Njengengxenye ebalulekile yokudluliselwa kwenethiwekhi ye-optical, i-optical fibre module isebenza njengokuguqulwa kwe-photoelectric, ukuze amasignali adluliselwe kuma-optical fibers.Ngakho-ke, uyazi ukuthi ungahlukanisa kanjani ukuthi ii-optical fiber module iyimodi eyodwanoma amamodi amaningi?Nazi izindlela ezimbalwa zokuhlukanisa phakathi kwamamojula wefayibha yemodi eminingi kanye namamojula wefiber yemodi eyodwa.
Okokuqala, singabheka imingcele ye-wavelength ye-optical fiber module.Ngokuvamile, ubude be-wavelength be-optical fibre module yi-850nm, futhi i-optical fiber module iyi-multimode optical fiber module.Ubude begagasi bemodyuli ye-fiber optical yemodi eyodwa ngokuvamile bungu-1310nm, 1330nm, 1490nm, 1550nm, njll. Ngaphezu kwalokho, imojula yokukhanya kombala we-CWDM kanye nemojuli yokukhanya kombala we-DWDM kokubili amamojula we-fiber yemodi eyodwa.
Okwesibili, singabheka ibanga lokudlulisela lamamojula we-fiber optic.Ibanga lokudlulisela lamamojula we-multimode fiber optic ngokuvamile lingaphansi kuka-2km, okudingeka lisetshenziswe nama-multimode fiber jumpers.Ibanga lokudlulisa lemojula ye-fiber optical yemodi eyodwa ngokuvamile lingaphezulu kuka-2km, imojula ye-Gigabit yemodi eyodwa ye-fiber optical ingadlulisa ifike ku-160km, kanti i-10-Gigabit single-mode optical fiber module ingadlulisa ifike ku-100km.
Okwesithathu, singabheka izinhlobo zezingxenye ze-optical ze-fiber optic module.Idivayisi ekhipha ukukhanya kwe-multimode fibre optic module yi-VCSEL, futhi idivayisi ekhipha ukukhanya yemodyuli ye-fiber optic yemodi eyodwa yi-DFB, EML, FP, njll.
Okwesine, singahlulela imodi eyodwa noma imodi eminingi kusukela kumbala weringi yokudonsa yemojuli ye-fiber optic.Umbala wendandatho yokudonsa ye-multimode fiber optic module enezinga lokudlulisela elingaphansi kwe-40G (ngaphandle kwe-40G) ngokuvamile limnyama, i-40G nangaphezulu (kuhlanganise ne-40G) Umbala wendandatho yokudonsa ye-multimode fiber optic module yi-beige.Indandatho yokudonsa yemoduli ye-fiber yemodi eyodwa enobude begagasi obungu-1310nm iluhlaza okwesibhakabhaka.Ngaphezu kwalokho, kuneminye imibala yokudonsa indandatho.Wonke angamamojula wefiber yemodi eyodwa.
Ukwazi uhlobo lwefayibha (imodi eyodwa/imodi eminingi) ye-fiber optic module isisiza ukuba sikhethe i-fiber jumper ehambisanayo ngendlela efanele.
