Igama eligcwele lemojuli ye-optical lithii-optical transceiver, okuyithuluzi elibalulekile ohlelweni lokuxhumana lwe-fiber optical. Inesibopho sokuguqula isignali ye-optical eyamukelwe ibe isignali kagesi, noma ukuguqula isignali kagesi efakiwe ibe isignali ye-optical ezinzile ngenani elihambisanayo.
Ii-optical module yakhiwe ngamadivaysi e-optoelectronic, ama-circuits asebenzayo kanye ne-optical interfaces. Amadivayisi we-optoelectronic afaka izingxenye ezimbili: ukudlulisa (TOSA) nokwamukela (ROSA).
Imingcele ebalulekile yezobuchwepheshe yemojula ye-optical ihlanganisa amandla optical adlulisiwe, isilinganiso sokuqothulwa, ukuthola ukuzwela, namandla optical agcwele.
1. Isilinganiso samandla okubona adlulisiwe sibhekisela kuncazelo ye-arithmetic yamandla okubona lapho ilogikigi yesiginali ingu-1 kanye namandla okubona lapho ingu-0.
2. Isilinganiso sokuqothulwa sibhekisela esilinganisweni samandla okubona adlulisiwe awo wonke amakhodi "1" kumandla okubona adlulisiwe awo wonke amakhodi "0". Kuzothinta ukuzwela kokwamukela. Isilinganiso sokuqothulwa kufanele silawulwe ngaphakathi kwebanga elinengqondo. Isilinganiso esikhulu sokushabalala sihambisana nokwehliswa kwesijeziso samandla, kodwa esikhulu kakhulu sizokhuphula i-jitter ehlobene nephethini ye-laser.
3. Ukwamukela ukuzwela kusho umkhawulo omncane lapho isiphetho sokwamukela singathola isignali. Uma amandla esignali yesiphetho sokwamukela engaphansi kokuzwela kokwamukela okujwayelekile, isiphetho sokwamukela ngeke sithole idatha.
4. Inani lamandla okukhanya agcwele libhekisela emandleni aphezulu abonakalayo abonakalayo ekugcineni kokwamukela kwemojula ye-optical, ngokuvamile -3dBm. Uma amandla okubona atholiwe emakhulu kunamandla okubona agcwele, amaphutha amancane nawo azokwenziwa. Ngakho-ke, uma imojula ye-optical enamandla amakhulu okudlulisa amehlo ihlolwe ngaphandle kokunciphisa kanye ne-loopback, amaphutha amancane azokwenzeka.
