Ama-transceivers e-Fiber optic namamojula optical
Iningi lamamojula optical asetshenziswa kunethiwekhi yomgogodla wenethiwekhi ye-fiber optical, futhi i-transceiver optical imane iyidivayisi yokwandisa ikhebula lenethiwekhi. Uyini umehluko phakathi kwamamojula optical nama-transceivers optical? 1. Amamojula okukhanya ayizesekeli, ngokuvamile asetshenziswa kuphela...Funda kabanzi - Ngomphathi / 27 Aug 20 /0Amazwana
Umehluko phakathi kwe-EPON ne-GPON yetheminali yokuxhumana
Njengoba amalungu amabili ayinhloko okufinyelela kwenethiwekhi yokubona, i-EPON ne-GPON ngayinye inokufaneleka kwayo, iyaqhudelana, iyaphelelisana, futhi ifunda komunye nomunye. Okulandelayo kuzoziqhathanisa ezicini ezihlukahlukene. Isilinganiso se-EPON sinikeza isixhumanisi esingaguquki kanye ne-downlink engu-1.25 Gbps, yamukela ulayini ongu-8b/10b c...Funda kabanzi - Ngomlawuli / 13 Aug 20 /0Amazwana
Ubuchwepheshe bokhiye be-EPON
1.1 I-Passive optical splitter I-Passive optical splitter iyingxenye ebalulekile yenethiwekhi ye-PON. Umsebenzi we-passive optical splitter ukuhlukanisa amandla okubona esignali eyodwa yokubona okokufaka kokuphumayo okuningi. Imvamisa, isihlukanisi sithola ukuhlukaniswa okukhanyayo kusuka ku-1:2 kuye ku-1:32 noma ngisho ...Funda kabanzi - Ngomphathi / 08 Aug 20 /0Amazwana
Yiziphi izindlela zokufinyelela ze-FTTX ezisekelwe ku-PON?
Ukuqhathaniswa kokufinyelela kwe-FTTX okusekelwe ku-PON Okuhlanu Indlela yamanje yokufinyelela kumkhawulokudonsa ophezulu wenethiwekhi isekelwe kakhulu ekufinyeleleni kwe-FTTX okusekelwe ku-PON. Izici eziyinhloko nokuqagela okuhilelekile ekuhlaziyeni izindleko kungokulandelayo: ● Izindleko zemishini yesigaba sokufinyelela (okuhlanganisa amathuluzi okufinyelela ahlukahlukene kanye nemigqa...Funda kabanzi - Ngomlawuli / 05 Aug 20 /0Amazwana
Iyini i-GPON? GPON izici zobuchwepheshe isingeniso
Iyini i-GPON? Ubuchwepheshe be-GPON (Gigabit-Capable PON) yisizukulwane sakamuva se-broadband passive optical integrated access standard based on the ITU-TG.984.x standard. Inezinzuzo eziningi ezifana nomkhawulokudonsa ophezulu, ukusebenza kahle okuphezulu, ukumbozwa okukhulu, nokuxhumana okucebile komsebenzisi. Abasebenzisi abaningi babheka ...Funda kabanzi - Ngomlawuli / 30 Jul 20 /0Amazwana
Izibani ezimbalwa zemodemu yefayibha ye-Optical zivamile futhi isimo sesignali yokukhanya yemodemu ye-Optical sijwayelekile kanye nokuhlaziywa kokwehluleka.
Kunamalambu amaningi esignali kumodemu ye-fiber optic, futhi singahlulela ukuthi okokusebenza nenethiwekhi kuyiphutha yini ngokukhanya kwenkomba. Nazi ezinye izinkomba ezijwayelekile zemodemu nezincazelo zazo, sicela ubheke isingeniso esinemininingwane ngezansi. 1. Ukuze kube lula indawo...Funda kabanzi
