Power over Ethernet (PoE)
« on: October 11, 2013, 08:08:12 AM »
Hello,

Power over Ethernet (PoE) allows both data and power to be sent across
the same twisted-pair cable, eliminating the need to provide separate power
connections. This is especially useful in areas where installing separate
power might be expensive or difficult.

PoE can be used to power many devices, including:

Voice over IP (VoIP) phones
Security cameras
Wireless access points
Thin clients

Hello,

Power over Ethernet (PoE) is a technology for wired Ethernet LANs (local area networks) that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. Doing so minimizes the number of wires that must be strung in order to install the network. The result is lower cost, less downtime, easier maintenance, and greater installation flexibility than with traditional wiring.

For PoE to work, the electrical current must go into the data cable at the power-supply end, and come out at the device end, in such a way that the current is kept separate from the data signal so that neither interferes with the other. The current enters the cable by means of a component called an injector. If the device at the other end of the cable is PoE compatible, then that device will function properly without modification. If the device is not PoE compatible, then a component called a picker or tap must be installed to remove the current from the cable. This "picked-off" current is routed to the power jack.

Thanks,
Hruthika.

Hello,

power over Ethernet is a technology which enables to connect network devices through ethernet cable. Therefore it is not necessary to use two individual lines/1x data, 1x power supply/ for assurance of data conectivity and supplying. One Ethernet line is sufficient. This technology is applicable for wide range of network products such as Access Points, Routers, IP cameras, modems, switches, embedded computers or other network products.

Thanks
priyanka

Hello,

Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras. Unlike standards such as Universal Serial Bus which also power devices over the data cables, PoE allows long cable lengths. Power may be carried on the same conductors as the data, or it may be carried on dedicated conductors in the same cable.

Thanks

hello


Power over Ethernet (PoE) is a technology that integrates power into a standard LAN infrastructure. It enables power to be provided to the network device, such as an IP phone or a network camera, using the same cable as that used for network connection. It eliminates the need for power outlets at the camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure 24 hours a day, 7 days a week operation.

Thanks.
