Product DescriptionH9122, the operating bandwidth of 47~862MHz,
Products with high sensitivity optical receiver tube and Huatai
special low noise matching circuit,Whether used in analog
television or digital television, have high reception sensitivity
and excellent intermodulation distortion index. is a low power,
high performance, cost-effective triple play, FTTH CATV optical
receiver.H9122 for Analog TV, in Pin =-10dBm when, Vo ≥ 69dBμV, CNR
≥ 45dB.H9122 for Digital TV, in Pin =-15dBm when, Vo ≥ 62.7dBμV,
MER ≥ 36.8dB.H9122 for Digital TV, in Pin =-20dBm when, Vo ≥
53.1dBμV, MER ≥ 29.4dB.Triple play, fiber to the home, using the
H9122 can save a lot of optical fiber amplifier power resources.
For operators, can greatly reduce the cost of building the
network.Product Features1. Extra-low noise(3.8% modulate, -10dBm
receive, CNR ≥ 45dB)2. Wide dynamic receiving optical power range:
within Pin=-15, MER≥36.8dB3. Applicable GPON, EPON, compatible with
any FTTx PON technology4. Can save a large number of optical power
resource, greatly reduce the network configuration cost5. In the
range of 47~862MHz, all have good flatness (FL ≤± 0.75dB)6. Metal
shell, supply safeguards to opto-electrical sensing device7. High
output level can supply for many users8. Low power consumption,
high cost performanceMain Application1. CATV FTTH2. Integration of
three networks3. FTTH PONTechnical
