Abstract

Closed-form formulae have been analytically derived to estimate crosstalk due to stimulated Raman scattering (SRS) in a multipumped, broad, and flattened gain distributed Raman amplifier (DRA). The derived formulae are applied to study the crosstalk due to SRS in a multipumped DRA having different pumping configurations. System bounds for a typical wavelength division multiplexing sys tem employing DRA have been evaluated theoretically. Performance of DRA for other parameters such as wavelength separation, input signal power, and bit rate of the system has also been investigated.
