Abstract
If a singlemode fibre is monitored with an optical time-domain reflectometer (OTDR) at 1.65 µm, stimulated Raman scattering causes nonlinear loss for a transmission channel at 1.55 µm. Calculations show that in some cases the permitted OTDR pulse power is limited to a few milliwatts.Keywords
