Abakiriya bamwe babajije, hari isoko rya POE ku isoko bavuga ko rishobora kohereza metero 150 cyangwa metero 250, ni ukuri cyangwa ni ibinyoma?

Mbere ya byose, dukeneye kumva POE icyo aricyo.POE ni impfunyapfunyo ya Power hejuru ya Ethernet, bivuze ko nta gihindutse kubikorwa remezo bya Ethernet Cat.5 bihari, birashobora gukoreshwa kubintu bimwe na bimwe bishingiye kuri IP (nka terefone ya IP).Ikoranabuhanga rishobora gutanga imbaraga za DC kubikoresho nkibi mugihe cyohereza ibimenyetso byamakuru, nkibikoresho bitagendanwa bya LAN, APs, na kamera zurusobe, ni switch ishigikira Power hejuru ya Ethernet.

Igipimo cya Ethernet giteganya ko intera ntarengwa yo kohereza ari metero 100, kandi gutinda kwamakuru no gutakaza paki bishobora kubaho mugihe intera irenze metero 100.
Ariko insinga zose zumuyoboro ntizigera kuri metero 100.Mubikorwa nyabyo, umugozi wurusobe urashobora kandi kohereza neza metero zirenga 100, kandi ubuziranenge bushobora kugera kuri metero 120, ni ukuvuga umuringa wa ogisijeni utagira ogisijeni Cat.5, cyangwa icyiciro cya 6 cyumuyoboro.

Abakora PoE benshi ubu barimo gutangiza metero 150, intera ndende, amashanyarazi ya metero 250, ndetse na metero 500 zoherejwe na POE.Ntabwo bivuze ko ihererekanyabubasha ryimyanya isanzwe ya POE ari metero 100, kandi nibyiza kugenzura intera muri metero 80 mugukoresha nyabyo.Ikibazo ni ikihe?

Twese tuzi ko intera itangwa rya PoE igenwa nintera yo kohereza amakuru yikimenyetso.Amashanyarazi meza arashobora koherezwa kure cyane, ariko intera yoherejwe yikimenyetso cyamakuru igenwa numuyoboro.Intera yohererezanya icyiciro gisanzwe 5 amakuru ya kabili ni nka metero 100.Kugirango tumenye neza ubwubatsi, muri rusange ni metero 80-90.Nyamuneka menya ko intera yoherejwe hano yerekeza ku gipimo ntarengwa, nka 100M.
Ababikora benshi bagaragaje ko intera yohereza ya POE yabo ishobora kugera kuri metero 150, ariko mubikorwa nyabyo, niba abahindura POE basanzwe bashaka kugera ku ntera ya metero 150, bafite ibisabwa bikomeye ku bwiza bw’umugozi.Bagomba gukoresha ibirenze ibyiciro 6 byinsinga, byiyongera Nubwo bimeze bityo, niba umuzenguruko wimbere wa POE uhindura imiyoboro isanzwe ihindura imiyoboro hamwe na chip yo gucunga amashanyarazi ya POE, ntibishoboka kugera kumurongo wa 100M nintera yohereza. ya metero 150, kabone niyo insinga yo murwego rwohejuru ikoreshwa.Bizongera ingufu z'amashanyarazi, birengeje ingufu z'amashanyarazi ya PoE, kandi bidahindagurika cyane, hamwe nibitonyanga bikabije bipfunyika, umuvuduko mwinshi wogukwirakwiza hamwe nibimenyetso byerekana ibimenyetso, bikavamo ihungabana ryibimenyetso, gusaza kwibikoresho byahinduwe na PoE, nibibazo byo kubungabunga nyuma .

Ndetse na POE ikora cyane hamwe na 100M yuzuye yuzuye kandi ihererekanyabubasha irashobora kugera kuri metero 150 gusa.Intera yohereza metero 250 niyihe?Mubyukuri, hariho inzira.Niba igipimo cyaragabanutse kugera kuri 10M, ni ukuvuga, umurongo wohereza ni 10M, intera yoherejwe ni nziza.Kugera kuri metero 250 (ukurikije ubwiza bwumugozi wurusobe), tekinoroji ntabwo itanga umurongo mwinshi.Umuyoboro mugari uhagarikwa kuva 100M kugeza 10M, ntabwo byoroshye kohereza neza amashusho yo gukurikirana-ibisobanuro bihanitse.
Ababikora benshi, nubwo bamenyekanisha ibicuruzwa byabo kugirango bashyigikire metero 250, ntibavuga kugabanuka kugera kuri 10M, kandi bakekwaho guhisha nkana abakiriya.

Byongeye kandi, ntabwo POE zose zahindura zishobora kohereza metero 250 mugihe cyose umurongo wagabanutse kugera kuri 10M.Ibi kandi biterwa nubwiza bwa switch.Niba imbere yo guhinduranya chip yo guhuza imiterere ya switch ikennye cyane kandi ubushobozi bwo gucunga amashanyarazi ntibukomeye, nubwo 10M ihatirwa Transmission, nayo ntishobora kwemeza kohereza neza metero 250, ndetse na metero 150 ntishobora kugera.

Kubwibyo, mubitekerezo, kugirango ugere kuri metero 250, birakenewe ko hajyaho igishushanyo mbonera cy’ingufu za POE, kandi amashanyarazi ya POE yakira ibicuruzwa biva mu mahanga byujuje ubuziranenge.Module yo gucunga imbaraga irashobora gushishoza no guhita imenya IEEE802.3af / kurwego rusanzwe, igahita ihindura imbaraga, kandi igakoresha cores 8 icyarimwe.Ikorana buhanga ryogutanga amashanyarazi, kugirango ugere kumurimo nkuyu, ukoresheje amashanyarazi yubatswe, ibyiza byo gukoresha amashanyarazi yubatswe ni uko ashobora guhindura igishushanyo mbonera cyihariye, agahita apima ingufu zikenewe kumpera yakira hamwe nimbogamizi zohereza insinga kandi ibindi bipimo, bisesengurwa kandi bibarwa na moderi yubwenge yo gucunga amashanyarazi kandi bigatanga amabwiriza Amabwiriza yimbere yumuriro w'amashanyarazi kugirango uhindure umurongo wa voltage winjiza kugirango uhuze ingufu zikora zikoresha ibikoresho byanyuma.
