FTTH CATV optical receiver

FTTH CATV optical receiver

Product description:

H9122, output level ≥ 82dB μV when the receiving optical power is -2dBm, is mainly used in FTTH. As RFTV broadcast network's RX unit, it is a kind of high index, Low power consumption and high cost performance RFTV optical receiver.

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 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, reach GEPON ONU through 1310/1490nm wavelength.

Product feature:

  • Extra-low noise (3.8% modulate, -10dBm receive, CNR ≥ 45dB)
  • All receiving optical power in the range of +3dBm to -12dBm has good linearity
  • In the range of 47~862MHz, all have good flatness (FL ≤± 1.0dB)
  • Metal shell, supply safeguards to opto-electrical sensing device
  • High output level can supply for many users
  • Low power consumption, high cost performance

Main application:

  • FTTH

Status indicator:

Input optical power status indicator:

  • ≤-13dB                                 LED off
  • +3dBm ~ -12dBm                  Green
  • +3dBm                                 Red
