Ama-transceivers e-Fiber optic ngokuvamile asetshenziswa ngababili ezinhlelweni zezintambo ezisekelwe ethusi ukuze kunwetshwe ibanga lokudlulisela.Kodwa-ke, kunethiwekhi enjalo ye-fiber optical transceivers esetshenziswa ngababili, uma i-fiber optical noma isixhumanisi sentambo yethusi ngakolunye uhlangothi ihluleka futhi ingadluliseli idatha, i-optical fiber transceiver ngakolunye uhlangothi izoqhubeka nokusebenza futhi ngeke ithumele idatha inethiwekhi.Umlawuli ubike iphutha.Ngakho, kanjani ukuxazulula izinkinga ezinjalo?I-Fiber optic transceivers enemisebenzi ye-FEF ne-LFP ingaxazulula le nkinga ngokuphelele.

Iyini i-FEF ku-fiber optic transceiver?

I-FEF imele i-Far End Fault.Kuyiphrothokholi ethobelana nezinga le-IEEE 802.3u futhi ingathola iphutha lesixhumanisi esikude kunethiwekhi.Nge-fiber optical transceiver enomsebenzi we-FEF, umlawuli wenethiwekhi angakwazi ukubona kalula iphutha kusixhumanisi se-fiber optical transceiver.Uma kutholwa iphutha lesixhumanisi sefayibha, i-fiber transceiver ohlangothini olulodwa izothumela isignali yephutha ekude ngefayibha ukuze yazise i-fiber transceiver ngakolunye uhlangothi ukuthi ukwehluleka kwenzeke.Bese, izixhumanisi ezimbili zethusi ezixhunywe kusixhumanisi sefayibha zizokwenza inqanyulwe ngokuzenzakalelayo.Ngokusebenzisa i-fiber optic transceiver ene-FEF, ungakwazi ukubona kalula iphutha kusixhumanisi bese ulixazulula ngokushesha.Ngokunqamula isixhumanisi esinephutha bese ubuyisela iphutha elikude ku-fiber optic transceiver, unganqanda ukudluliswa kwedatha kusixhumanisi esinephutha.

Isebenza kanjani i-transceiver ebonakalayo enomsebenzi we-FEF?

1. Uma ukwehluleka kwenzeka ekugcineni kokwamukela (i-RX) yesixhumanisi se-fiber, i-fiber transceiver A enomsebenzi we-FEF izobona ukwehluleka.

2. I-Fiber optic transceiver A izothumela iphutha elikude ku-fiber optic transceiver B ukuze yazise ukuphela kokwamukela kokwehluleka, ngaleyo ndlela ikhubaze ukuphela kokuthumela kwe-fiber optic transceiver A ukuze kudluliselwe idatha.

3. I-Optical fiber transceiver A izonqamula ikhebula yethusi exhunywe kuswishi ye-Ethernet engumakhelwane.Kulolu shintsho, inkomba ye-LED izobonisa ukuthi isixhumanisi sinqanyuliwe.

4. Ngakolunye uhlangothi, i-fiber optic transceiver B izophinde inqamule isixhumanisi sethusi sokushintsha kwayo okuseduze, futhi inkomba ye-LED ekushintsheni okuhambisanayo nayo izobonisa ukuthi lesi sixhumanisi sinqanyuliwe.
