Chapter 22. DM4000 GPC-OAP
22.1. Overview
DM4000 GPC-OAP is an active pre-amplifier based on erbium doped fiber (EDF). The module amplifies
attenuated optical signals, making possible its detection by receptor. DM4000 GPC-OAP allows extension
of optical loop up to 10 Gbit/s.
It can be managed by host equipment or directly. If the configuration jumper is on "AUTO" position, front
serial interface is disabled and the configuration is executed by equipment. If the jumper is on "FORCED"
position, the panel serial interface allows amplifier module’s direct local configuration.
