 Product description Huatai P9428, the operating bandwidth of 47 ~ 862MHz, is a low power, high performance, cost-effective triple play, FTTH CATV optical receiver. Products with high sensitivity optical receiver tube and Huatai special low noise matching circuit..
P9428 for Analog TV, in Pin =-9dBm when, Vo ≥ 79dBμV, CNR ≥ 44dB.
P9428 for Digital TV, in Pin =-16dBm when, Vo ≥ 74dBμV, MER ≥ 34dB.
P9428 for Digital TV, in Pin =-20dBm when, Vo ≥ 66dBμV, MER ≥ 27dB.
Triple play, fiber to the home, using the P9428 can save a lot of optical fiber amplifier power resources. For operators, can greatly reduce the cost of building the network.
P9428optical port mode with following three types optional:
P9428 :operating wavelength 1260~1620nm.
P9428/WD: Built-in CWDM, suitable for single-fiber triple wavelength system, CATV
operating wavelength 1550nm, passwavelength 1310/1490nm, can conveniently connect the ONU of EPON, GPON.
P9428/WF: built-in 1310/1490nm filter,suitable for single-fiber triple wavelength
system, CATV operating wavelength 1550nm.
Product feature  Extra-low noise(3.8% modulate, -9dBm receive, CNR ≥ 44dB) Wide dynamic receiving optical power range: within Pin=-16, MER≥34dB Can save a large number of optical power resource, greatly reduce the network configuration cost
