Product Description
CATV FTTH Optical Receiver
Huatai H9122 product series, CATV FTTH Optical Receiver ,47~862MHz operate bandwidth, output level Vo=82dBμV (Pin=- 2dBm), suitable for FTTH optical fiber access network, which is a low power consumption, high performance, and excellent cost performance RFTV broadcast network ONU(Optical network unit).
This series product adopts high sensitivity receiving tube and Huatai special low noise matching circuit. Under 3.8% modulation, when transmitting in full channels and with receiving power of -10dBm, the CNR can still reach high index of 45dB. Therefore, if adopting H9122, it is only need very low optical power to reach 45dB CNR required by the user.
H9122 optical port have following three modes:
H9122/NC: RFTV operates in 1210~1600nm wavelength.
H9122/WF: built-in channel filter, RFTV operating in1550nm wavelength.
H9122/WD: built-in CWDM, RFTV operating in 1550nm wavelength, via 1310/1490nm wavelength, ( casemate EPON,GPON ONU ).
Product feature
