Four outputs FTTB CATV optical receiver

Product description
AITC B9428, 4 output ports, each port output level ≥ 88dB μ V when the receiving optical power is -5dBm, is mainly used in FTTH, FTTN, FTTC. As RFTV broadcast network's RX unit, it is a kind of high index, low power consumption, and high cost performance RFTV optical receiver.
The product built-in RF inter-stage gain adjustment. All receiving optical power in the range of +3dBm to -12dBm has good linearity. According to different receiving optical power, the user can choose high CNR and suitable output level.

B9428: RFTV operates in 1210~1600nm wavelength.
B9428/WF: Built-in channel filter, RFTV operating in1550nm wavelength.
B9428/WD: Built-in CWDM, RFTV operating in 1550nm wavelength, reach GEPON ONU through 1310/1490nm wavelength.

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