| Summary: | In this letter, we present a report on the experimental
validation of double-pass discrete Raman amplifier (DRA)
limitation for large signals. It has been proven that the limitation
of double-pass Raman amplifier for large signals is due to stimulated
Brillouin scattering (SBS) even though with a modulated
signal at 10-Gb/s data. The multichannel amplification shows that
this limitation can be relaxed due to energy distribution among
the channels, the SBS threshold is enhanced. An average gain
of 19.2 dB is obtained in four-channel amplification without any
significant SBS effects. The double-pass DRA is found suitable for
large signals to be deployed in wavelength division multiplexing
systems. |
