Ngu-Admin / 28 Jul 20 /0Amazwana Ayini amanethiwekhi okubona asebenzayo (AON) kanye ne-passive (PON)? Yini i-AON? I-AON iyinethiwekhi ye-optical esebenzayo, ikakhulukazi yamukela ukwakhiwa kwenethiwekhi ye-point-to-point (PTP), futhi umsebenzisi ngamunye angaba nomugqa we-fiber optical ozinikele. Inethiwekhi yokubona esebenzayo isho ukuthunyelwa kwama-router, ama-switching aggregator, okokusebenza okubonakalayo okusebenzayo nezinye izisetshenziswa ezishintshayo...

Ngenxa yalokho, ukudluliselwa kwe-optical kwazalwa. Ukuhanjiswa kwe-Optical kunezinzuzo ze ... Funda kabanzi Ngomlawuli / 21 Jul 20 /0Amazwana Isingeniso kanye nokusetshenziswa kwe-EPON optical module kanye ne-GPON optical module I-PON ibhekisela kunethiwekhi ye-fiber optical fibre, okuyindlela ebalulekile ukuze kuqhutshwe izinsiza zenethiwekhi yokufinyelela kwe-broadband. Ubuchwepheshe be-PON baqala ngo-1995. Kamuva, ngokomehluko phakathi kwesendlalelo sesixhumanisi sedatha kanye nongqimba olubonakalayo, ubuchwepheshe be-PON bahlukaniswa kancane kancane ku-APON... Funda kabanzi Ngomlawuli / 17 Jul 20 /0Amazwana Iyini i-fiber optical? Izici nokuhlukaniswa kwe-fiber optical I-Optical fiber idlulisa amasignali ngendlela yama-pulses alula, futhi isebenzisa ingilazi noma i-plexiglass njengendlela yokudlulisa inethiwekhi. Iqukethe i-fiber core, i-cladding kanye nesembozo sokuzivikela. I-Optical fiber ingahlukaniswa ibe i-Single Mode fiber kanye ne-Multiple Mode fiber. I-fiber optical yemodi eyodwa kuphela ifakazela... Funda kabanzi Ngomlawuli / 14 Jul 20 /0Amazwana Qonda ngokushesha i-FTTx FTTC FTTB FTTH Yini i-FTTx? I-FTTx ithi “Fiber To The x” futhi yitemu elivamile lokufinyelela ifayibha kwezokuxhumana ze-fiber optic. x imele indawo yomugqa wefayibha. Okufana nokuthi x = H (Ifayibha Eya Ekhaya), x = O (Ifayibha Ehhovisi), x = B (I-Fiber eya Esakhiweni). Ubuchwepheshe be-FTTx busukela... Funda kabanzi Ngomlawuli / 10 Jul 20 /0Amazwana Ingabe amamojula we-SFP optical angasetshenziswa ku-SFP+ Slots? Amamojula we-SFP optical angafakwa kumachweba we-SFP+ ezimweni eziningi. Nakuba imodeli ethile yokushintsha ingaqiniseki, ngokokuhlangenwe nakho, amamojula we-SFP optical angasebenza ku-SFP + Slots, kodwa amamojula we-SFP + optical awakwazi ukusebenza kuma-slots e-SFP. Uma ufaka imojuli ye-SFP embobeni ye-SFP+, i-spe... Funda kabanzi << < Edlule49505152535455Okulandelayo >>> Ikhasi 52/74
