Le mveliso iguqula idatha yokufaka umbane ye-4-channel 10Gb/s ibe yi-CWDM optical signals (light), nge-4-wavelength Distributed Feedback Laser (DFB) array eqhutywa yi-4-wavelength Distributed Feedback Laser (DFB). Ukukhanya kudibaniswa ngamalungu e-MUX njengedatha ye-40Gb/s, isasazeka kwi-transmitter module esuka kwi-SMF. I-receiver module yamkela i-40Gb/s CWDM optical signals input, kwaye iyisuse kwi-multiplexes kwiitshaneli ezine ze-10Gb/s ezine-wavelength eyahlukileyo. Ukukhanya ngakunye kwe-wavelength kuqokelelwa yi-discrete avalanche photodiode (APD), ize ikhutshwe njengedatha yombane emva kokuba ikhuliswe kuqala yi-TIA ize emva koko ikhutshwe yi-post amplifier.

II-HUAQ40EYenzelwe ukuba isebenzise i-form factor, i-optical/electrical connection kunye ne-digital diagnostic interface ngokwe-QSFP Multi-Source Agreement (MSA). Yenzelwe ukuhlangabezana neemeko zokusebenza zangaphandle ezinzima kuquka ubushushu, ukufuma kunye nokuphazamiseka kwe-EMI. Le modyuli inika ukusebenza okuphezulu kakhulu kunye nokuhlanganiswa kweempawu, okufikelelekayo nge-interface ye-serial yeengcingo ezimbini.

I-HUANET HUAXDI-xx1XL-CD80 yi-DWDM XFP Transceiver ebonisa uzinzo oluhle kakhulu lwe-wavelength, ixhasa ukusebenza kwitshaneli ye-100GHz, imodyuli engabizi kakhulu.
