A 2-Channel System Demonstration of Differential Frequency-Deviation Multiplexing
01 January 1987
In this paper we present a two-channel demonstration of differential frequency-deviation multiplexing (DFDM). Two cleaved coupled-cavity (C sup 3) lasers are frequency modulated, by differentially-encoded 90 Mb/s data, and their outputs are combined in a 3dB fiber coupler.
