3.1.Kev piav qhia ntawm qhov program
3.1.1.Xav txog qhov muaj peev xwm nthuav dav, yoj demultiplexing chav tsev yog tsim raws li 8 nthwv dej
3.1.2.Kev suav cov ntaub ntawv muab rau lub attenuation ntawm lub optical cable (kev twb kev txuas poob thiab insertion poob yog suav nrog).
3.1.3.Txuas optical zog xam:
Unidirectional: Lub zog ib leeg-yoj luminous ntawm lub optical module yog xam ntawm 0dBm (-2～3dBm), amplified los ntawm BA thiab attenuated los ntawm OLP, lub incoming fiber optical zog yog +4dBm, attenuated los ntawm kab 27dBm, OLP 2dB attenuated, thiab lub zog nkag mus rau PA yog -25dBm, Tom qab PA 20dB amplification, ib leeg-yoj lub zog yog -5dBm, tom qab DEMUX de-wave, ib leeg-yoj fais fab yog -10dBm, uas yog guaranteed nyob rau hauv lub rhiab heev ntau yam ntawm lub optical module;
Rov qab: Tom qab xam, lub zog ib leeg ntawm qhov kawg tau txais yog -10dBm, uas tau lees tias nyob rau hauv qhov rhiab heev ntawm qhov kho qhov muag module.
3.1.4.Kev suav OSNR (yooj yim): OSNR = 58 + 4-27-1-6 = 28dB≥24dB, uas ua tau raws li cov qauv tsim.
3.2.Kev daws qhov zoo
3.2.1.Siv DWDM rau multiplex 40 cov kev pab cuam ntawm ib qho khoom siv kho qhov muag rau kev sib kis, uas txuag tau nyiaj ntau ntawm cov khoom siv kho qhov muag thaum ua kom cov bandwidth;
3.2.2.Kev ruaj ntseg siab: Qhov kev daws teeb meem no siv OLP 1 + 1 dual txoj kev tiv thaiv, txhawb kev hloov pauv tsis siv neeg, thiab ua kom muaj kev lag luam ruaj khov;
3.2.3.WDM cov cuab yeej siv cov qauv tsim, cais cov nquag ua haujlwm thiab tsis muaj zog, yooj yim rau kev nthuav dav, tsuas yog yuav tsum tau nce lub rooj tsav xwm pabcuam thaum nthuav dav, tsis cuam tshuam rau kev lag luam uas twb muaj lawm.
3.2.4.Lub Rooj Tswjhwm Saib OTU tau txais kev tsim qauv 3R, uas tuaj yeem hloov kho lub teeb liab, nthuav lub moos thiab rov ua lub sijhawm kom ntseeg tau tias lub teeb liab tsis cuam tshuam.
