Raman Amplifier in One 1U Rack Mount, 12dB, LC/UPC

Raman Amplifier provides remote amplification by activating the Stimulated Raman Scattering (SRS) phenomenon along the transmission fiber. It's often used as preamplifier or repeater to enhance the performance of EDFAs in dense wavelength division multiplexing (DWDM) systems. It also has a better optical signal-to-noise ratio than EDFA amplifiers, and flat gain across all the C-band wavelengths range.

Raman amplifiers have also proven useful for all technology choices that can be used to deploy 100G and above.

How Hybird Raman Amplifier and EDFA Work

Raman pumping with the high power amplifies the emission in the line before its input to EDFA and decrease an effective noise factor of the amplifier. Due to lower noise factor, it is possible to achieve larger distances between amplifiers and decrease network operating costs.

Extending Transmission Distances without Signal Regeneration by Raman Amplifier

Raman amplifier is found critical and effective in complementing the EDFA for transmission distance expansion. Using stimulated Raman scattering to provide distributed gain over a span of optical fiber, the transmission distances up to 200km, which provides the most economical and reliable solution for long transport spans.
