Womabili amamojula we-fiber eyodwa kanye ne-dual fiber optical angadlulisela futhi awamukele. Njengoba lezi zokuxhumana ezimbili kufanele zikwazi ukudlulisa nokwamukela. Umehluko ukuthi imojuli eyodwa yefiber optical inembobo eyodwa kuphela. Ubuchwepheshe be-Wavelength division multiplexing (WDM) busetshenziselwa ukuhlanganisa ukwamukela nokudlulisa amaza ahlukene ku-fiber eyodwa, ukuhlunga ngesihlungi kumojula ye-optical, futhi ngesikhathi esifanayo uqedele ukudluliswa kwezimpawu ze-1310nm optical kanye nokwamukela amasignali optical 1550nm, noma ngokuphambene nalokho. . Ngakho-ke, imojula kufanele isetshenziswe ngababili (akunakwenzeka ukuhlukanisa i-fiber ene-wavevel transceiver efanayo).
Ngakho-ke, imodyuli eyodwa ye-fiber optical inedivayisi ye-WDM, futhi intengo iphakeme kunaleyo ye-dual fiber optical module. Njengoba amamojula we-fiber optical amabili athola futhi athola kumachweba ahlukene we-fiber optical, awaphambanisi, ngakho-ke awadingi i-WDM, ngakho-ke ama-wavelengths angafana. Intengo ishibhile kunaleyo yefayibha eyodwa, kodwa idinga izinsiza eziningi zefiber.
I-double fiber optical module kanye ne-single fibre optical module empeleni inomphumela ofanayo, umehluko kuphela ukuthi amakhasimende angakhetha i-fiber eyodwa noma i-fiber ephindwe kabili ngokwezidingo zabo.
I-Single fibre optical module ibiza kakhulu, kodwa ingonga insiza yefayibha, okuyinketho engcono kubasebenzisi abanezinsiza zefayibha ezinganele.
I-dual fiber optical module ishibhile, kodwa idinga ukusebenzisa i-fiber eyodwa ngaphezulu. Uma izinsiza ze-fiber zanele, ungakhetha i-dual fibre optical module.
