Optical Node Series : SG4‐RF 100 Module Forward and Return Path RF Module
■The SG4-RF-100 electronics module is the foundation for total segmentation in the SG4000 optical node. Using one RF module per output port, this unique, independent module design provides superior port-to-port isolation performance. By eliminating the single point of failure that typically occurs with one-piece electronics assemblies, the module minimizes service interruptions.
■The module contains all forward and return path diplex filtering within the node, so upgrading return path upper edge from 42 to 85 MHz is as simple as replacing the module. The module's forward path uses Gallium Nitride (GaN) technology to deliver the higher RF output levels required to support fiber deep migration. An integrated JXP-style pad attenuator and RF test point enable technicians to easily monitor and change forward levels. Node station output slope is generated partly by the Flatness and Slope Board (FSB) contained within the RF module. The return path features a -20 dB RF test point followed by a JXP-style pad attenuator. An Ingress Control Switch (ICS) allows technicians to operate the ICS locally using the SG4000 Embedded Plug-in Module (EPIM) or remotely using the DOCSIS status monitor transponder. Finally, a Return-Path Low-Pass Filter (RPLPF) provides additional attenuation of forward path energy at the transmitter input.
