PoE Switch vs. PoE Injector: Which One to Choose?

Network has become an essential part of our daily life. To make life easier, there are various types of network devices on the market, such as such as IP phone, wireless access point and IP camera. Each of them not only has to get access to the network through the Ethernet cable, but also needs power supply via power cord. When the number of devices is a little more, the cabling will be complicated. How to solve this problem? Recently, PoE (Power over Ethernet) technology is popular, which can transmit both power and data through an Ethernet cable at the same time. When it comes to PoE, there are two hot devices: PoE switch and PoE injector. And people often ask: PoE switch vs. PoE injector: which one to choose? This article will make a comparison between them and help you make the choice.

PoE Switch vs. PoE Injector: What is PoE Switch?

PoE switch is a network switch that has Power over Ethernet injection built-in. When connected with other network devices, PoE switch will detect whether they are PoE-compatible and enable power automatically. Therefore, it is a simple solution to add PoE to your network by using PoE switch. In addition, there is PoE+ switch available on the market. PoE switch utilizes the original PoE standard, IEEE 802.3af, which provides up to 15.4W of DC power to each device. While PoE+ switch use the latest PoE+ standard, IEEE 802.3at, also known as PoE class 4, which provides up to 30W of power to each device. That’s to say PoE+ switch can provide almost twice as much power as PoE switch. The following figure shows a 8-port PoE switch which is popular among many users.

PoE Switch vs. PoE Injector: What is PoE Injector?

PoE injector is used to add PoE capability to regular non-PoE network links. The following figure shows the application of PoE injector. Both PoE injector and non-PoE Ethernet switch are powered on. Then they are connected by an Ethernet cable. By doing this, the PoE-compatible IP phone, wireless access point and IP camera can work through one Ethernet cable respectively connected to PoE injector. In network deployment, PoE injector can provide a versatile solution when fewer PoE ports are required.

PoE Switch vs. PoE Injector: Which One to Choose?

PoE switch is all-in-one box with no additional appliance and the ports on it can be used to manage both network and power. While PoE injector can be added onto existing networks with no need to change the switch and is easy to mount anywhere. As for which one to choose, it really depends on the specific requirement. For example:

If you only have a few things to power, then PoE injectors are good. The cost is lower when compared to a PoE switch.
If the PoE goes out in a PoE switch, all PoE has the chance of going out. But if a PoE injector goes out, it only affects one device.
If you do have to replace a PoE injector, you can just replace the bad injector without any production downtime anywhere else in the network.

Conclusion

Both PoE switch and PoE injector utilize PoE technology which makes network deployment even simpler and have their own advantages. It is important to figure out what you need before you make a choice between them. What’s more, please ensure your device supports PoE before connecting into a PoE-enabled network. PoE Switch Vs. PoE Injector, hope this article is helpful for you.

Talk About 2.5G And 5G

Network technology is developing rapidly. To keep up with the trend, data centers are required to upgrade constantly, from 10G to 40G, 40G to 100G and even 100G to 400G. However, for some small business data centers with 1G infrastructures, directly migrating from 1G to 10G is a little fast. Is there any slower Ethernet standards to fill the gap between 1G Ethernet and 10G Ethernet speeds? The answer is Yes—2.5 Ethernet and 5G Ethernet. This article will talk about 2.5G and 5G.

Overview of 2.5G And 5G

The physical (PHY) layer transmission technology of IEEE 802.3bz is based on 10GBASE-T but operates at a lower signaling rate. By reducing the original signal rate to 1/4 or 1/2, the transfer rate drops to 2.5 or 5 Gbit/s, respectively. The spectral bandwidth of the signal is reduced accordingly, lowering the requirements on the cabling, so that 2.5GBASE-T and 5GBASE-T can be deployed at a cable length of 100 meters on unshielded Cat5e cable and Cat6 cable, respectively. The following figure shows the comparison of twisted pair based Ethernet technologies.

Cons And Pros of 2.5G/5G Ethernet Standards

As 2.5G and 5G Ethernet standards came out after 10G Ethernet standards, there are mixed reviews for them. This part will focus on cons and pros of 2.5G/5G Ethernet standards.

Cons of 2.5G And 5G

When 2.5G Ethernet and 5G Ethernet standards came out, many people didn’t think much of them. They commented that:

5GBase-T and 5GBase-T are going to be used for wifi rollouts. And they are pretty much strictly for enterprise wireless deployments.
10GbE is getting pretty cheap. Lots of new desktop motherboards now have 10G NICs inside them and the premium seems to be less than $100 too, which isn’t too bad. What’s missing is a bunch of 10G home switches and routers.
As for availability, the 10G has 2 models out while the 2.5G and 5G are both “coming soon”. Due to the economies of scale and the penetration, 10G already has IMO. While 2.5G and 5G will never be widely adopted or supported.
There are not that many chip sets that support 2.5G Ethernet and 5G Ethernet yet as they really only got finalized. Also, most cards that support them right now support 10Gbe.

Pros of 2.5G And 5G

What exists is reasonable. One estimate is that there are 70 billion meters of Cat5e and Cat6 cabling have been sold between 2003 and 2014. With such a significant amount of existing infrastructure at stake, it’s hardly surprising that most enterprises want to extend the existing cabling, component and equipment investments in the standard Ethernet wireless closet. Therefore, it is not difficult to find that 2.5G Ethernet and 5G Ethernet standards have their advantages.

Cat5 and Cat6 cabling can’t support 10G Ethernet up to 100 meters, but they will be able to support the emerging 2.5Gbps and 5Gbps standards, thereby preserving the value of the existing copper cable plant.
Adopting new 2.5G and 5G can satisfy the need of increasing data rates of wireless networking. The new 802.11ac Wi-Fi standard increases wireless bandwidth, supporting Ethernet speeds of 1.7 Gbps to 2.5 Gbps. With the coming of the next generation of wireless networking, 802.11ac Wi-Fi Wave 2, wireless network speeds could increase to as high as 6.8 Gbps.
Besides the need from the Wi-Fi industry, a 2.5G/5G version will also aid in other applications such as enterprise infrastructure, cellular Wi-Fi offloads, small cells, security cameras, multiple industrial uses and PoE technology.
These two new Ethernet standards have plenty of attributes to ensure success, such as ease of use, backward compatibility, faster speeds without requiring a cable upgrade, incremental speed upgrades, multi-vendor interoperability, not to mention optimized cost and performance.

Conclusion

From the above content, we can conclude that 2.5G/5G Ethernet standards have both pros and cons. For those who want to upgrade cabling system to 10G, 2.5G/5G is not useful. For small business and home network, 2.5G/5G is a cost-effective solution. No matter what your cable plant is, choosing a suitable migration path is the most important thing.
