 Product description Huatai H1222G FTTH AGC CATV optical receiver, with work bandwidth 47~1200MHz, AGC function, output level Vo=83.5dBμV±0.5dB ( Pin=+3~-7dBm, PAD=1dB ), applies to FTTH fiber to internet, is a low power consume, high performance, high cost performance ONU optical receiver unit for RFTV broadcast network.
H1222G adopt high sensitivity optic receiving tube and Huatai-specialized low noise match circuit, 3.8% modulate, full channel transmit, -8dBm optical power receiving, and the CNR can reach high index 45dB still. H1222G adopt optical AGC, realizing high performance automatic level control ( ALC ).
H1222G optical port mode with following three types optional:
H1222G/NC: RFTV operating wavelength 1260～1620nm.
H1222G/WF: Build-in channel filter, RFTV operating wavelength 1550nm.
H1222G/WD: Build-in CWDM, RFTV operating wavelength 1550nm, pass
wavelength 1310/1490nm, ( Link EPON、GPON ONU ).
