Demonstration, using sliding-frequency guiding filters, of error-free soliton transmission over more than 20 Mm at 10 Gbit/s, single channel, and over more than 13 Mm at 20 Gbit/s in a two-channel WDM

Abstract

By transmitting trains of 214 bit pseudorandom words in a recirculating loop containing strong, sliding-frequency guiding filters, ‘error-free’ (measured BER ≤, 10−9) soliton transmission at 10 Gbit/s, single channel, and at 20 Gbit/s in a two channel WDM is demonstrated, over paths as great as 20 000 km and 13 000 km, respectively.
