What Is a PoE Switch Used for?

The large amount of devices used by industrial applications such as transportation, public facility and manufacturing automation will give rise to the cables in a condition of disorder. With industrial devices becoming more power-hungry, the PoE technology wins a good reputation among users with the capability to provide higher power and reduce the number of cables required. In this article we will discuss what is PoE switch and what is a PoE switch used for.

What Is PoE Switch?

PoE switch is a network switch which applies Power over Ethernet technology. When connected with multiple network devices, PoE switch can support power and data transmission over one Ethernet cable at the same time which dramatically simplify the cabling process and cut network cost. PoE switch can be classified into many types, such as 8/12/24/48 port PoE switch, or unmanaged and managed PoE switch.

PoE Switch Applications

PoE switch is mainly used with IP cameras, VoIP phones and wireless access points (WAP).
  • IP camera
A PoE switch offers power supply and data connection to PoE-enabled IP camera system via network cables like Cat5, Cat5e and Cat6. Nowadays, whatever the industry or location, it is common and even necessary to use PoE managed switch for IP security camera to ensure the safety of people and business.
  • VoIP Phone
VoIP phone is the most common and original PoE application with a single connection to a wall socket. It can be remotely powered down. With PoE, only data network cable is required. PoE has promoted business communication and reduced deployment costs of VoIP.
  • Wireless
Wireless network is greatly enhanced by the usage of PoE. PoE technology revolutionizes the wireless network by providing data and electricity over the same Ethernet cable. When you use PoE managed switch, installation of controllers and access points is greatly simplified. It is considered to be the most widespread way to build enterprise wireless network.

Why Use PoE Switch?

Functionally, PoE brings many advantages to an installation, including:
Flexibility: PoE switch supplies power via an Ethernet cable and eliminates the demand for additional electrical wiring. Therefore, equipment can be installed based on where it needs to go. The combination of PoE and wireless technology allows for a practically cable-free environment.
Reliability: PoE power comes from a central and generally compatible source rather than a collection of distributed wall adapters. It can be back-up by an uninterruptible power supply.
Cost-efficient: There is no need for users to purchase and install additional electrical wires and outlets, which create significant savings on installation and maintenance costs.

Conclusion

PoE technology is less time-consuming and more economical for cable installation by carrying electrical power over network cable. It transmits both data and power supply simultaneously to network devices, such as IP camera, VoIP phones and Wireless AP. PoE switch has become a better choice in the long run if you anticipate advanced network features to meet business growth. Since stackable switch is the workhorse of the enterprise campus network, fiberstore provides not only PoE switch but also Gigabit stackable switch - 24 port switch to meet your different demand.

What is SFP+ Direct Attach Copper Cable?

DAC cable, or “Direct Attach Copper Cable”, is a type of copper cable which is similar to coaxial cable and also a form of high speed cable with SFP connectors on each end. As for the market nowadays, there are mainly three kinds of DAC according to the transmission rate: 10G SFP+ DAC, 40G QSFP+ DAC and 100G QSFP28 DAC in order to meet the increasing demand for cost-efficient delivery of more bandwidth. Today we will introduce the SFP+ DAC cable with the focus on types and advantages of SFP+ DAC cable. The Types of SFP+ Direct Attach Copper Cable SFP+ direct attach copper cable, also known as twinax cable, is an SFP+ cable assembly used in rack connections between servers and switches. It consists of a high speed copper cable and two SFP+ copper modules. It is widely used for short-distance and high speed Internet, such as gigabit network card, Gigabit switch, million server and etc. In general, SFP+ direct attach copper cable has two types, SFP+ active direct attach copper cable ...

How to Connect Ethernet Switch, Router and Modem

In the computer networking world, the three most ubiquitous pieces of equipment are Ethernet switch, router and modem. These are applied everywhere from data center to network connections in your own home. However, despite the importance of these three pieces of equipment, some people are oblivious or confused to their internal functions and connection mode. So in this article, we will attempt to explain the difference between each piece of equipment and introduce the common way to connect Ethernet switch, router and modem. What Is the Difference Between Ethernet Switch, Router and Modem From a physical perspective, a modem, router and Ethernet switch look very similar. Nevertheless, there are key differences between them internally and functionally with relevant purposes on a network. Switch: Bridge Your Devices in a Network An Ethernet switch is commonly referred to as a multi-port network bridge that processes and routes data on a data link layer (layer 2) and sometimes...
