Njengenxalenye ebalulekileyo yokuhanjiswa kwenethiwekhi ye-optical, imodyuli ye-fiber optical isebenza njengokuguqulwa kwe-photoelectric, ukwenzela ukuba izibonakaliso zihanjiswe kwi-fiber 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 be-wavelength yemodyuli ye-fiber optical ye-single-mode ngokubanzi i-1310nm, i-1330nm, i-1490nm, i-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 imodyuli iyakwazi ukuhambisa ukuya kuthi ga kwi-160km, kunye ne-10-Gigabit imodyuli ye-fiber optical mode 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-module 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.
