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 failover (LFP) ndi ntchito za alarm remote (FEF).
Tisanayambe kufotokoza za kugwirizana failover (LFP) ndi remote fault (FEF) alarm ntchito za fiber transceivers, m'pofunika kumvetsa udindo wa ma transceivers fiber mu LAN.
Transceiver ya fiber optical ili ndi madoko amagetsi ndi ma doko owoneka, omwe amagwiritsidwa ntchito kwambiri kulumikiza doko la kuwala.kusinthandi doko lamagetsikusintha, kuti azindikire kutembenuka kwa photoelectric pakati pa zipangizo ziwirizi. Tsatanetsatane ndi motere:
Zoonadi, ntchito yaikulu ya transceiver ya optical fiber ndiyo kuyendetsa photoelectric conversion, yomwe ndi mlatho pakati pa zipangizo ziwiri zomwe sizingathe kulankhulana mwachindunji, koma ntchito yake ndi yochuluka kwambiri kuposa iyo.
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 failover yolumikizira (LFP) ndi distal fault (FEF) ntchito za alamu za fiber transceiver.
Link failover (LFP) imatanthawuza zida ziwiri zolumikizirana (transceiver,kusintha, rauta, etc.), cholakwika chimodzi (proximal) cholumikizira, cholakwika cholumikizira chikhoza kuperekedwa ku zida zina (zakutali) mwachitsanzo, ma transceivers awiri a fiber A ndi B, cholakwika cholumikizira doko la transceiver, cholakwika cha doko la transceiver ku doko lowala, kuyimitsa deta ya doko; B transceiver sangalandire data, ndiye dziwani cholakwika cha Ulalo, terminal B imayimitsa doko lowala ndi data ya doko. Link failover (LFP) alarm ntchito imathandizira oyang'anira maukonde kudziwa mwachangu ndikuthana ndi zolakwika za netiweki ndikuchepetsa kutayika komwe kumachitika chifukwa cha zolakwika za netiweki.
Kulakwitsa kwakutali (FEF) kumatanthawuza B optical fiber transceiver pamene doko la kuwala la A transceiver limasiya kutumiza deta ku doko la kuwala la B transceiver. Ngati chingwe china chikugwira ntchito bwino, doko loyang'ana la B transceiver likupitiriza kutumiza deta ku doko la A transceiver, zomwe zimapangitsa kuti maukonde alephereke. Alamu ya distal fault (FEF) ikuwonetsa vutoli.
Pamwambapa ndikufotokozera za transceiver LFP ndi FEF ntchito zobweretsedwa ndi Shenzhen HDV Phoelectronic Technology Co., LTD. Zida zathu zokhudzana ndi netiweki zili ndi mndandanda wa ONU,OLTseries, optical module series, talandiridwa kuti mupitirize kukambirana.
