Raman Amplifier in One 1U Rack Mount


Raman Amplifier provides remote amplification by activating the Stimulated Raman Scattering (SRS) phenomenon along the transmission fiber. It's often used as preamplifier 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.

Product Highlights

Fully Independent Rack Mountable 1U
  • Gain spectrum depends on pump wavelength, extending optical signals beyond EDFA amplifier reach
  • Amplification medium is transmission fiber itself, making it possible to extend repeaterless transmission distance
  • Safety features automatically detect open links and stop Raman pump power to reduce equipment or eye damage danger

Raman Amplifier for Long-haul DWDM Transmission with Optimized OSNR

The use of Raman amplifiers reduce non-linear distortion and provides an optimized signal-to-noise ratio, therefore make the link become more robust, with more margin available for future repairs or changes along the link.

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.

Questions & Answers
  • Q:

    What is the difference between forward Raman Pump and Reverse Pump? By Mark on 11/14/2019

    A:

    The difference between them is the different placement, the forward pump is placed at the transmitting end and the reverse pump is placed at the receiving end. And they can be judged by the direction of the pump light. If the pump light and the signal light are in the same direction, it's forward pump; Otherwise, it's reverse pump. By FS on 11/14/2019
