Four outputs HFC optical Node EN870
1.0 Product Specification
EN-870 Four Output Optical node is a new exploitative bi-direction broadband optical node which combines the current HFC transferring network and international advanced technology. Main part in device adopt module type, it can be assembled in many different ways according to the user’s needs. It’s considered and solved the noise figure problem in the return channels, and sets up good operating status monitor circuit, obligates the standard network and responder ports. It’s an ideal transferring platform for simulated and digital signals to build the large-scale optical network.
