A View of Next Generation Optical Communication Systems-possible future high-capacity transport implementations

摘要

Possible implementations of next generation high-capacity Transport are presented and associated technical challenges are discussed. From the expected spectral efficiency of conventional modulation formats and based on substantial practical system integration experience, it is estimated that a practical transmission capacity for a single 1000 km fiber is between 2 and 5 Tb/s, assuming a 10 THz transmisison window.
