4 Outputs CATV Fiber Optical FTTB Receiver (B9440)

Product Overview

Description

B9440, B9440/WF, B9440/WD
4 outputs high level CATV Fiber optical FTTB receiver

 

 

 

Huatai B9440 CATV Fiber Optical FTTB receiver, 4 output ports, each port output level≥100dBμV when the receiving optical power is -2dBm, 4 outputs with high level, is mainly used in FTTB, FTTN, FTTC.

B9440: RFTV operates in 1210~1600nm wavelength.

B9440/WF: built-in channel filter, RFTV operating in1550nm wavelength.

B9440/WD: built-in CWDM, RFTV operating in 1550nm wavelength, and reach GEPON ONU through 1310/1490nm wavelength.

 

 

1. Extra-low noise (3.8% modulate, -10dBm receive, CNR≥45dB)


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

 

• FTTB, FTTN, FTTC


• HFC
