0.1-nm slim bandwidth transmission of a 2.5-Gbit/s spectrum-sliced incoherent channel using an all-optical bandwidth expansion technique at the receiver

Summary form only given. In this paper, we present a simple all-optical technique to reduce the optical bandwidth of the spectrum-sliced incoherent WDM channels. To minimize the dispersion penalty, the optical bandwidth is kept to a minimum value during the transmission. At the receiver side, we expand the signal bandwidth using the fiber four-wave mixing, which reduces the beat noise and restores the signal-to-noise ratio to a desired value.
