Kunxibelelwano lwe-optical, i-optical interfaces yezixhobo zixhunyiwe nge-fiber optical. Umzekelo, unxibelelwano phakathiOLTkwayeI-ONU(ukuthetha ngokubanzi, imodyuli yokukhanya ye-SFP iyafuneka ukunika uqhagamshelwano lwe-optical interface kwiOLT), kunye nokuhanjiswa kwedatha phakathi kwee-transceivers ezimbini ze-fiber optical nazo ziqhutywa ngefiber optical, ngoko ke igama le-interface yabo liba lolona lwazi lusisiseko kunxibelelwano lwe-optical.
Kukho iindidi ezimbini zojongano lwefiber optical: ngokwesakhiwo kunye nobuso besiphelo. Olu lwahlulo lumbini aluhlukanga, kodwa luhlala kunye. Njenge-SC / APC kumzobo ongezantsi, i-SC yangaphambili yenye yokuhlelwa kwesigxina, kwaye i-APC yokugqibela yenye yokuhlelwa kokuphela.
Ukuhlelwa kolwakhiwo
1. FC umsonto ongqukuva
I-FC interface ye-fiber optical inendawo ephakanyisiweyo kancinane, kwaye i-FC interface yesixhobo esichaseneyo sinesithuba se-gap. Zombini kufuneka zilungelelaniswe. Emva kokulungelelaniswa, faka i-fiber optical kwaye ujikeleze isakhiwo sangaphandle (nut) ukugqiba ukulungiswa. Ukuba i-bulge ayihambelani ne-gap, qinisa i-nut, kwaye ukuhanjiswa kokukhanya phakathi kwezi zibini kuya kuba nelahleko enkulu.
Izibonelelo: Emva kokuba isikhundla silungelelaniswe kwaye siqiniswe, i-fiber optical kunye nesixhobo sixhunyiwe ngokuqinileyo.
Ukungalungi: I-plugging iyinkimbinkimbi kwaye ukufakela kuthatha ixesha elide.
2. ST bayonet uhlobo olujikelezayo
Intloko ye-ST igxininiswe yi-bayonet emva kokuba ifakwe kwaye ijikeleze isiqingatha sesangqa. Ukungalungi kukuba kulula ukuqhawula.
3. SC bayonet isikwere umlomo omkhulu
Ibhekisa ikakhulu kwindawo emiselweyo yeplagi kunye nodidi lwelatshi (umfanekiso osezantsi ngasekhohlo yimodyuli yokubona ye-SFP)
Izinto eziluncedo: ukuplaga ngokuthe ngqo okufanelekileyo kunye nokusebenza ngokulula
Ukungalungi: Xa kuthelekiswa nojongano lweFC, unxibelelwano aluqinanga kakhulu.
4. LC umlomo omncinci wesikwere
I-LC incinci kune-SC ngokubhekiselele kwi-fiber core kunye nokubonakala. I-LC yi-modular jack (RJ) latch mechanism
Phelisa ukuhlelwa kobuso
1. I-PC microsphere surface grinding and polishing
I-PC (uQhagamshelwano loMzimba) ithetha ukudibana ngokomzimba. Ukukhanya kuphuma ekupheleni kwefiber optical. Nangona isiphelo sobuso besiphelo siselubala kwaye sivumela ukukhanya ukuba kudlule, kusekho ukukhanya okubonakaliswa ngasemva, okubizwa ngokuba yi-back reflection. Ukukhanya okubonakalisiweyo akuhlangabezani nomkhombandlela olindelekileyo wothumelo kwaye kufuneka kucinezelwe. Iqondo lokuthintela libizwa ngokuba yilahleko yokubuya. I-PC iye yatshintshwa ngokuthe ngcembe yi-UPC.
2, UPC
UPC (UQhagamshelwano loMzimba ophezulu). I-UPC iphuculwe ngesiseko sePC. Ubuso besiphelo se-UPC bugobile kancinci. Emva kokupolisha ixesha elide, inomphezulu ongcono wokugqitywa kunye nelahleko engcono yokubuya kunokwakheka kwePC, kodwa ayiqinanga ngokwaneleyo. Ukufakwa ngokuphindaphindiweyo kunye nokufakwa kweplagi kuya kubangela ukuhla komgangatho ophezulu kunye nokusebenza kokugqibela. Inkangeleko yeqokobhe lefiber optical kubuso besiphelo se-UPC buzuba ngokubanzi.
3. I-APC ikwi-engile ye-8 degrees kunye ne-microsphere surface igayiwe kwaye iphuculwe
Xa kuthelekiswa ne-PC, i-APC iya kuba ne-angle inclination ethile, kwaye i-radius yokugqibela yokufaka ipholishwe kwi-angle ye-8 °, ngaloo ndlela inciphisa ukubonakaliswa ngasemva. Ilahleko yembuyekezo ye-optical ye-APC isinxibelelanisi yi-60dB okanye ngaphezulu, engaphezulu kunezinye iintlobo zezihlanganisi. Izixhumi ze-APC zinokuthi zihambelane kuphela nezinye i-angle-polished connectors, kodwa kungekhona nge-non-angle-polished connectors, ngaphandle koko kuya kubangela ilahleko ephezulu yokufaka. Imbonakalo yeqokobhe lefiber optical kubuso besiphelo se-APC buhlaza ngokubanzi.
Ezinye iintshayelelo
Ipleyiti yeFlange
Qhagamshela ujongano ezimbini zefiber optical ukwandisa umendo obonakalayo. Qaphela ukuba isiphelo sobuso be-APC kunye nobuso besiphelo se-UPC asinakuxutywa.
Umnqwazi wothuli
Isetyenziselwa ukuthintela uthuli ukunqanda ubuso be-fiber core ekupheleni ukuba bungcoliswe, nto leyo eya kuchaphazela ukuhanjiswa komqondiso we-optical.
