Super Raman Fiber Laser

The Super Raman Fiber Laser from Montreal-based MPB Communications Inc. is a pump source that provides distributed Raman amplification in transmission spans of telecommunications systems via third-order cascaded Raman pumping. Third-order cascaded Raman amplification of C-band signals requires launching high power at 1276 nm, the third-order pump wavelength, and low seed powers at about 1356 and 1455 nm, the intermediate and final pump wavelengths. The 1276-nm power produces high Raman gain for the 1356-nm seed radiation, leading to the generation of high power at 1356 nm. Similarly, the...Read full article
