3.1. Inkcazo yenkqubo
3.1.1. Xa kujongwa ukwanda komthamo, iyunithi yokususa i-wave demultiplexing yenzelwe ngokwee-waves ezi-8
3.1.2. Ukubalwa kwedatha enikiweyo yokunciphisa intambo ye-optical (ukulahleka koqhagamshelo kunye nokulahleka kokufakwa kufakiwe).
3.1.3. Ubalo lwamandla okukhanya oluhambelanayo:
Icala elinye: Amandla okukhanya angamaza elinye kwimodyuli ye-optical abalwa kwi-0dBm (-2 ～3dBm), andiswa yi-BA aze ancitshiswe yi-OLP, amandla okukhanya efayibha engenayo yi-+4dBm, ancitshiswe ngumgca we-27dBm, i-OLP 2dB incitshiswe, kwaye amandla angena kwi-PA yi--25dBm, Emva kokwandiswa kwe-PA 20dB, amandla amaza elinye yi--5dBm, emva kokususwa kwe-DEMUX, amandla amaza elinye yi--10dBm, okuqinisekisiweyo ukuba kungaphakathi koluhlu lovakalelo lwemodyuli ye-optical;
Ukubuyela umva: Emva kokubala, amandla e-single-wave kwisiphelo sokwamkela yi--10dBm, eqinisekisiweyo ukuba ingaphakathi koluhlu lovakalelo lwemodyuli yokukhanya.
3.1.4. Ubalo lwe-OSNR yenkqubo (elula): OSNR=58+4-27-1-6=28dB≥24dB, ehlangabezana neemfuno zoyilo.
3.2. Iingenelo zesisombululo
3.2.1. Sebenzisa i-DWDM ukongeza iinkonzo ezingama-40 kwintambo enye ye-optical ukuze udlulisele ulwazi, nto leyo egcina kakhulu izixhobo zentambo ye-optical ngelixa iqinisekisa i-bandwidth;
3.2.2. Uzinzo oluphezulu: Olu yilo lwesisombululo lusebenzisa ukhuseleko lwendlela ezimbini ze-OLP 1+1, luxhasa ukutshintshela ngokuzenzekelayo, kwaye luqinisekisa uzinzo lweshishini;
3.2.3. Izixhobo ze-WDM zamkela uyilo lwemodyuli, zahlula ezisebenzayo nezingasebenziyo, kulula ukuzikhulisa, zifuna kuphela ukwandisa ibhodi yenkonzo xa zisanda, ngaphandle kokuphazamisa ishishini elikhoyo.
3.2.4. Ibhodi ye-OTU yamkela uyilo lwe-3R, olunokutshintsha imiqondiso, lukhulise iwotshi kwaye luphinde lubeke ixesha ukuqinisekisa ukuba imiqondiso ayijiki.
3.2.5. Xhasa iinkonzo ezahlukeneyo ukuze ufikelele kwi-SDH, i-PDH, i-CATV, i-Ethernet, idatha yelizwi, njl.njl., ehambelana nezixhobo ezivela kubavelisi abahlukeneyo
3.2.6. Esi sixhobo sinikezela ngombane ongasemva oshushu oyi-1+1, nto leyo ephucula uzinzo lwesixhobo
3.2.7. Unemisebenzi enamandla yolawulo lwenethiwekhi, enokwenza ulawulo lwenethiwekhi ekude, ifezekise ukubekwa kweliso kweshishini kwi-intanethi ngexesha langempela, kwaye iququzelele ukugcinwa
