%X We propose and experimentally demonstrate a new method to
extend the range of Brillouin optical time domain analysis (BOTDA)
systems. It exploits the virtual transparency created by second-order Raman
pumping in optical fibers. The idea is theoretically analyzed and
experimentally demonstrated in a 50 km fiber. By working close to
transparency, we also show that the measurement length of the BOTDA
can be increased up to 100 km with 2 meter resolution. We envisage
extensions of this technique to measurement lengths well beyond this value,
as long as the issue of relative intensity noise (RIN) of the primary Raman
pump can be avoided.
