FTTH 47~1000MHz CATV Mini Optical Receiver (H9122)

Product Overview

Description

H9122

FTTH 47~1000MHz  CATV Mini Optical Receiver

 

 

 

Huatai H9122  catv mini optical receiver series, 47~1000MHz 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.

 

1. Extra-low noise(3.8% modulate, -10dBm receive, CNR ≥ 45dB)


2. All receiving optical power in the range of +3dBm to -12dBm has good linearity


3. In the range of 47~862MHz, all have good flatness (FL ≤± 1.0dB)


4. Metal shell, supply safeguards to opto-electrical sensing device


5. High output level can supply for many users


6. Low power consumption, high cost performance
