## Abstract In this paper, a 38βnm wideband gainβflattened distributed Raman amplifier utilising two pump wavelengths is experimentally demonstrated. The pump combination of 1430 and 1456 nm with 26βnm spacing has enabled a gain flatness of less than 1.1 dB at a Raman onβoff gain of 10 dB. The flat
The governing equations of optical fiber Raman amplifier with broadband pumps in the steady state are systems of uncountable nonlinear ordinary differential equations (NODE). In this paper, the Moment method is used to reduce the uncountable system of NODE to a system of finite number of NODE. This
