Njengenxalenye ebalulekileyo yokuhanjiswa kwenethiwekhi ye-optical, imodyuli ye-fiber optical isebenza njengokuguqulwa kwe-photoelectric, ukwenzela ukuba izibonakaliso zidluliselwe kwiifiber optical. Ke, uyayazi indlela yokwahlula ukuba iImodyuli yefiber optical yimowudi enyeokanye iimowudi ezininzi? Nazi iindlela ezimbalwa zokwahlula phakathi kweemodyuli zefayibha zemowudi ezininzi kunye neemodyuli zefiber zemowudi enye.
Okokuqala, sinokujonga iiparamitha ze-wavelength yemodyuli yefiber optical. Ngokuqhelekileyo, ubude bemodyuli ye-fiber optical yi-850nm, kwaye imodyuli ye-fiber optical yimodyuli ye-fiber optical multimode. Ubude bemodyuli ye-modyuli ye-fiber optical fiber ngokubanzi i-1310nm, 1330nm, 1490nm, 1550nm, njl. Ukongezelela, imodyuli yokukhanya kombala we-CWDM kunye ne-DWDM imodyuli yokukhanya kombala zombini iimodyuli ze-fiber mode eyodwa.
Okwesibini, sinokujonga umgama wokuhanjiswa kweemodyuli zefiber optic. Umgama wothumelo lweemodyuli ze-fiber optic ye-multimode ngokuqhelekileyo ingaphantsi kwe-2km, efuna ukusetyenziswa kunye ne-multimode fiber jumpers. Umgama wokuhanjiswa kwemodyuli ye-fiber optical mode ingaphezulu kwe-2km, imodyuli ye-Gigabit ye-fiber optical mode enye inokuhambisa ukuya kuthi ga kwi-160km, kunye ne-10-Gigabit imodyuli ye-fiber optical yemodyuli ingahambisa ukuya kwi-100km.
Okwesithathu, sinokujonga kwiindidi zamacandelo e-fiber optic module. Isixhobo sokukhanyisa ukukhanya kwemodyuli ye-fiber optic ye-multimode yi-VCSEL, kunye nesixhobo sokukhanyisa ukukhanya kwemodyuli ye-fiber optic ye-modyuli eyodwa yi-DFB, EML, FP, njl.
Okwesine, sinokugweba imodi enye okanye i-multi-mode ukusuka kumbala we-ring ring ye-fiber optic module. Umbala wokutsala umnxeba wemodyuli ye-fiber optic ye-multimode enezinga lokudlulisela elingaphantsi kwe-40G (ngaphandle kwe-40G) ngokuqhelekileyo imnyama, i-40G nangaphezulu (kubandakanywa ne-40G) Umbala we-ring ring ye-multimode fiber optic module yi-beige. Umsesane wokutsala wemodyuli ye-fiber yemodyuli enye ene-wavelength ye-1310nm eluhlaza okwesibhakabhaka. Ukongeza, kukho eminye imibala yokutsala umsesane. Zonke ziimodyuli zefiber zemowudi enye.
Ukwazi uhlobo lwefayibha (indlela enye/iindlela ezininzi) yemodyuli yefiber optic isinceda ukuba sikhethe i-fiber jumper ehambelanayo ngokuchanekileyo.
