How does PoE Change the Network Architecture

PoE (Power over Ethernet) is a mature technology being widely applied in communication industry nowadays, it aims to solve the trouble of power supply because devices without PoE basically need a power cord other than another cord to transmit data. There are various Power Source Equipment (PSE) like PoE switch, PoE injector, PoE media converter can be used to achieve PoE network. Here is some basic knowledge about them.

PoE Technology Overview


PoE Networking Architectures

A typical PoE system consists of a PSE and a Power Device (PD.) The PSE may generally be a PoE switch (Endspan) or a PoE hub/injector (Midspan). PSE can also be PoE fiber media converter which provides power to network devices over existing Ethernet cabling and leverage the benefits of fiber. PD is usually a PoE-enabled terminal device such as an IP phone, surveillance cameras, or wireless access point, etc. Thus, there are three types of PoE networking architectures based on different PSE:

1.Endspan PoE Switch + PDs

2. Ethernet Switch (RJ45 port) + Midspan Power Injector or Hub + PDs

3. Ethernet Switch (SFP port) + PoE Fiber Media Converter + PDs

The application of PoE has now become a trend in the industry because every single convenience could accumulate to be a huge benefit for the maintenance in the future, that’s quite important for clients who have to manage a network with increasing capacity.
