Ngokuxhumana okubonakalayo, ukuxhumana okubonakalayo kwamadivayisi kuxhunywe nge-fiber optical.Isibonelo, ukuxhumana phakathi kwe-OLT neI-ONU(ngokuvamile, i-SFP optical module iyadingeka ukuze kuhlinzekwe uxhumano lwe-optical interface ku-OLT), futhi ukudluliswa kwedatha phakathi kwama-transceivers amabili optical fiber nakho kwenziwa nge-fiber optical, ngakho igama lesixhumi esibonakalayo liba ulwazi oluyisisekelo kakhulu ekuxhumaneni 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 ingenye yezigaba 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 insayensi 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 omncane
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 sibonisa ngale futhi buvumela ukukhanya ukuthi kudlule, kusazoba khona ukukhanya okuvela 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
