3.1.Inkcazo yenkqubo
3.1.1.Ukuqwalasela ukwandiswa kwamandla, iyunithi ye-wave demultiplexing iyilwe ngokuhambelana namaza asi-8
3.1.2.Ukubalwa kwedatha enikezelweyo yokunciphisa intambo ye-optical (ukulahleka koqhagamshelwano kunye nokulahlekelwa kokufaka kufakiwe).
3.1.3.Ikhonkco lokubala amandla okukhanya:
Unidirectional: I-single-wave amandla akhanyayo emodyuli ye-optical ibalwa kwi-0dBm (-2～3dBm), inyuswe yi-BA kwaye igxininiswe yi-OLP, amandla angenayo e-fiber optical + 4dBm, athotywe ngumgca we-27dBm, i-OLP 2dB iyancipha, kunye namandla angena kwi-PA yi -25dBm , Emva kwe-PA 20dB yokukhulisa, amandla ombane omnye-5dBm, emva kwe-DEMUX de-wave, amandla angamaza angama-1 -10dBm, aqinisekisiweyo ukuba angaphakathi kuluhlu lovakalelo lwe imodyuli yokubona;
Ukubuyisela umva: Emva kokubala, amandla amaza elinye ekupheleni kokufumana yi-10dBm, eqinisekisiweyo ukuba ingaphakathi kobuntununtunu bemodyuli ye-optical.
3.1.4.Indlela yokubala ye-OSNR (elula): OSNR=58+4-27-1-6=28dB≥24dB, edibana neenkcukacha zoyilo.
