Four outputs FTTB CATV optical receiver
Model: B9428, B9428/WF, B9428/WD
Product description:
B9428 product series, 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).
This series of 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 B9428, it is only need very low optical power to reach 45dB CNR required by the user.
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.
