Abstract
A new synchronous Ramana fiber amplifier is proposed which is pumped at a wavelength around 1.55 μm by output pulses from an erbium-doped fiber amplifier. This ar rangement achieves an output optical peak power exceeding 200 mW and a 3-dB net gain bandwidth of 33 nm around 1.66 p.m. The Raman fiber amplifier is useful for 1.6-μm-band OTDR as it can be used in live maintenance of optical transmission networks.
