Typically, discrete lumped Raman amplifiers
use separate highly nonlinear fibres as the gain medium, rather than the transmission fibre, to ensure adequate Raman scattering.
This new design of optimum gain flattening performance of Raman amplifier
will be useful for telecommunication networks.
Moreover, we propose IWDM to increase the number of FBG sensors and we employ a Raman amplifier
to increase the sensing signal transmission distance and to improve the signal quality.

The pumping required by Raman amplifiers
is that of counter-propagation, which is preferred in the design and implementation of distributed Raman amplifier
systems (Agrawal, 2002), due to the lower pumping-induced noise coupling on the signal, as well as a less dependence of the gain with the polarization in comparison with the schemes of co-propagation (Neves, Freitas, Almeida, & Calmon, 2003).
A silica fiber Raman amplifier
pumped at a wavelength of 1451.2 nm with pump power 1000 (mW) is designed.
In this paper, we have analyzed the theory and simulated a DWDM network system using a distributed Raman amplifier
pumped in two different directions.
The laboratory test was performed on a 100G/s channel over an ultra low loss optical fiber by using Huawei Marines self-developed enhanced Raman amplifier
(ERPC) and remote optical pumping amplifier (ROPA).
For a discrete Raman amplifier
this parameter is not so relevant.
Jiang "Robust, compact, and flexible heural model for a fiber Raman Amplifier
The most promising alternative to EDFAs are the two types of optical amplifiers that utilize fiber non-linearity for all optical signal amplification purposes: Raman amplifiers
(RA) and fiber optical parametric amplifiers (FOPA).
With todays customers looking for high-capacity connectivity, we see the combination of Xteras high-performing Raman amplifiers
and our advanced transport solutions as a strong fit, states Christoph Glingener, CTO/COO, ADVA.
