50G PAM4 QSFP28 BIDI kho qhov muag module cov khoom lag luam feem ntau yog rau 5G mid-backhaul daim ntawv thov, tso lub hauv paus muaj zog rau kev lag luam loj siv ntawm 5G bearer tes hauj lwm.
Hauv 5G era, rau cov neeg ua haujlwm, nce bandwidth thiab txo cov nqi tsim kho network yog qhov xav tau tseem ceeb. Tam sim no, 50G PAM4 thev naus laus zis txuag cov khoom siv kho qhov muag kim kim kom ua tiav cov nqi txo los ntawm cov txheej txheem hluav taws xob coding technology, uas yog ib qho ntawm cov lus qhia tseem ceeb ntawm 5G bearer backhaul tes hauj lwm. Nrog rau kev tshaj tawm ntawm 50G PAM4 BIDI cov khoom lag luam, HTF yuav pab txo tus nqi ntawm 5G cov koom tes nrog rau qib tsim nyog thaum siv kev lag luam loj.
Raws li PAM4 (4 Pulse Amplitude Modulation, 4th xaj mem tes amplitude modulation) thev naus laus zis, 50G QSFP ib leeg-fiber bidirectional optical module tau tsim los ua kom tau raws li qhov xwm txheej tam sim no ntawm cov kev xav tau siab bandwidth, cov khoom siv fiber ntau nruj, thiab cov kev xav tau ceev ceev hauv pem hauv ntej network. ntawm 5G network tsim. Siv BOSA cov khoom siv kho qhov muag kom ua tiav ib leeg-fiber bidirectional (BIDI, Bidirectional) kis tau tus mob los txhim kho kev siv fiber ntau; siv PAM4 kev hloov kho thev naus laus zis kom ua tiav 25G cov khoom siv kho qhov muag kom xa 50G cov teeb liab, ua ob npaug ntawm ib tus nqi wavelength; txheeb xyuas qhov kev ua tau zoo los ntawm daim duab qhov muag thiab kev ntsuas kev ntxhov siab kom ua tau raws li IEEE802 Lub 50GE Ethernet ntsig txog cov cai hauv .3cd tuaj yeem ua tau 10 km cov ntaub ntawv xa mus.
