Abstract
In optical multiple-access networks using subcarrier multiplexing (SCM), performance degradation due to beat noise is a severe problem. In this paper, the authors propose a beat-noise-free SCM optical multiple-access network using subcarrier multiplexing repeaters. Low-cost and long-distance systems are possible using the proposed network. Furthermore, fundamental characteristics have been estimated. Results indicate that in a wide-area monitoring system, 20 local nodes (LNs) with Fabry-Perot (FP) LDs and 200 LNs with DFB LDs can be connected, respectively.
