1. Isingeniso senethiwekhi ye-EPON I-EPON (i-Ethernet Passive Optical Network) iwubuchwepheshe benethiwekhi yokufinyelela i-fiber optical evelayo, esebenzisa isakhiwo se-point-to-multipoint, imodi yokudlulisa i-fiber optical passive, esekelwe kuplathifomu ye-Ethernet enesivinini esikhulu kanye ne-TDM yesigaba sokuhlukanisa isikhathi se-MAC (MediaAccessControl ) mina...

1.indlela yokufaka Kungakhathaliseki ukuthi ingaphakathi endlini noma ngaphandle, kufanele uthathe izinyathelo zokulwa ne-static uma usebenzisa imojula ye-optical, futhi uqinisekise ukuthi uthinta imojuli ye-optical ngezandla zakho ngenkathi ugqoke amagilavu ​​aphikisana ne-static noma ibhande lesihlakala eliphikisana ne-static. Kwenqatshelwe ngokuphelele ukuthinta i-golden fing...

Esikhathini sanamuhla se-inthanethi, kokubili ukuthunyelwa kwenethiwekhi yebhizinisi nokwakhiwa kwesikhungo sedatha akukwazi ukwenza ngaphandle kwamamojula abonakalayo nokushintsha. Amamojula we-Optical asetshenziswa kakhulu ukuguqula amasignali kagesi ne-optical, kuyilapho amaswishi asetshenziselwa ukudlulisa amasignali e-photoelectric. Phakathi kwe-optica eminingi ...

Ama-transceivers e-fiber optical ngokuvamile asetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela. Ngasikhathi sinye, baphinde babamba iqhaza elikhulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optical ...

Sivame ukuzwa ngokushintshwa kwe-fiber optic kanye nama-transceivers e-fiber optic. Phakathi kwazo, amaswishi e-fiber optic kukhona okokudluliswa kwenethiwekhi okunesivinini esikhulu, okubuye kubizwe ngokuthi amaswishi e-fibre channel namaswishi e-SAN. Uma kuqhathaniswa nokushintsha okujwayelekile, basebenzisa izintambo ze-fiber optic njengezisetshenziswa zokudlulisela...

Ngaphambi kokuqonda ukushintshwa kwe-PoE, kufanele siqale siqonde ukuthi iyini i-PoE. I-PoE iwumthombo wamandla ngaphezu kobuchwepheshe be-Ethernet. Kuyindlela yokunikeza amandla ukude kumadivayisi enethiwekhi axhunyiwe (njenge-Wireless LAN AP, Ucingo lwe-IP, i-Bluetooth AP, Ikhamera ye-IP, njll.) kukhebuli yedatha ye-Ethernet ejwayelekile, i-el...
