Fiber optic transceivers feem ntau yog siv ua khub hauv tooj liab-raws li cov kab hluav taws xob los txuas ntxiv qhov sib kis.Txawm li cas los xij, nyob rau hauv xws li ib tug network ntawm optical fiber transceivers siv nyob rau hauv ua khub, yog hais tias lub optical fiber los yog tooj liab cable txuas ntawm ib sab tsis ua hauj lwm thiab tsis xa cov ntaub ntawv, lub optical fiber transceiver nyob rau sab nraud yuav ua hauj lwm mus ntxiv thiab yuav tsis xa cov ntaub ntawv mus rau. lub network.Tus thawj tswj hwm tau tshaj tawm qhov yuam kev.Yog li, yuav daws cov teeb meem li cas?Fiber optic transceivers nrog FEF thiab LFP zog tuaj yeem daws qhov teeb meem no zoo kawg nkaus.

Dab tsi yog FEF ntawm fiber ntau optic transceiver?

FEF stands rau Far End Fault.Nws yog tus txheej txheem uas ua raws li IEEE 802.3u tus qauv thiab tuaj yeem kuaj xyuas qhov txhaum ntawm cov chaw taws teeb txuas hauv lub network.Nrog rau cov khoom siv fiber ntau optical transceiver nrog FEF muaj nuj nqi, tus thawj coj hauv lub network tuaj yeem yooj yim txheeb xyuas qhov txhaum ntawm qhov txuas optical fiber transceiver.Thaum kuaj pom qhov yuam kev ntawm qhov txuas fiber ntau, lub fiber ntau transceiver ntawm ib sab yuav xa cov teeb liab txhaum cai los ntawm fiber ntau kom ceeb toom rau cov fiber ntau transceiver rau sab nraud tias qhov tsis ua haujlwm tau tshwm sim.Tom qab ntawd, ob qhov txuas tooj liab txuas nrog lub fiber txuas yuav raug txiav tawm.Los ntawm kev siv fiber ntau optic transceiver nrog FEF, koj tuaj yeem yooj yim txheeb xyuas qhov txhaum ntawm qhov txuas thiab daws teeb meem tam sim ntawd.Los ntawm kev txiav tawm qhov faulty txuas thiab xa cov chaw taws teeb ua txhaum rov qab mus rau fiber ntau optic transceiver, koj tuaj yeem tiv thaiv cov ntaub ntawv xa mus rau qhov txuas faulty.

Lub optical transceiver nrog FEF muaj nuj nqi ua haujlwm li cas?

1. Yog tias qhov tsis ua haujlwm tshwm sim ntawm qhov kawg tau txais (RX) ntawm qhov txuas fiber ntau, fiber ntau transceiver A nrog FEF muaj nuj nqi yuav kuaj pom qhov tsis ua haujlwm.

2. Fiber optic transceiver A yuav xa cov chaw taws teeb ua txhaum rau fiber ntau optic transceiver B kom ceeb toom qhov tau txais qhov kawg ntawm qhov tsis ua haujlwm, yog li cuam tshuam qhov xa tawm ntawm fiber ntau optic transceiver A rau cov ntaub ntawv xa mus.

3. Optical fiber transceiver A yuav disconnect tus tooj liab cable txuas nrog nws tus nyob sib ze Ethernet hloov.Ntawm qhov hloov pauv no, qhov taw qhia LED yuav pom tias qhov txuas tau raug txiav.

4. Ntawm qhov tod tes, fiber ntau optic transceiver B tseem yuav txiav qhov txuas tooj liab ntawm nws qhov chaw sib txuas, thiab qhov taw qhia LED ntawm qhov sib txuas tseem yuav qhia tau tias qhov txuas no raug txiav.
