NTT Technical Review, Vol. 15, No. 9, Sept. 2017
In this field trial, all-Raman optical amplification technolo-gy*1 was employed in transmission line repeaters, and 400-Gbit/s signals were transmitted in multiple bands at the same time.
Experiment and Field Test of Raman Amplifier Based on 400G
The performance optimization of Raman amplifier in 400G system is analyzed. Compared with the test in real fiber link, the quality of actual fiber link has a greater influence on Raman amplifier.
