We demonstrate experimentally and numerically that the SBS based in-band OSNR monitoring technique can be used for dual polarization signals. We also present novel approach for a drastic enhancement of the sensitivity monitoring range by intentionally adding in-band ASE noise into the signal. Numerical results are provided for 44.6 Gbps DPSK, 44.6 Gbps DQPSK and 112 Gbps Dual Polarization (DP-) QPSK signals, with both 100 GHz and 50 GHz channel spacing scenarios.
