  • Abstract
    The gain variation of distributed Raman amplifier (DRA) for wavelength-division-multiplexing (WDM) system is demonstrated. Experiments on a six-channel WDM system with DRA show the gain variation of less than 0.05 dB under the situation of dropping channels. It is found that the gain variation arising from the add/drop channels and the change of input signal powers has been improved tremendously in DRA system than EDFA system. Therefore, unlike EDFA system, DRA system requires no technique of gain clamping.
