2RU Distributed Raman Sources and Patented Super Raman Pumps

MPB Communications' Raman Pump & Super Raman Pump Sources are an easy to deploy, system-ready solution for high-power Raman optical link enhancement.

Both 1st -order and 3rd-order Raman pump models are available to provide enough power for +28 dB Raman gain, to maximize distributed Raman amplification performance.

Features

Super Raman Pumps
2RU-N-SRP

MPB Communications’ 2RU Super Raman Pumps provide high powers in a single mode output fiber in the
1276-nm range and low power at a 14xx-nm seed wavelength in the same output fiber to provide third-order Raman amplification (MPBC Patent). They have been designed for integration into fiber-optic-telecommunications systems to provide distributed Raman preamplification for signal channels in the C-band.

The 1454-nm single-wavelength models provide sufficiently flat Raman gain over a signal band from 1542 to 1568 nm, while the 1426/1454-nm dual-wavelength models expand the operational range to cover the whole
C-band from 1528 to 1568 nm. All models of Super Raman Pumps are pumped by multi-mode laser diodes, and contain a low-power single-mode seed diode.

Distributed Raman Sources
2RU-N-RFL Raman Pumps

MPB Communication’s Raman Pumps are an easy to deploy, system-ready solution for high-power Raman optical link enhancement. Housed in a low-profile 2RU platform, the unit is self-contained with its own optical, electrical and alarm handling functionality.

Available models can be used alone for distributed Raman amplification to increase system margins in new or existing transmission systems, or they can be combined with other members of MPBs product family (Wavelength Converters, Boosters, Co-Pumps and PreAmplifiers) to provide a complete transmission system.

The RFL Raman pumps are governed by a Fiber Integrity Monitor (FIM) subsystem based on an OSC signal at 1574 nm. In the event of a fiber break or open connector, the FIM subsystem initiates an automatic safety shutdown and then provides automatic restart when connectivity has been restored. If the system does not include a 2RU booster or co-pump (which always include a 1574-nm OSC transmitter), the RFL Raman units for the system must include the optional OSC transmitter.

Multiplexed Laser Diode Pump
2RU-N-LDP Raman Pump

The 2RU-N-LDP-500-1454 provides up to 500 mW at 1454 nm by multiplexing and then depolarizing two 1454-nm laser diodes. It is designed for integration into fiber-optic-telecommunications systems to provide distributed Raman preamplification. The 1454-nm single-wavelength Raman pump provides flat Raman gain over a signal band from 1542 to 1568 nm. The built-in electronics allow the laser diodes to be operated in automatic-power-control (APC) mode via the web-based Craft Terminal.
