How to Choose the Right PoE Cabling

Power over Ethernet (PoE) is a technology that enables electrical current to be transmitted over standard Ethernet network cables rather than traditional power cords. By operating power and data transmission over a single Ethernet cable, PoE has achieved popularization in a variety of applications, such as IP cameras, IP phones and Wireless Access Points. However, if there is no right PoE cabling, PoE can encounter cable heating and connectivity issues which will adversely affect the transmission performance from PoE switch to these devices and in reverse. So in this article, we will discuss some considerable factors and FS product recommendations related with PoE cabling.

PoE technology applications-PoE switch connecting to IP phones, APs and IP cameras by Ethernet cable

Figure1: PoE technology applications—PoE switch connecting to IP phones, APs and IP cameras by Ethernet cable

Importance of the Right PoE Cabling

Heat generation in cable bundles is one of the biggest issues that affect PoE performance. When power is added to balanced twisted-pair cabling, the copper conductors generate heat and then temperature rises. In the meanwhile, high temperature will bring about higher insertion loss and shorten permissible cable lengths in result. Due to more power dissipation in cabling, bit error rate and power costs increase consecutively. A proper and right PoE cabling with PoE switch becomes especially crucial to the network quality and reliability.

Cabling Considerations for PoE Switch

According to the above introduction, we have known the importance of right PoE cabling. Now, some cabling considerations with PoE switch are suggested to help lower cabling temperature.

  • Category Cabling

Higher category-rated cable typically means larger gauge size. When power currents increase, these larger conductors can perform better than smaller cable. For instance, with larger gauge size, Cat6a can reduce resistance and keep power waste to a minimum degree as it has a lower temperature increase compared to smaller gauge Cat5e. This advantageous performance will create additional flexibility with larger bundle sizes, closed installation conditions and higher ambient temperatures.

  • Cable Structure

Copper cable can be divided into UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cable based on cable structure. Cables with metallic or foil shields, like STP cables are proved to dissipate more heats than UTP (Unshielded Twisted Paired) cables. If possible, choosing a Cat6a STP cable with a foil shield around each pair which can dissipate more heats than Cat5e UTP cable.

  • Installation Configuration

Cables plugged into PoE switch in the middle of the bundle always heat up more than those toward the outer layer of the bundle since they have difficulty in radiating heat out into the environment. Therefore, separating large cable bundles into smaller ones or avoiding tight bundles will help reduce temperature rise. On the other hand, enclosed conduit can contribute to heat issue. To use ventilated cable trays would get better airflow.

FS PoE Switches & Ethernet Cables Solution

When it comes to PoE cabling, we will need PoE gigabit switch and Ethernet cables to construct a network. For PoE switch, FS offers fully managed PoE switches with SFP/SFP+ ports, which deliver robust performance for increasing networks. The details of FS PoE switches are listed as below.

PoE Switch vs PoE+ Switch: How to Choose?

Power over Ethernet, or PoE, is a time-saving and money-saving technology that distributes power and data safely over an Ethernet cable to a targeted network or device. In the current market, if you take notice of switch types, you will find that there are PoE switch and also PoE+ switch. But what are their distinctions? How much do you know about them? In this article we have rounded up some knowledge to help you better understand PoE switch, PoE+ switch and their respective benefits according to different applications.

PoE vs PoE+ Technology

PoE was firstly defined in IEEE802.3af standard and upgraded to IEEE802.3at which is known as PoE+. PoE switches utilize PoE standard that can supply a maximum of 15.4 watts of DC power per port. While IEEE802.3at increases the maximum amount of power to 30 watts. However, some power will be lost over the length of cable. The minimum guaranteed power available at the PD (powered device) is 12.95 watts per port for PoE and 25.5 watts per port for PoE+.

  • Can PoE Devices Work Over PoE+ Ports, or Vice Versa?

The PoE+ standard provides support for legacy PoE devices, meaning that an IEEE802.3af powered device (PD) can operate regularly when connected to IEEE802.3at (PoE+) power sourcing equipment (PSE). But PoE+ PDs require more power than PoE PSEs can provide, PoE PSEs can only supply power to PoE PDs in consequence.

PoE vs PoE+ Technology

PoE Switch vs PoE+ Switch: What Is the Difference?

The main difference between PoE switch and PoE+ switch lies on the electrical power that each can carry or supply to the connected devices. PoE+ PSEs can provide almost twice as much power than PoE PSEs over the Cat5 cabling. The Max. power consumption of PoE switch is smaller than that of PoE+ switches. What is more, PoE+ power sourcing equipment provides 42.5 to 57 Vdc– an increased and much tightened range compared to 37 to 57 Vdc for PoE. Below is the detailed differences between PoE switch and PoE+ switch.

Attribute PoE PoE+
Standard IEEE802.3af IEEE802.3at
Max. Power to PD 12.95 Watts 25.50 Watts
Max. Power Delivered to Switch 15.40 Watts 30.00 Watts
Max. Power Consumption 130W 250W
Voltage Range to PD 37.0-57.0V 42.5-57.0V
Cabling Cat3&Cat5 Cat5

PoE Switch vs PoE+ Switch: Selection Dilemma?

Many users may run into this problem. Should I choose PoE or PoE+ switch?

  • When to Choose PoE Switch

PoE switch provides enough power for most wireless access points, such as surveillance cameras and IP phones. Therefore, if your office is equipped with PoE switch and you are not planning to add high-end systems, then you probably don’t need a PoE+ switch. PoE switch is the simple choice for those who look for an easy setup for basic networking, which uses standard copper Ethernet cables, making it as simple as setting up a regular network. In addition, the price of it is more cheaper and affordable than a PoE+ switch.

  • When to Choose PoE+ Switch

If you want to invest in modern and advanced technological systems like VoIP, IP Cameras, Video Conferencing System (VCS) and etc, you should go for PoE+ switch. It provides dynamic power allocation, optimized power distribution and supreme power-supply utilization. IEEE standards require that PoE+ utilizes a Cat5 cable only which lowers the chance of possible impedance and reduces power dissipation.

Conclusion

PoE switch and PoE+ switch rationalize both of the processes of powering and providing data to the devices, which make them become straightforward and reliable equipment. In a word, for home network, a simple and cost-effective PoE is adequate. For business network, the PoE+ can support a more complete range of network devices. For more reliable 24 port PoE switch and 48 port PoE switch, FS would be a good choice.

Understanding Combo SFP Port on Ethernet Switch

For new comers who are not familiar with the structure and functionality of Ethernet switch, they are apt to get confused with different ports built in for different connection. Except for those common ports on SFP switch, such as SFP port , there is another port called “combo SFP port”. Do you know what is it and what is the difference between SFP port and combo SFP port? In this article we aim to give you comprehensive understanding of combo SFP port on Ethernet switch.

What Is Combo SFP Port on Ethernet Switch?

In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector. In other words, this is a compound port which can share the same switch fabric, port number and allow the users to configure their SFP switch according to different applications. But the two different physical ports can not be used simultaneously. It means that you can either plug a cable into copper 10/100/1000 interface, or plug the cable into SFP slot.

A combo SFP port is a way to provide different types of connectivity and give users the power and flexibility to configure SFP switch for unique application requirements. Below is the demonstration of 4 combo SFP ports on FS SFP switch.

What Is the Difference Between SFP Port and Combo Port?

Combo interface, also known as optoelectronic multiplexing interface which is a switch device panel with two Ethernet ports: an optical port and an electrical port. Combo electrical port and its corresponding optical port are logically multiplexed, and the user can choose which one to use according to the actual network demand. But when one of the ports is activated, the other port is automatically blocked since they can not be used at the same time.

While SFP port (mini-GBIC port), a small form-factor hot pluggable interface, is designed for high speed and density SFP connection. SFP ports on SFP switch support both copper and optical links. When SFP ports on SFP switch are inserted into SFP modules with electrical ports, Ethernet copper cables are needed for data transmission. If SFP ports are plugged by SFP optical modules with optical ports, then fiber patch cables are required.

Introduction to FS.COM 24 Port Switch With 4 Combo SFP Ports

There are many SFP switches with combo SFP ports, but today we are going to take FS S3800-24F4S: 24 port switch with 4 combo SFP ports as an example to illustrate the usage of combo SFP ports on a SFP switch.

The 4 combo SFP ports on switch facilitate the application of different connectivity, making it more flexible to configure the switch. In addition, this diversiform port combination form provides a high bandwidth aggregation connectivity for multiple switches to enhance network capacity. All in all, this 24-port Gigabit managed switch is fit for enterprise network operators who pursue high performance and low power processor to provide full speed forwarding and line-dormant capacity.

Conclusion

From the above introduction, we have known that combo SFP port on SFP switch is a port type to carry out different connection applications. For combo SFP ports on Ethernet switch, only one of the twisted pair port or SFP slot can be used. For SFP ports on SFP switch, it can be either plugged into Ethernet copper cable with RJ45 SFP module, or optical fiber cable with fiber SFP module to achieve short and long reach distance transmission. What is more, FS S3800-24F4S is a good example of combo SFP ports on switch. If you have any need, FS would be a choice.
