100km Quasi-lossless Fiber-optic Transmission with a Novel Cascaded Random Raman Fiber Laser

Ultra-long distance (100km) quasi-lossless fiber-optic transmission is experimentally performed by using the 3
^rd
-order Raman amplification pumped by a novel 1280nm cascaded random Raman fiber laser, which is the longest quasi-lossless transmission system reported to date.
