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