PL3000A optical segmentable node is designed for fiber deeper HFC networks.
It has two high level RF output ports. Each high level RF output port can be split into two lower level output ports.
All attenuation and equalization changes will be set using standard JXP type pads. Reverse traffic can be combined and routed to a DFB return transmitter modules. Bi-directional TPs allow the operator for monitor and injection at one TP port. Add Local Injection function at RF input port. Add input EQ at the output of optical receiver.
PL3000A optical segmentable node will be capable of field upgrade from a PL3100A Amp to a optical node. It will be field upgradable from a forward only to a forward and return path product.PL3000A segmentable nodeis flexible for specific network needs because of the adoption of selectable optical connector, strand mounting, international frequency split.
