    Isixhumi esibonakalayo phakathi kwefiber optical kanye nedivayisi

    Isikhathi sokuthumela: Feb-22-2023

    Ngokuxhumana okubonakalayo, ukuxhumana okubonakalayo kwamadivayisi kuxhunywe nge-fiber optical. Isibonelo, ukuxhumana phakathiOLTfuthiI-ONU(ngokuvamile, imojuli ye-SFP optical iyadingeka ukuze unikeze uxhumano lwe-optical interfaceOLT), futhi ukudluliswa kwedatha phakathi kwama-transceiver amabili e-fiber optical nakho kwenziwa nge-fiber optical, ngakho igama lesixhumi esibonakalayo liba ulwazi oluyisisekelo kakhulu ekuxhumaneni kwe-optical.

    Kunezinhlobo ezimbili ze-optical fibre interfaces: ngesakhiwo nangobuso bokuphela. Lezi zigaba ezimbili azihlukani, kodwa ziyaphilisana. Njenge-SC/APC esithombeni esingezansi, i-SC yangaphambili ingenye yezigaba ezihleliwe, futhi i-APC yokugcina ingesinye sezigaba zokuphela.

    Ukuhlukaniswa kwesakhiwo

    1. FC round thread

    Isixhumi esibonakalayo se-FC se-fiber optical sinendawo ephakanyiswe kancane, futhi isixhumi esibonakalayo se-FC sedivayisi ephambene sinendawo yegebe. Zombili zidinga ukuhambisana. Ngemuva kokuqondisa, faka i-fiber optical bese uzungezisa isakhiwo sangaphandle (nut) ukuze uqedele ukulungiswa. Uma iqhubu lingahambelani negebe, qinisa inati, futhi ukudluliswa kokukhanya phakathi kokubili kuzoba nokulahlekelwa okukhulu.
    Izinzuzo: Ngemva kokuba isikhundla siqondaniswe futhi siqiniswe, i-fiber optical kanye nedivayisi kuxhunywe ngokuqinile.
    Ukungalungi: Ukuxhuma kuyinkimbinkimbi futhi ukufakwa kuthatha isikhathi eside.

    2. ST insayeya uhlobo oluyindilinga
    Ikhanda le-ST lilungiswa yi-bayonet ngemva kokuba lifakwe futhi lizungezwe ingxenye yesiyingi. Ububi ukuthi kulula ukuphuka.

    3. SC insayeya isikwele umlomo omkhulu
    Ngokuyinhloko ibhekisela endaweni engaguquki yepulaki kanye nohlobo lwe-latch (isibalo esingezansi kwesokunxele yi-SFP optical module)
    Izinzuzo: ukuxhuma okuqondile okulula nokusebenza okulula
    Ukubi: Uma kuqhathaniswa ne-FC interface, ukuxhumana akuqinile kakhulu.

    4. LC umlomo wesikwele esincane
    I-LC incane kune-SC ngokwefiber core nokubukeka kwayo. I-LC iyi-modular jack (RJ) latch mechanism

    Qeda ukuhlukaniswa kobuso

    1. I-PC microsphere surface grinding and polishing

    I-PC (Ukuxhumana Nomzimba) kusho ukuthintana ngokomzimba. Ukukhanya kuphuma ekugcineni kwefiber optical. Nakuba ubuso bokuphela kwesiphetho busobala futhi buvumela ukukhanya ukuthi kudlule, kusazoba khona ukukhanya okubonakala emuva, okubizwa ngokuthi i-back reflection. Ukukhanya okubonisiwe akuhlangabezani nesiqondiso sokudlulisa okulindelekile futhi kudinga ukucindezelwa. Izinga lokuvinjelwa libizwa ngokuthi ukulahlekelwa kokubuya. I-PC kancane kancane ithathelwe indawo yi-UPC.

    2, UPC

    I-UPC (I-Ultra Physical Contact). I-UPC ithuthukiswa ngesisekelo se-PC. Ubuso bokugcina be-UPC bugobile kancane. Ngemuva kokupholishwa isikhathi eside, inomphumela ongcono wendawo kanye nokulahlekelwa okungcono kokubuyisela kunesakhiwo se-PC, kodwa ayiqinile ngokwanele. Ukuxhuma nokuxhuma okuphindaphindiwe kuzoholela ekwehleni kwekhwalithi yendawo kanye nokusebenza kokugcina. Ukubonakala kwegobolondo lefiber optical ku-UPC ekupheleni kobuso ngokuvamile kuluhlaza okwesibhakabhaka.

    3. I-APC ikwi-engeli engu-8 degrees futhi i-microsphere surface iyagaya futhi ipholishwe

    Uma kuqhathaniswa ne-PC, i-APC izoba nokuthambekela kwe-engeli ethile, futhi i-radius yokugcina yokufaka ipholishwa nge-engeli engu-8 °, ngaleyo ndlela inciphise ukubukeka kwangemuva. Ukulahleka kokubuya kokubona kwesixhumi se-APC ngu-60dB noma ngaphezulu, okuphakeme kunezinye izinhlobo zezixhumi. Izixhumi ze-APC zingamataniswa kuphela nezinye izixhumi ezipholishiwe nge-engeli, kodwa hhayi ngezixhumi ezingapholishiwe nge-engeli, uma kungenjalo zizobangela ukulahlekelwa okukhulu kokufaka. Ukubukeka kwegobolondo le-fiber optical ku-APC ekupheleni kobuso ngokuvamile kuluhlaza.

    Ezinye izingeniso

    Ipuleti le-flange

    Xhuma izixhumanisi ezimbili zefiber optical ukuze unwebe indlela yokubona. Qaphela ukuthi ubuso bokuphela kwe-APC nobuso bokuphela be-UPC abukwazi ukuxutshwa.

    Isigqoko sothuli

    Isetshenziselwa ukuvimbela uthuli ukuvimbela i-fiber core end face ekungcolisweni, okuzothinta ukuhanjiswa kwesignali ye-optical
