1RU Product Line

1RU Raman Pumps

MPB 1RU LDP Raman PumpBased on MPBC’s LDP Series of multiplexed laser diode Raman pump sources, the 1RU-Raman line provides distributed Raman amplification in optical transmission fibers.

The unit can be used alone to increase system margins in existing transmission systems (to compensate for increases in span loss due to aging or to allow increases in capacity) or can be combined with other members of MPBC’s 1RU product family (Wavelength Converters, Amplifiers and Preamplifiers) to provide a complete transmission system.

The 1RU Raman pump units include a fiber integrity monitor subsystem which initiates an automatic safety shutdown in the event of a fiber break. Operational control and status and alarm monitoring are via a CRAFT terminal interface.
