GIP Technology Raman pump units (RPUs) are specifically designed for distributed Raman application, using the entire transmission fiber as a gain medium, can achieve to improve the OSNR and other system performance greatly. These series incorporate excellent pump power combiner and pump/signal multiplexer to produce highest Raman gain in the most conversion efficiency. These series are suitable used in ultra-long haul and wide bandwidth DWDM systems of core network and Metropolitan network.

This model is offered as C-band version in the counter-propagating configuration.

The compact stand-alone type, it not only can be embedded in the EIA 19 and 23-inch rack-mounted chassis, but also can be placed on the desk.

In addition, these units also provide a user-friendly status monitoring via an LCD display, LED indicators, and various communication interfaces (RS232 and SNMP).
