POLARIZATION MULTIPLEXING WITH SOLITONS

摘要

The single-wavelength bit-rate capacity of an ultra long distance soliton transmission system is increased by using a combination of polarization and time-division multiplexing. More specifically, two streams of differently (preferably orthogonally) polarized solitons are interleaved (time division multiplexed) at a transmitter, and later separated at the receiver to recover both data streams. The system operates at speeds of up to 7.5 GHZ and provides very thorough separation of channels required for 10<-><1><2> error rates at distances of up to 9000 km or more.
