NRZ and RZ Pulse Forms in WDM Systems with Distributed Fiber
Minhui Yan and others from Shanghai Jiao Tong University, China, discuss the theory behind low-noise fiber Raman amplifiers and how these amplifiers have different effects on NRZ and
Raman amplification
For submarine applications, Raman amplification minimizes the number of underwater repeaters, enhancing reliability and cost-efficiency, while in terrestrial setups, it facilitates ultra-long-haul links
Comparison of EDFA and Raman Amplifiers Effects on RZ and NRZ
In this paper, the attempt is done to improve the capacity and performance of semiconductor optical amplifier, Raman and erbium-doped fiber amplifier (EDFA) amplifiers used in optical networks.
Raman Amplifier
The Raman amplifier makes use of stimulated Raman scattering (SRS) within the fiber, which transfers the energy of higher-frequency pump signals to lower-frequency signals.
Comparison of EDFA and Raman amplifiers effects on RZ and
It is found that the employment of Raman amplifier and NRZ technique, would allow establishing a DWDM network to have the same performance quality as that of 80km network with EDFA inclusion.

Comparison of EDFA and Raman Amplifiers Effects on RZ and NRZ Encoding Techniques in DWDM Optical Network with Bit Rate of 80 Gb/s
Comparison of EDFA and Raman amplifiers effects on RZ and NRZ
Such a situation will cause errors in detection of signals at the receiver end. So, to circumvent this problem, use of optical amplifiers is required. Erbium-doped fiber amplifier (EDFA)
