POE ADAPTER/COMBINER (LED)
POE-IJ807
OverView:
POE (Power Over Ethernet) is a technology solution that, under the
case of no any change for current Ethernet Cat5 wiring/cabling
infrastructure, not only transfer data signal but also provide
direct current power for some IP based terminal device (like IP
telephony, Wireless LAN access point, Network camera, etc.).
POE technology can minimize the cost while ensuring the normal
operation of the existing network and the safety of the existing
structured cabling.
POE(Power over Ethernet) adapter provide a power solution for the
related device, it can supply power and simultaneously be a media
for data transfer in anywhere there is a cat5 cable.
POE also known as power system based on local area network (POL,
Power over LAN) or Active Ethernet, sometimes it is briefly called
Power Over Ethernet, this is the latest standard specification of
transferring data and delivering power while taking advantage of
existing standard Ethernet transmission cable, and preserve the
compatibility between user and the existing Ethernet system.
IEEE 802.3 is new standard of POE in the base of Ethernet power
system, which add related standard in power over network cable
directly through IEEE 802.3, it’s an extension of existing Ethernet
standard, and it is also the first international standard in power
distribution.
POE principle
There are 4 pairs of twisted pair for the standard CAT5 network
cable, but there are only 2 pairs ones are adapted/applied in 10M
BASE-T and 100M BASE-T. IEEE802.3 allows two solutions, when power
delivered through free pin, PIN 4&5 connect positive”+”, PIN
7&8 connect negative”-”, while power delivered through data
pin, add DC power on the central point of the transmission
transformer, without affecting the data transfer. In this case, pin
1&2 and pin 3&6 are at any polarity. IEEE802.3 standard
will not allow above two applications happen at the same time. The
PSE(Power Source Equipment) provide only one power solution, but
the PD(Powered Device) must be adapted to above two application
solutions at the same time.
Advantage of POE
1. Cost saving. As it’s just one instead of two pieces of net cable
for the installation. PD, in most cases, are installed at where is
hard to access AC power. Along with increasing device connected to
Ethernet, if there is no need to provide local power for device, it
will greatly reduce the cost of installation and simplify the
management.
2. It’s easy to install and manage. It allows users to use original
device and POE device together on internet automatically and
safely, which make rooms for original device coexist with Ethernet
cable.
3. It’s safety. As POE supply terminal device just provide power
for those device that need power. The Ethernet cable will generate
voltage only when it’s connected between POE and Powered Device, so
it have eliminated the dangerous of power leakage on cable line.
4. It’s easy to manage network equipment.
