Intera yoherejwe neza ya POE itanga amashanyarazi ni metero 100, kandi birasabwa gukoresha umugozi wumuringa wa Cat 5e.Birashoboka kohereza ingufu za DC hamwe numuyoboro usanzwe wa Ethernet intera ndende, none kuki intera yoherejwe igarukira kuri metero 100?
Ikigaragara ni uko intera ntarengwa yo kohereza ya PoE ihinduka ahanini biterwa nintera yoherejwe.Iyo intera yoherejwe irenze metero 100, gutinda kwamakuru no gutakaza paki birashobora kubaho.Kubwibyo, intera yohereza ntigomba kurenga metero 100 mubikorwa byubwubatsi.

Ariko, haribisanzwe hari PoE yahinduye ifite intera yohereza kugeza kuri metero 250, irahagije mugutanga amashanyarazi maremare.Bizera kandi ko hamwe n’iterambere ry’ikoranabuhanga ryo gutanga amashanyarazi PoE mu gihe cya vuba, intera yohereza izagurwa kure.

POE IEEE 802.3af isanzwe isaba ko ingufu zisohoka ku cyambu gisohoka cya PSE ari 15.4W cyangwa 15.5W, kandi imbaraga zakiriwe nigikoresho cya PD nyuma ya metero 100 zoherejwe ntizigomba kuba munsi ya 12.95W.Ukurikije 802.3af isanzwe ifite agaciro ka 350ma, kurwanya insinga ya metero 100 bigomba kuba Ari (15.4-12.95W) / 350ma = 7 oms cyangwa (15.5-12.95) / 350ma = 7.29 oms.Umuyoboro usanzwe usanzwe wujuje iki gisabwa.IEEE 802.3af poe itanga amashanyarazi ubwayo yapimwe numuyoboro usanzwe.Impamvu yonyine yikibazo cyumurongo wa POE itanga amashanyarazi asabwa nuko insinga nyinshi zurusobe kumasoko ari insinga zumuyoboro udasanzwe kandi ntizakozwe muburyo bukurikije ibisabwa ninsinga zisanzwe.Ibikoresho by'insinga zidasanzwe zisanzwe ku isoko zirimo cyane cyane ibyuma bikozwe mu muringa, aluminiyumu yuzuye umuringa, ibyuma bikozwe mu muringa, n'ibindi. Izi nsinga zifite agaciro gakomeye ko guhangana kandi ntikwiriye gutanga amashanyarazi ya POE.Amashanyarazi ya POE agomba gukoresha insinga y'urusobe ikozwe mu muringa utagira ogisijeni, ni ukuvuga umugozi usanzwe.Tekinoroji yo gutanga amashanyarazi PoE ifite ibisabwa byinshi kurinsinga.Birasabwa ko mugukurikirana imishinga, ntugomba na rimwe kuzigama ibiciro ku nsinga.Inyungu iruta igihombo.
