Lub module hloov 4 inputs channel (ch) ntawm 10Gb / s cov ntaub ntawv hluav taws xob rau 4 CWDM optical signals, thiab multiplexes rau hauv ib qho channel rau 40Gb / s optical kis tau tus mob.Reversely, nyob rau sab receiver, lub module optically de-multiplexes ib tug 40Gb / s input rau 4 CWDM channel signals, thiab converts lawv mus rau 4 channel tso zis hluav taws xob cov ntaub ntawv.

Lub hauv paus wavelengths ntawm 4 CWDM raws yog 1271nm, 1291nm, 1311nm thiab 1331nm raws li cov tswv cuab ntawm CWDM wavelength kab sib chaws txhais hauv ITU-T G694.2.Nws muaj ib tug duplex LC connector rau optical interface thiab 38-pin connector rau hluav taws xob interface.Txhawm rau txo qhov kev cuam tshuam ntawm qhov muag pom hauv qhov ntev-ntev, ib hom fiber ntau (SMF) yuav tsum tau siv rau hauv cov qauv no.
