Li-transceivers tsa fiber optic hangata li sebelisoa ka bobeli ka har'a lits'ebetso tsa likhoele tse thehiloeng ka koporo ho atolosa sebaka sa phetisetso.Leha ho le joalo, marang-rang a joalo a li-transceivers tsa optical fiber tse sebelisoang ka bobeli, haeba khokahanyo ea optical fiber kapa koporo ka lehlakoreng le leng e hlōleha 'me e sa fetise data, optical fiber transceiver ka lehlakoreng le leng e tla tsoelapele ho sebetsa' me e ke ke ea romela data ho. marangrang.Mookameli o tlalehile phoso.Joale, mokhoa oa ho rarolla mathata a joalo?Li-transceivers tsa fiber optic tse nang le mesebetsi ea FEF le LFP li ka rarolla bothata bona hantle.

FEF ke eng ho transceiver ea fiber optic?

FEF e emetse Far End Fault.Ke protocol e lumellanang le maemo a IEEE 802.3u mme e ka lemoha phoso ea sehokelo se hole marang-rang.Ka transceiver ea optical fiber e nang le ts'ebetso ea FEF, mookameli oa marang-rang a ka lemoha habonolo phoso ho sehokelo sa optical fiber transceiver.Ha phoso ea khokahanyo ea fiber e fumanoa, fiber transceiver ka lehlakoreng le leng e tla romela letšoao la phoso le hōle ka fiber ho tsebisa fiber transceiver ka lehlakoreng le leng hore ho hloleha ho etsahetse. ho hakoa ka bohona.Ka ho sebelisa transceiver ea fiber optic e nang le FEF, u ka bona phoso habonolo sehokelong ebe oa e rarolla hanghang.Ka ho khaola sehokelo se fosahetseng le ho khutlisetsa phoso e hole ho transceiver ea fiber optic, o ka thibela phetiso ea data ho sehokelo se fosahetseng.

Transceiver ea optical e nang le ts'ebetso ea FEF e sebetsa joang?

1. Haeba ho hlōleha ho etsahala qetellong ea ho amohela (RX) ea khokahanyo ea fiber, fiber transceiver A e nang le mosebetsi oa FEF e tla lemoha ho hlōleha.

2. Fiber optic transceiver A e tla romela phoso e hole ho fiber optic transceiver B ho tsebisa pheletso e amohelang ho hloleha, ka hona e sitise pheletso ea ho romella ea fiber optic transceiver A bakeng sa phetiso ea data.

3. Optical fiber transceiver A e tla hakolla thapo ea koporo e hoketsoeng ho switjha ea eona ea boahelani ea Ethernet.Ho sesebelisoa sena, letšoao la LED le tla bontša hore sehokelo se khaotsoe.

4. Ka lehlakoreng le leng, fiber optic transceiver B e tla boela e tlose sehokelo sa koporo sa sesebelisoa sa eona se haufi, 'me letšoao la LED ho sesebelisoa se lumellanang le sona se tla bontša hore sehokelo sena se khaotsoe.
