SQON-I Inversed Optical Node

Query


SQON-I Inversed Optical Node is a two-way node with 1000 MHz bandwidth. It is specifically designed for use in HFC expansion networks. It provides excellent performance with high reliability and a user-friendly layout. It contains a 1550nm transmitter with RF input AGC function and a 4-way optical passive splitter for system expansion in the forward path, and also contains a 1310nm return receiver with a 4-way optical passive combiner in the return path. It has a high return RF output level for uplink injection. Plug-in attenuator and equalizer for easy adjusting RF level and output slope.
