5 Channels Raman Laser Source, Rackmount (RLS-5-R)

Data Sheet

Product Overview

The Optilab RLS-5-R Raman Laser Source is designed as a base unit for Raman amplifier developmental. It can be customized up to 10 different optical pump wavelengths allowing it to meet requirements of different optical networks. The RLS-5-R can be configured to provide optical gain in ultra long-haul DWDM networks, and can also be incorporated into CATV networks to increase the transmission distance of digital and analog channels.  Unlike EDFAs, Raman Amplifiers are based on non-linear effect that occurs during the back scattering wherein the single mode optical fiber in the link itself acts as the gain medium, and is typically installed in the mid-stream of a signal or placed before receivers to increase the optical power level signals. Utilizing a multiple high-power pump laser design, the RLS-5-R provides a wide variety of optical wavelength pump lasers and power levels for customized configuration.
