Ma transceivers opangira ma fiber optic nthawi zambiri amagwiritsidwa ntchito awiriawiri pama waya opangira mkuwa kuti atalikitse mtunda wotumizira.Komabe, muukonde woterewu wa ma transceivers opangira ma fiber omwe amagwiritsidwa ntchito pawiri, ngati chingwe cha optical kapena chingwe chamkuwa kumbali imodzi chikulephera ndipo sichitumiza deta, transceiver ya optical fiber kumbali ina idzapitiriza kugwira ntchito ndipo sichitumiza deta network.Woyang'anira adanena za cholakwikacho.Ndiye mungathetse bwanji mavuto ngati amenewa?Ma transceivers a Fiber optic okhala ndi FEF ndi LFP amatha kuthetsa vutoli.

Kodi FEF pa fiber optic transceiver ndi chiyani?

FEF imayimira Far End Fault.Ndi protocol yomwe imagwirizana ndi muyezo wa IEEE 802.3u ndipo imatha kuzindikira cholakwika cha ulalo wakutali pamaneti.Ndi transceiver ya optical fiber ndi ntchito ya FEF, woyang'anira maukonde amatha kuzindikira mosavuta cholakwika pa ulalo wa optical fiber transceiver.Pamene cholakwika cha ulalo wa ulusi chizindikirika, cholumikizira cha fiber kumbali imodzi chimatumiza chizindikiro chakutali kudzera mu ulusi kuti udziwitse transceiver ya fiber kumbali inayo kuti kulephera kwachitika. kulumikizidwa zokha.Pogwiritsa ntchito fiber optic transceiver yokhala ndi FEF, mutha kuzindikira cholakwika pa ulalo ndikuthetsa nthawi yomweyo.Podula ulalo wolakwika ndikutumiza cholakwika chakutali kubwerera ku fiber optic transceiver, mutha kuletsa kutumiza kwa data ku ulalo wolakwika.

Kodi transceiver ya kuwala yokhala ndi ntchito ya FEF imagwira ntchito bwanji?

1. Ngati kulephera kumachitika pamapeto olandila (RX) a ulalo wa fiber, fiber transceiver A yokhala ndi ntchito ya FEF idzazindikira kulephera.

2. Fiber optic transceiver A idzatumiza cholakwika chakutali kwa fiber optic transceiver B kuti adziwitse mapeto olandira a kulephera, motero amalepheretsa kutumiza kwa fiber optic transceiver A kuti atumize deta.

3. Optical fiber transceiver A ichotsa chingwe chamkuwa cholumikizidwa ndi switch yoyandikana nayo ya Efaneti.Pakusintha uku, chizindikiro cha LED chiwonetsa kuti ulalo wachotsedwa.

4. Kumbali ina, fiber optic transceiver B idzachotsanso ulalo wa mkuwa wa kusintha kwake koyandikana, ndipo chizindikiro cha LED pazitsulo zofananira chidzasonyezanso kuti chiyanjanochi chachotsedwa.
