I-Optical fiber transceiver iyithuluzi lokuguqula i-photoelectric eliguqukayo nelisebenzayo elidlala indima ebalulekile ku-multi-protocol photoelectric hybrid LAN. Manje, ukuze kutholwe kangcono futhi kuqedwe amaphutha esixhumanisi, amanye ama-transceiver e-fiber optical anesixhumanisi sokuhluleka (LFP) kanye nemisebenzi ye-alamu ye-remote fault (FEF).
Ngaphambi kokuba siqale ukuchaza ukuhluleka kwesixhumanisi phezu (LFP) kanye nokuhluleka okukude (FEF) imisebenzi ye-alamu yama-transceivers e-fiber, kuyadingeka ukuqonda indima ye-fiber transceivers kumanethiwekhi wendawo wendawo.
I-Optical fibre transceiver inazo zombili izimbobo zikagesi nezamehlo, ezivame ukusetshenziselwa ukuxhuma amaswishi embobo yokubona kanye namaswishi embobo kagesi ukuze kubonakale ukuguqulwa kwesithombe sikagesi phakathi kwamadivayisi amabili, njengoba kuboniswe esithombeni esingezansi:
Yiqiniso, umsebenzi oyinhloko we-optical fiber transceiver ukuguqula ukukhanya kugesi, njengebhuloho phakathi kwamadivayisi amabili angakwazi ukuxhumana ngokuqondile, kodwa indima yawo ingaphezu kwalokho.
Uma i-fiber transceiver isetshenziswa ngababili, izintambo ezisetshenzisiwe zihlanganisa okungenani izintambo ezimbili ze-fiber optic kanye nezintambo ezimbili (njengoba kukhonjisiwe ngezansi). Kuyinkimbinkimbi yale cabling eholela ekusebenzeni kwe-alamu ye-failover (LFP) kanye ne-distal fault (FEF) ye-fiber transceiver.
I-Link failover (LFP) ibhekisela kumadivayisi amabili okuxhumana axhunyiwe (ama-transceivers, amaswishi,imizila, njll.). Eyodwa (eduze nokuphela) inephutha lesixhumanisi, futhi iphutha lesixhumanisi lingadluliselwa kwesinye (isilawuli kude). Isibonelo, ama-transceiver amabili we-fiber optical A no-B anephutha lesixhumanisi embobeni kagesi ye-transceiver A, futhi i-transceiver izodlulisela iphutha lembobo kagesi embobeni yokubona. I-transceiver izoyeka ukuthumela idatha kusuka ku-optical port; Uma i-transceiver ekugcineni B yehluleka ukuthola idatha ku-transceiver ekugcineni A, iyazi ukuthi i-transceiver ekugcineni A inokwehluleka kwesixhumanisi esingu-A, futhi i-transceiver ekugcineni B iyama ukuthumela idatha kusuka kumachweba okubona kanye nawogesi. I-alamu yesixhumanisi se-Failure Over (LFP) inika amandla abaphathi benethiwekhi ukuthi bazi ngokushesha futhi baphathe amaphutha enethiwekhi futhi banciphise ukulahlekelwa okubangelwa amaphutha enethiwekhi.
Ukwehluleka kwesilawuli kude (i-FEF) kubhekisela ekuhlulekeni kwekhebuli yokubona ethumela idatha isuka ku-fiber optic transceiver A iye ku-fiber optic transceiver B, kanye nembobo yokubona ye-fiber optic transceiver A iyeka ukuthumela idatha embobeni yokubona ye-fiber optic transceiver B. Uma enye ikhebula isebenza kahle, imbobo ye-optical ye-transceiver engu-B iyaqhubeka nokuthumela idatha ku-optical port ye-A transceiver, okubangela ukwehluleka kwenethiwekhi. Iqhaza lomsebenzi we-alamu Wokuhluleka Kwekude (FEF) ukukhombisa le nkinga.
Okungenhla incazelo ye-transceiver LFP nemisebenzi ye-FEF elethwa i-Shenzhen HDV Phoelectron Technology Co., LTD. Imishini yethu yenethiwekhi ehlobene ineI-ONUuchungechunge,OLTuchungechunge, uchungechunge lwamamojula okukhanya, wamukelekile ekuxoxisaneni okwengeziwe.
