By using cw laser diodes operating at 1.26 and 1.34 μm, the cross talk caused by stimulated Raman scattering in a 21-km single-mode fiber was measured to be −25.2 dB at a pump-power level of 1.0 mW. The Raman-gain coefficient was calculated to be 0.57 × 10−11 cm/W, which is in good agreement with previously reported values measured with high-power pulsed lasers.
