In March 2018, the collaboration announced a hybrid EDFA/Distributed Raman Amplifier
achieving record-breaking 120Tb/s capacity on a single fibre.
It was also compared with 1310 nm Raman amplifier
with SOA resulting in wavelength as 1310nm with bandwidth 85 nm .
By adding a Raman amplifier
to a fiber span, signal power loss is decreased and it highly improves the signal-spontaneous beat noise performance.
model in single-mode optical fiber," IEEE Photonics Technol.
To obtain a Raman amplifier
using the optical fiber as a gain medium, the pumping signal and the useful signal must be transmitted on the same fiber, regardless of the direction of propagation; thus, the SRS is produced.

Besides, there are several types of amplifiers such as SOA, EDFA, and Raman amplifier
that have been introduced to encounter the attenuation effects.
In this model, we used a distributed Raman amplifier
with different two pump schemes are forward and backward pumping.
To boost the reach of GPON, Lee and his team use a device called a Raman amplifier
Based on Huaweis advanced 100G technology, enhanced raman amplifier
(ERPC) and remote optical pump amplifier (ROPA), Huawei Marine achieved a major breakthrough in unrepeatered submarine cable system transmission in April 2016, with a transmission distance of 627km but has now increased this transmission distance further.
Based on Huaweis advanced 100G technology, Enhanced Raman Amplifier
and ROPA (remote optical pump amplifier), Huawei Marine has achieved a major breakthrough in unrepeatered submarine cable system transmission.
To investigate the performance of SOA and discrete Raman amplifier
a simulation model of a 10 Gbit/s 16 channel DWDM transmission system with none-return-to-zero encoding technique, intensity on-off keying modulation format, and 50 GHz channel spacing has been introduced.
