MRV's Raman Amplifiers Enable Ultra Long-Haul DWDM

MRV Communications released new ultra long-distance optical Raman amplifier modules for its Lambda Driver DWDM transport platform. MRV's new Raman amplifiers utilize stimulated Raman scattering to create optical gain. The new amplifiers increase the single span reach of an optical signal by more than 50 km over traditional Erbium Doped Fiber Amplifier (EDFA)-based alternatives by improving the optical signal-to-noise ratio in amplified long-haul networks.



MRV's EM1600-OAR Raman amplifier family consists of three modules that offer 10dB, 12dB and 15dB of maximum optical gain over G652 fiber. The amplifiers provide flat response for the entire C-band with the optional ability to be configured to other wavelength ranges.



MRV supports several protection techniques including automatic optical shut down upon detection of fiber break or open connector.
