Abstract
By using a signal bandwidth expansion combined with a distributed Raman amplifier and an EDFA, we have achieved WDM transmission over 7,221 km at 1.22 Tbit/s in the L-band alone. The scheme seems to be more practical because it has relatively low loss gain equalization, the shorter wavelength OSNR improvement, and effective gain tilt compensation.
