstance the injector also needs a wire for power. When using gigabit PoE switch, only one power cable is required. Then the PDs can be directly plugged into the PoE gigabit switch port for both data transmission and power supply. The illustration and table below list the differences of employing PoE switch vs normal switch while adding PoE to network.

gigabit PoE switch vs normal switch

Figure 2: An illustration of deploying PoE gigabit switch vs normal switch when adding PoE to network.

PoE Switch Normal Switch
Required Accessories Easy for management (power and transmission) Require separate two wires for powering on normal switch and PoE injector
PoE Access Method Upgrade to PoE network by replacing the normal Ethernet switch with PoE Ethernet switch Install PoE injector between switch and PDs to add PoE capability to the existing non-PoE switch
Emergency Reaction Potential chance of the whole system’s outage Only one device be affected
What Are the Advantages of PoE Switch?

As mentioned above, PoE switch differs from normal switch for supplying power to PDs in the meantime of data delivery. Though the normal switch system can also acquire PoE by installing injector, PoE endspan has the superiority of direct Power over Ethernet ability. Counting to this, gigabit PoE switch owns edges over normal switch as follows. First, it enables PDs like IP surveillance cameras to be placed almost anywhere: on the ceiling, concealed in a wall, or even underwater while only one cable is needed to run to them. Second, it saves extra expanse and time for power cabling and injector installation. Third, with simplified cabling of all PDs directly connected to gigabit PoE switch, the data center is easy for management and control. Besides, PoE gigabit switch itself is designed with advanced features like high-performance hardware with software, auto-sensing PoE compatibility, strong network security and environmental adaptability.

Conclusion

Gigabit PoE switch can supply power to PDs in the meantime of data transmission via one single Ethernet cable while normal switch can only send data to them. For PoE implement, normal switch requires a power-on auxiliary injector as midspan between switch and powered devices. Thus PoE switch owns advantages of direct PoE connection, easy and flexible placement, cost-efficiency, simplified management and etc. For any applications of IP surveillance cameras, VoIP phones and wireless APs, PoE switch over normal switch is a good solution to go.

Can 10Gb Switch Port Link to Gigabit Switch Port?

With the tendency for higher speed network, 10Gb switch has already become familiar with home individuals, no longer the privilege of enterprise operators. However, the issue of SFP to SFP+ compatibility always puzzles many network switch users, even some engineers. Will 1Gb SFP transceivers work with 10Gb SFP+ ports on 10Gb switch? Or will 10Gb SFP+ run at 1Gb to link gigabit switch? And If 10Gb optics in a switch can auto-negotiate to 1Gb when the other end is 1Gb? All these related questions origin from the link between 10Gb SFP+ slots on 10Gb switch and 1Gb SFP ports on gigabit switch. Thus this article will reveal the mask of SFP to SFP+ compatibility from this point of view.

10G SFP+ Port on 10Gb Switch Take 1G SFP Optics on Gigabit Switch in Most Situations

Will 1Gb SFP transceivers/modules work with 10Gb SFP+ ports? The answer is “Yes” in most cases. There are many vendors providing 10Gb switches that can take both a 10G SFP+ and a 1G SFP in the 10Gb SFP+ slot, but not at the same time for obvious reasons. This option is supported by dual speed operation. So before plugging a SFP transceiver into the SFP+ port on your 10GbE switch, one must consult your rep to make sure the 10Gb switch port support dual speed.

To achieve link of 10Gb switch port to gigabit switch port, here is a simple guide. Install a 1Gb SFP module on the 10GbE switch SFP+ port and the gigabit switch 1Gb SFP port respectively, then connect the 10Gb switch and the gigabit switch with corresponding 1Gb SFP fiber cable or Ethernet copper cable (eg. Cat6).

1G SFP Port on Gigabit Switch Cannot Take 10Gb SFP+ Optics on 10Gb Switch in All Cases

Will 10Gb SFP+ running at 1Gb? The answer is definitely “No”. SFP optics do work in SFP+ slots in most cases, but SFP+ optics on 10Gb switch can never work in SFP slots on gigabit switch. The reason is about a power availability thing. As we know, once an module is installed, the speed of the port is decided. Most SFP+ slots are backward compatible with SFP modules to run at 1G speed. However, the SFP slots on gigabit switch cannot support the 10G speed required by SFP+ modules. For instance, most Cisco and FS 10Gb switches support 10G SFP+ and 1G SFP optics on their SFP+ ports. But some Brocade gear and HP A-series models are SFP+ only. One need to double check the compatibility of this switch with the vendor rep.

FS 10Gb switch SFP+ port link to gigabit switch SFP port

FS 10Gb switch SFP+ port links to gigabit switch SFP port via 1G SFP modules and fiber patch cable.

SFP+ Optics in a 10Gb Switch Cannot Auto-negotiate Down to 1G when the Other End Is Gigabit Switch

Unlike copper SFP modules supporting 10/100/1000 auto-sensing, fiber optics do not support auto-negotiation. Because this technology is based on electrical pluses but not optical pluses. Thus 10Gb SFP+ optics on 10Gb switch can not auto-negotiate down to 1Gb if the other end is gigabit switch. In fact, most SFP and SFP+ transceivers only run at its rated speed and the transceivers at both end of the cable should at the same speed. For example, if a 10Gb SFP+ module is plugged into the 10Gb switch port, it will only run at 10Gb. In this case if you link it to the gigabit switch port, it will not work. When sticking a 1Gb SFP module in the 10G SFP+ port, the 10Gb switch will only run at 1Gb. As thus you can link it to gigabit switch.

Sometimes the 10GbE switch port would lock the speed at 1G until you reconfigure the switch to 10G. It is noted that SFP+ port usually enables a speed under 1G, which means one cannot insert 100Base SFP modules into SFP+ ports on 10Gb switch.

Conclusion

For the issue of SFP to SFP+ compatibility, a simple response is that most SFP+ can take SFP but not vice versa. The uncertain situation requires one to ask their switch vendors for clear reply. Thus 10Gb switch port is possible to link to gigabit switch port to run at 1G speed. The only thing you need to do is to plug each the aforesaid port with a 1Gb SFP module, and then connect the two modules on the 10Gb switch and the gigabit switch with a corresponding fiber patch cable or Ethernet copper cable.

10Gb Switch for Home

Since the introduction of 10 Gigabit Ethernet, the ever-increasing demand for high bandwidth has been driving the pervasive application of 10Gb Ethernet switch. However, for its high cost it is normally limited to the enterprise and server market and doors are shut down for home individual users. Nevertheless, gamers and speed addicts always hanker for the faster hardware, so the demand for high bandwidth at home provided by 10Gb switch is rising too. Only once attempt to 10GbE, one will never want to turn back to 1 Gigabit Ethernet.

10Gb switch for 10Gb home network

Overview of 10Gb Switch for Home

Generally, there are several versions of 10GbE switch. The first is 1GbE switch with a few 10Gb SFP+ uplinks, such as FS S5800-48F4S 48 port 1GbE SFP switch with 4 10GE SFP+ ports ($1699). The second is 10GbE switch with 10Gbase-T ports or 10GE SFP+ ports as main connection, such as FS S5900-24S 24 10GE SFP+ switch ($1999). Another is 10GbE switch with a few 40/100G QSFP+ uplinks, such as FS N5850-48S6Q 10GbE ToR/Leaf switch with 6 QSFP+ 40GbE ports ($2999). For 10Gb home Ethernet, the former two switches can be taken into consideration for their cheaper price. Especially for the first type, it is very popular for building 10Gb home network. Here are some reasons. First, one can connect the host, virtualized server and workstation with the 10Gb links. Second, 10Gb SFP+ connection usually costs less power and expense than 10Gbase-T switch. Table below lists the most cost-effective 10Gb switches provided by FS.COM.

How One Benefits from 10Gb Switch for Home?

As we know, we can connect 10G NICs directly and interconnect devices with 10Gb SFP+ cables to achieve 10Gb network. Thus many people get confused about one question: why not using cheaper 10G NICs rather than expensive 10Gb switch? For very small 10G network with a few computers, NICs indeed can be a solution. But how about home networks with more users? For instance, you have 4 computers, then you need to buy 8 total 10G NICs and corresponding cables for connection, which can lead to expensive additional cost for expansion. So at this point home users need to think about deploying a 10Gb switch. Moreover, 10Gb switch features low- latency, fewer bottlenecks, simple virtualized environment, spare bandwidth, rack space efficiency, low power consumption and expansion flexibility.

How to Build 10Gb Switch for Home?

To set up a 10Gb home network, several components are required. 10GbE core switch, access switch with 10G uplinks, 10G network interface card (NIC) for storage and server, and 10G cabling. For 10G switch selection for home, maybe you should avoid some brand-name vendors for their high expense. FS specially designed S3800-48T4S 10Gb switch for home users with a low offer at $499 ($479 with single power). It has 48 1000Base-T ports with 4 10GbE SFP+ links. For 10G cabling selection, there are RJ45 copper cable and SFP+ fiber capable of working with 10Gb/s. Usually, home users have no need to switch from Ethernet copper cabling to fiber cabling. But for 10Gb speed, you’d better use Cat6a or Cat7 Ethernet cables to resist interference. And for NACs and severs with 10G SFP+ links, the most cost-effective solution is to use 10G (Direct Attach Cable) DAC. It is a copper cable with SFP connection on each side available for various lengths. For example, FS SFP-10G-DAC, Cisco compatible SFP+ to SFP+ connection, is a passive direct attach copper twinax cable with length ranging from 0.5m to 7m.

How to Add PoE to Your Network?

In data centers, there are a lot of electrical devices and each one requires a power supply cable and at least one connection wire for transmission. It’s a disaster to see all those wires scattering all over the floor and tangling together. To introduce Power over Ethernet technology, we can cut down the number of wire drops and simplify the management control. So what’s the practical methods for adding PoE to your network? Read the following passage, to learn about the two solutions: adopting PoE switch or PoE injector.

Overview of PoE Implement Method

PoE requires PoE-enabled networking devices for power supply on the Ethernet cable. To realize this technology, there are two types of power sourcing equipment (PSE) for adopting: endspan (IEEE 802.3af refers to it as “endpoint”) and midspan. Endspan is an Ethernet switch that has built-in PoE data transmission circuitry. A midspan is an intermediary device between a non-PoE switch and powered devices (PD). Thereinto PoE injector is a frequently used available external midspan device.

Adding PoE by PoE Switch (Endspan)

When you need to set up a new Ethernet network with power over Ethernet technology or you want to upgrade system and replace older non- PoE switches, employing endspan is a good choice. How to add PoE to your network by PoE switch? Just connect it to other network devices, and the switch itself will figure whether they are PoE supportable devices and control power automatically. There are various types of PoE switch available, ranging from “dumb” unmanaged one, smart partly managed one and fully managed one with advanced management. It is also various from port quantity, such as 8, 16, 24 and 48 port.

It is noted that the PoE+ switch is a PoE plus switch for providing up to 30W power consumption. For example, FS S1130-8T2F 8 port PoE switch is a managed PoE+ switch with 2 SFP port, IEEE 802.3at complied and IEEE 802.3af backward compatible. It has maximum power supply of 130W and switching capacity of 20Gbps. FS S1130-8T2F supports various PoE devices and is best fit for network equipment such as wireless APs, IP phones and weather-proof IP cameras.

Adding PoE by PoE Injector (Midspan)

If you don’t want to discard your already used network switch and only PoE capability is needed to be added, you can simply adopt midspans. PoE injector is a device that can add electrical power while receiving signal from one end of the cable, and then deliver both the data signal and the power via the other end of the cable. Instead of PoE switch, midspan can also be used as an economical and functional solution where only a few PoE ports are in demand. How to add PoE to your existing LAN by PoE injector? First, power on PoE injector and non-PoE Ethernet switch respectively, next connect them via an Ethernet cable. Then connect PDs such as IP phones with PoE injector and finally the system can run as a whole.

In the case of older end devices are not PoE-ready, a splitter can be helpful for adding PoE to your network. To apply a splitter onto the end of the Ethernet cable will enable signal and power to be split into two different lines.

PoE switch vs PoE injector installation

This figure shows the installation of PoE switch vs PoE injector for adding PoE to network.

PoE Switch or PoE Injector: Which to Employ?

After diving into each respectively, we made a comparison of PoE switch vs PoE injector for concerning about adding PoE to network.

PoE Switch PoE Injector
Price Higher Cost Economical
Management and Control Easy for management (power and transmission) Requiring separate two wires for powering on switch and PoE injector
Implement Method Upgrade to PoE network by replacing the old Ethernet switch with PoE switch Install PoE injector to add PoE capability to the existing non-PoE switch
Emergency Reaction Potential chance of the whole system’s outage Only one device be affected

For most concerns about cost-efficiency and PoE capability required, you can go for PoE injector. However, for upgrading system and future-proof superior functionality concern, PoE switch is obviously a better choice.

Conclusion

Both PoE switch and PoE injector are power sourcing equipment for adding PoE to a network. PoE switch is an endspan, naturally fitting for new set-up or upgrade-needed network. PoE injector is a midspan, better fitting for existing non-PoE network without switch replacement requirement. For PoE switch purchase, FS.COM is a reliable vendor providing a wide rage of types for different demands. Any other information to know, just visit our official website and blog.

Understanding SFP Ports on SFP Switch

Catching a glance of the modern network devices, one will see different ports are built in for different connection. For instance, we got USB interfaces in cellphones and RJ45 ports in copper switch. But how about SFP port? SFP port is built-in interface in various devices including gigabit switch, SFP switch, network interface card (NIC). This article will focus on the understanding of SFP ports on SFP switch.

What Are SFP Ports on SFP Switch?

SFP port (mini-GBIC port), a small form-factor hot pluggable interface, is designed for high speed and density SFP connection. It is typically built in 10Gb switch with SFP+ uplinks. Different from RJ45 ports for copper connection only, SFP ports on SFP switch support both copper and optical links. When SFP ports on SFP switches are inserted into SFP modules with electrical ports, Ethernet copper cables (Cat5e/Cat6/Cat7) are needed for data transmission. When SFP ports are plugged by SFP optical modules with optical ports, fiber patch cables are required for data transmission. Counting to this feature, SFP ports empower SFP switches the switching function to connect various Ethernet and fiber cables through the network. For the fiber one, single mode fiber (SMF) and multimode fiber (MMF), 1GE and 10 GE speed are all compatible. Moreover, it contributes to the adaptability of either short distance transmission by deploying RJ45 SFP or long distance transmission by fiber SFP.

FS SFP switch

Figure 1: This is a demonstration of SFP ports on FS SFP switch plugged by fiber SFP modules, then connect single mode fibers for data transmission.

SFP Ports Advantages on SFP Switch

·Small Size and Hot-pluggable Feature

Compared with early GBIC module port, SFP port for SFP module has much lower volume ratio. This small-sized optimization enables 2 times the density for SFP ports configuration on the same patch panel. Thus also expands the whole data capacity. Besides, SFP port is an I/O device, which is hot-swappable. Moreover, SFP ports on SFP switches can be exchanged with different port types, such as 1000Base-SX, 1000Base-LX/LH, 1000Base-ZX and 1000BX10-DU.

·High Reliability and Security

Fiber SFP plugged into SFP port on SFP switch usually connects with a fiber cable, which delivers data in light rather than electrical signal. First, for reliability concern, it largely diminished data loss and electromagnetic interference. Second, for security concern, fiber jumpers are less likely to catch on a fire than copper cables in severe environment. Sensitive data information is also more difficult to be illegally filched.

·10 GE SFP+ Uplink for Higher Network Capacity

Gigabit switch often has built-in SFP ports and SFP+ ports. They can support the load blancing of redundant links. Even though currently you only need 1GE network, for the concern of later system upgrade and future-proof technology, 10GE SFP+ ports are necessary for SFP switch.

How to Use SFP Ports on a SFP switch?

To illustrate the usage of SFP ports on a SFP switch, taking FS S5800-48F4S 10gb switch as an example.

Buy Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch

As for the issue of Gigabit network setups for more than 24 connections, we usually stick in the dilemma of choosing from different scenarios of Gigabit switch: deploying 2 x 24 port switch or 1 x 48 port switch, which one to take? We are here to weight their pros and cons for your selection guide.

Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch Overview

Budget is always a big concern before touching other factors. It is somehow a common sense that buying 2 x 24 port switch costs less than a 48 port switch. Thus many people go for 2 x 24 port switch for cost savings. In fact, that’s not always the same case. For example, buying one S3800-48T4S 48 port switch ($499.00) will save you over 200 dollars than two S3800-24T4S 24 port switch ($369.00) from FS.COM. For people pursuing high performance but with tight budget, just go for FS S3800-48T4S 48 port switch, which best satisfies your dual demands.

2 x 24 Port Switch Solution Pros and Cons

For concerning about 2 x 24 port switch solution, one should know its pros and cons. First, having 2 x 24 port switches gives you more sense of security. If one switch goes down, users in another switch will still be running. However the collapse of the sole 48 port switch will lead to the whole network’s breakdown. Second, 2 x 24 port switch solution provides more flexibility for separate placing. If you need to connect different devices in different floors or offices, 2 x 24 port switch is the way to go. However, it is noted that this solution has the cons of higher potential bottleneck, less available ports, extra uplink port demand, space consumption and management inconvenience.

1 x 48 Port Switch Solution Pros and Cons

Apart from the cost-efficiency of 1 x 48 port switch offered by FS.COM, there are other cases 1 x 48 port switch is preferred. First, 48 port switch is natural for high-performance network environments. In 2 x 24 port switch solution, due to one extra uplink port for connecting the 2 switches, a potential bottleneck/congestion is created and only 46 ports are left available for devices. So in cases only one uplink is available, 48 port switch is the choice. Second, 48 port switch has the pros of ease of management and rackspace saving even if 2 x 24 port switches are stacked. Third, one 48 port switch costs less power than the 2 x 24 port switch strategy. However, this solution will lose the redundancy for network outages and separate placing flexibility.

Gigabit Switch: 2 x 24 Port Switch or 1 x 48 Port Switch Selection Guide

After explaining the two solutions respectively, we made the following conclusion. For most concerns about performance, one should go for 1 x 48 port switch, which owns lower potential congestion at the uplink port and can travel at the wire speed. For concerns of space saving, management convenience and more port numbers, also go for the same way. But in terms of redundancy and separate placing, one should better take 2 x 24 port switch.

Table below lists the edges for selecting one solution over the other.

Solution 2 x 24 Port Switch 1 x 48 Port Switch
Edges over the other Redundancy: one more backup switch in network outages High performance: wire speed; power saving; less potential congestion
Separate placing: different floors or offices More available ports: saving extra uplink for connecting two switches
Generally less cost Rackspace saving; Ease of management

In some cases requiring for special conditions, pay attention to their built-in features. For instance, in quiet places such as classrooms, take fanless 24 port switches because 1 x 48 port switch can be noisy due to equipped fan radiator.

Conclusion

For Gigabit switch: 2 x 24 port switch or 1 x 48 port switch, it’s extremism to simply say which one is superior or inferior. We decide which to buy by the factors we are most concerned about and the respective edges over the other in each case. No matter you need 24 port switch or 48 port switch, FS.COM would be a good place to go.

Patch Panel vs Switch: What’s the Difference?

In network setups we see everything is plugged into a switch, but before that fiber cables are also connected to another supply – patch panel. Thus one question is often confusing: patch panel vs switch: What’s the difference and what’s the significant function of them respectively?

What Is Patch Panel?

Patch panel (fiber optic patch panel, fiber optic enclosure) is a terminate unit of network ports centralized together. It is a cable management solution component used to organize fiber cables and keep everything neat for a clean wiring closet. In data centers, a mass of cable wires scattering all over and mixed together can be bothersome, in this case a patch panel is indispensable and rather helpful. It not only offers ease of management, but also protect the terminations from being knocked. Besides the fiber optic patch panel, other cable management accessories including cable ties and cable labels are also used to keep cables tidy and easy for identification.

What Is Switch?

Switch, commonly known as network switch, is an appliance in a data center that connects all devices (such as PCs and servers) as a whole to achieve intercommunication and data sharing between different network devices. It channels the incoming data from multiple input ports to the specific output port so as to deliver the data toward its destination. In Ethernet LAN or WAN, modern network switch usually determines which output port to use by network address.

Role playing Cable management tool:
Centralizing cable wires together; protecting fiber cables from damage.
Functional performance: connecting all devices together to receive and transmit exact messages to the target device end.
Form feature  fiber optic patch panel  network switch
·Role in Date Center

Comparing patch panel vs switch, we can make the following conclusion. Patch panel is nothing but an essential cable management tool, which exerts no functional influence to the performance of data transmission. However, a switch is an irreplaceable functional supply in network setups.

Why Patch Panel Is Commonly Set Up in Network Installation?

As mentioned above, patch panel has no effect on the data transmission process. Can it be omitted in fiber optic cabling? Or can wires just directly plugged to a switch? The answer is yes when you just deal with several fiber cables. However, Ethernet patch panel is a must in data centers where there are a large number of Ethernet drops. No doubt you don’t want to see all the things tangled together. A patch panel in place provide ease management of classification, maintenance, repair, installation and upgrades.

Conclusion

This article gave an brief introduction to patch panel and switch respectively and then discussed the differences between them. Patch panel vs switch : what’s the difference, and why is a patch panel commonly set up in network installation whereas a switch is already used? Can you answer these questions now? Simply put, patch panel is an essential cable management tool whereas network switch is a significant functional supply in data center. Both of them play important role in their respective positions.
