Yintoni isixhobo optical, a BOSA
Isixhobo sokubona iBOSA siyinxalenye yemodyuli ye-optical ekhoyo, equka izixhobo ezinjengokusasaza kunye nokwamkela.
Inxalenye ye-optical transmission ibizwa ngokuba yi-TOSA, i-optical reception part ibizwa ngokuba yi-ROSA, kwaye ezi zimbini zidibene zibizwa ngokuba yi-BOSA.
Umgaqo wayo wokusebenza: ngolwazi lwesignali ye-optical (uphawu lombane) kwisignali yombane (umqondiso we-optical) isixhobo sokuguqula.
Umzobo obonakalayo:
Umzobo wesakhiwo sesixhobo seBOSA
I-BOSA ikakhulu ibandakanya la macandelo alandelayo:
1. Qalisa i-LD engundoqo kunye nokufumana i-PD-TIA engundoqo;
2. Isihluzo, i-0 kunye ne-45 degrees;esi sixhobo siyimfuneko ekugqithiseni nasekufumaneni umgca we-optical;
3. I-Isolator, khetha i-isolator ezahlukeneyo ngokobude obuhlukeneyo be-optical wavelength;kodwa ngoku abavelisi ngokubanzi bagcina esi sixhobo (ixabiso kunye nenkqubo), ingxaki ngqo kukuba isiphumo Umzobo we-Eye diagram jitter, kufuneka udibanise ngaphandle;
4. I-Adapter kunye neePigtails, ezikhethwe ngokweendleko ezahlukeneyo kunye neemeko zesicelo;
5. Isiseko.
Inkqubo yokudibanisa
I-1.I-glue igxininiswe kwisiseko kwaye yomiswa kwiqondo lokushisa eliphezulu;
I-2.I-Adapter kunye nekhonkco yenguqu idityaniswe kunye nge-laser;
3.I-adapter idibaniswe nendandatho yenguqu kwaye isiseko sihlanganiswe nge-laser;
4.Launch core kunye nesiseko cofa kuqala, kwaye ke laser indawo welding;
5.I-receiver core idityaniswa kuqala, emva koko ifakwe iglu, kwaye ekugqibeleni yomiswe kwiqondo lokushisa eliphezulu;
