Kuma-optical transceivers, noma ngabe i-fiber eyodwa noma i-dual fiber ingcono, ake siqale siqonde ukuthi iyini i-fiber eyodwa ne-dual fiber.

Ifayibha eyodwa: Idatha etholiwe futhi yathunyelwa idluliselwa ngefayibha eyodwa yokubona.
Ifayibha ekabili: Idatha etholiwe futhi ethunyelwe idluliswa ngamafiber optical abalulekile amabili ngokulandelana.

Amamojula e-single-fiber bidirectional optical abiza kakhulu, kodwa angalondoloza insiza yefayibha eyodwa, okuyinketho engcono kubasebenzisi abanezinsiza zefayibha ezinganele.
I-dual-fiber bidirectional optical module ishibhile, kodwa ifayibha eyodwa ngaphezulu iyadingeka.Uma izinsiza zefiber zanele, ungakhetha imojula ye-dual-fiber optical module.

Ngakho-ke buyela embuzweni odlule, ingabe ifayibha eyodwa noma i-dual fiber ingcono ku-transceiver optical?

I-single-fiber optical transceivers ingagcina ingxenye yezinsiza zekhebula le-fiber, okungukuthi, ukudluliswa kwedatha nokwamukela ku-fiber eyodwa-core, efaneleka kakhulu ezindaweni lapho izinsiza ze-fiber ziqinile;kuyilapho ama-transceiver optical ama-dual-fiber kudingeka athathe i-fiber optical ene-core-core, i-core eyodwa isetshenziselwa ukudlulisa (Tx) I-core eyodwa isetshenziselwa ukwamukela (Rx).Amaza amaza avamile we-single-fiber optical transceivers yi-1310nm kanye ne-1550nm yokusetshenziswa okubhanqiwe, okungukuthi, isiphetho esisodwa singu-1310 wavelength, kanti esinye isiphetho singu-1550 wavelength, engathumela noma yamukele.

I-dual-fiber optical transceivers wonke anobude obufanayo, okungukuthi, amadivaysi emikhawulweni yomibili asebenzisa ubude begagasi obufanayo.Kodwa-ke, njengoba lingekho indinganiso yamazwe ngamazwe ehlanganisiwe yemikhiqizo ye-optical transceiver, kungase kube nokungahambisani phakathi kwemikhiqizo yabakhiqizi abahlukene lapho ixhumeke.Ngaphezu kwalokho, ngenxa yokusetshenziswa kwe-multiplexing ye-wavelength division, imikhiqizo ye-fiber optical transceiver enezinkinga zokunciphisa isignali, futhi ukuzinza kwabo kubi kakhulu kunemikhiqizo ye-dual-fiber, okungukuthi, ama-transceivers optical single-fiber anezidingo eziphakeme zamamojula optical, ngakho-ke ama-transceiver optical we-fiber eyodwa emakethe angama-Dual-fiber optical transceivers nawo ayabiza kakhulu.

I-transceiver yemodi eminingi ithola izindlela zokudlulisa eziningi, ibanga lokudlulisela lifushane, futhi i-transceiver yemodi eyodwa ithola imodi eyodwa kuphela;ibanga lokudlulisela lide uma kuqhathaniswa.Nakuba ama-multi-mode esuswa, kusenezinhlelo zokusebenza eziningi ekuqapheni nasekudluliseleni amabanga amafushane ngenxa yenani eliphansi.Ama-transceivers anemodi eningi ahambisana namafibre anemodi eminingi, kanti imodi eyodwa kanye nemodi eyodwa iyahambisana.Azikwazi ukuxutshwa.

Njengamanje, ama-transceiver amaningi abonakalayo emakethe ayimikhiqizo ye-dual-fiber, evuthiwe futhi ezinzile, kodwa edinga izinsiza zekhebula elibonakalayo.
