FTTH CATV Optical Tau Txais
FTTH CATV Optical Tau Txais
4-txoj kev tsim tawm CATV Rov qab mus kho qhov muag txais hluav taws xob yog tsim nyob rau hauv 4-tso zis rov qab txais lub tshuab txais (Philips module). Rau nws txoj siv yooj yim thiab kev ua haujlwm siab, nws tau siv ntawm cov nroog loj thiab nruab nrab-nroog loj hauv kev sib txuas.
Nta
Txhua qhov qauv ntawm no FTTH CATV optical receiver tau txais thiab ua kom nrov zog ntawm cov qauv ntawm nws tus kheej. Nws txais yuav EO PIN thiab PHILIPS laub-rub rub kom loj zog module nrog siab ntsuas thiab zoo C / N.
