CATV FTTH Optical Receiver CSP-1010

CATV FTTH Optical Receiver CSP-1010
  • Summary
  • Features
  • Advantage
    FTTH Optic receiver CSP1010 with 2 output ports, output level ≥ 82dB μ V when the receiving optical power is -2dBm,  Low power consumption and high cost performance RFTV optical receiver.Adopts high sensitivity receiving tube and special low noise matching circuit. when transmitting in full channels and with receiving power of -10dBm,the CNR can still reach high index of 45dB. Therefore, if adopting CSP1010, it is only need very low optical power to reach 45dB CNR required by the user.

    1.Very low noise(3.8% modulation, -10dBm receive, CNR≥45dB).
    2.Receive optic power in the range of +3dBm to -12dBm, all have good linearity.
    3.In the rang of 47~862MHz, all have good flatness property(FL≤±1.0dB). .
    4.Metal shell, supply safe guards to opto-electrical sensing device
    5.High output level can supply for many users
    6.Low power consumption, high cost performance
