| Abstract: | A two-channel lightwave system using differential frequencydeviation multiplexing (DFDM) is presented. Both 90Mbit/s channels are differentially detected using a fibre interferometer. The performance is independent of the absolute optical frequencies and received state of polarisation. Interchannel interference results in a 1 dB penalty for channel separations of 700 MHz. |
