Abstract:
The Pilot-tone-assisted crosstalk (PT-XT) monitoring scheme is demonstrated in MDM systems with only the low-bandwidth photodetector (PD) and simplified feature-extraction operations. The monitoring accuracy, characterised by the coefficient of determination R2, is experimentally achieved over 0.988 for a three-mode scenario.
