Poe Power Supply (Pouvwa sou Ethernet) se yon teknoloji ki bay ekipman pou pouvwa a aparèy tèminal pandan y ap transmèt done nan ki deja egziste Ethernet fil elektrik enfrastrikti a . eleman prensipal yo nan pouvwa PoE ekipman pou pouvwa ekipman pou (PSE) ak PNEMANS APS (PD) {} pse. Telefòn ip ak lòt aparèy .
K ap travay prensip
Teknoloji POE transmèt done ak pouvwa ansanm nan kab Ethernet . Creole Kategori 5 kab rezo a gen kat pè nan pè trese, men se sèlman de pè yo te itilize nan 10m baz-t ak 100m baz-t {{6} 3 . 84 ak 12.95W, ak maksimòm lan pa depase 13W.
Senaryo Aplikasyon
POE power supply is widely used in various devices that need to be powered and networked at the same time, such as IP phones, video surveillance, wireless access points, etc. Its advantage is that it simplifies the equipment installation and wiring process, does not require additional power sockets and cables, improves the deployment flexibility and system reliability of the equipment, and reduces the installation and maintenance Depans .
Istorik background
Estanda yo pou teknoloji POE yo defini nan IEEE 802 . 3af ak IEEE 802 . 3at {{9} IEEE 802.3at (POE+) bay pi gwo pouvwa pandan ke yo te konpatib ak 802.3af.
