SRS induced power depletions of WDM signals by a high power OTDR signal in mobile fronthauls

摘要

We analyze power depletions of DWDM signals caused by a high power OTDR signal in a mobile fronthaul including four optical add/drop nodes in 20 km SMF. We suggest a 1625-nm wavelength or a 1665-nm wavelength as an OTDR signal wavelength to mitigate the stimulated Raman scattering (SRS) induced power depletion of C-band WDM signals.
