Optical fiber transceiver ndi chida chosinthika komanso chogwira ntchito chosinthira zithunzi chomwe chimakhala ndi gawo lofunikira mu multi-protocol photoelectric hybrid LAN. Tsopano, kuti muwone bwino ndikuchotsa zolakwika zamalumikizidwe, ma transceivers ena optical fiber ali ndi ulalo wolephera (LFP) ndi ma alarm akutali (FEF).
Tisanayambe kufotokoza kulephera kwa ulalo pa (LFP) ndi kulephera kwakutali (FEF) ma alarm a ma transceivers a fiber, ndikofunikira kumvetsetsa ntchito ya ma transceivers a fiber pama network amderalo.
Optical fiber transceiver ili ndi madoko amagetsi ndi kuwala, omwe nthawi zambiri amagwiritsidwa ntchito kulumikiza ma switch opangira ma port ndi ma switch amagetsi kuti azindikire kusintha kwazithunzi pakati pa zida ziwiri, monga momwe chithunzi chili pansipa:
Zoonadi, ntchito yaikulu ya optical fiber transceiver ndiyo kutembenuza kuwala kwa magetsi, monga mlatho pakati pa zipangizo ziwiri zomwe sizingathe kulankhulana mwachindunji, koma udindo wake ndi wochuluka kwambiri kuposa pamenepo.
Fiber optic transceiver ikagwiritsidwa ntchito pawiri, zingwe zomwe zimagwiritsidwa ntchito zimaphatikizapo zingwe ziwiri za fiber optic ndi zingwe ziwiri (monga momwe tawonetsera pansipa). Ndizovuta za cabling izi zomwe zimatsogolera ku link failover (LFP) ndi distal fault (FEF) alamu ntchito za fiber transceiver.
Link failover (LFP) imatanthawuza zida ziwiri zoyankhulirana zolumikizidwa (transceivers, switches,ma routers, ndi zina). Mmodzi (pafupi ndi mapeto) ali ndi vuto la ulalo, ndipo vuto la ulalo limatha kuperekedwa ku chipangizo china (chakutali). Mwachitsanzo, ma transceivers awiri optical fiber A ndi B ali ndi vuto la A mu doko lamagetsi la transceiver A, ndipo transceiver imatumiza cholakwika cha doko lamagetsi ku doko la kuwala. Transceiver idzasiya kutumiza deta kuchokera pa doko la kuwala; Ngati transceiver kumapeto kwa B akulephera kulandira deta kuchokera ku transceiver kumapeto kwa A, amadziwa kuti transceiver pamapeto A ali ndi kulephera kwa A, ndipo transceiver kumapeto B amasiya kutumiza deta kuchokera ku madoko a kuwala ndi magetsi. Alamu ya Failure Over (LFP) ya ulalo imathandizira oyang'anira maukonde kudziwa mwachangu ndikuwongolera zolakwika za netiweki ndikuchepetsa kutayika komwe kumachitika chifukwa cha zolakwika za netiweki.
Kulephera kwakutali (FEF) kumatanthauza kulephera kwa chingwe cha kuwala chomwe chimatumiza deta kuchokera ku fiber optic transceiver A kupita ku fiber optic transceiver B, ndi doko la kuwala kwa fiber optic transceiver A imasiya kutumiza deta ku doko la kuwala la fiber optic transceiver B. Ngati chingwe china chikugwira ntchito bwino, doko loyang'ana la B transceiver likupitiriza kutumiza deta ku doko la kuwala kwa A transceiver, zomwe zimayambitsa kulephera kwa intaneti. Ntchito ya alamu ya Remote Failure (FEF) ndikuwonetsa vutoli.
Pamwambapa ndikufotokozera za transceiver LFP ndi FEF ntchito zobweretsedwa ndi Shenzhen HDV Phoelectron Technology Co., LTD. Zida zathu zapaintaneti zogwirizana nazoONUmndandanda,OLTseries, optical module series, talandiridwa kuti mupitirize kukambirana.
