Product Overview
Description
Four outputs CATV FTTB optical receiver
B9428
Product description
Huatai B9428 Four Outputs CATV FTTB Optical Receiver , 47~862MHz operate bandwidth, output level Vo=88dBμV (Pin=-2dBm), suitable for FTTP optical fiber access network, which is a low power consumption, high performance, and excellent cost performance RFTV broadcast network ONU(Optical network unit).
The product built-in RF inter-stage gain adjustment. All receiving optical power in the range of +3dBm to -12dBm has good linearity. According to different receiving optical power, the user can choose high CNR and suitable output level.
B9428 optical port have following three modes:
B9428/NC: RFTV operates in 1210~1600nm wavelength.
B9428/WF: built-in channel filter, RFTV operating in1550nm wavelength.
B9428/WD: built-in CWDM, RFTV operating in 1550nm wavelength, reach GEPON ONU through 1310/1490nm wavelength.
Product features
