China CATV Outdoor Waterproof Optical Node

1 forward path optical receiver module+1 return path optical transmitter module+ 1 thernet transponder
module and 1 switching power supply module.

2. Performance Characteristics

1. The forward path optical receiving part adopts advanced optical AGC technology, the input optical
power range extended to-8~+2dBm.

2. Forward path optical receiving part: RF operating bandwidth extended to 1GHz, each way maximum
output level is up to 112dBμV.

3. Both equalizer and attenuator are built by fixed attenuator in order to manage accessories expediently.

4. Built-in perfect condition monitoring circuit and support Ethernet transponder, remote management
by the NMS.

5. Built-in tri-state gate switch circuit in the return path. Three states passthrough, -6dB and OFF can
be remote set by network management transponder.
