Cov tsoos100G optical modulesiv 4x25G optical channels, thiab 4 optical channels paub 100G kis tau tus mob los ntawm wavelength division multiplexing lossis channel parallel mode. Qhov no yog siv PSM4 thev naus laus zis. Txhua lub channel yuav tsum muaj cov khoom sib kis thiab txais cov khoom sib cais, uas ua rau muaj kev xav tau siab ntawm kev siv hluav taws xob, qhov chaw teeb tsa thiab tus nqi ntawm cov khoom siv kho qhov muag.
100G ib leeg-wavelength kho qhov muag module siv DSP los hloov 4 raws ntawm 25G hluav taws xob teeb liab rau hauv ib lub wavelength100GPAM4 optical signals kom ua tiav cov ntaub ntawv xa mus. Tus naj npawb ntawm lub teeb xa tawm thiab tau txais cov khoom raug txo los ntawm 4 mus rau 1, txo qis qhov nyuaj ntawm optical hauv qhov kho qhov muag module. Vim qhov txo qis ntawm cov khoom siv, tus nqi txo qis heev (tus nqi ntawm cov khoom siv kho qhov muag suav txog li 60 feem pua ntawm cov nqi ntawm tag nrho cov khoom siv kho qhov muag).
