Abstract
1. Prologue An FDM (Frequency Division Multiplexing) system is a very promising system in that it is only feasible by Photonics. It utilized enormous bandwidth of lightwave and is independent of transmission methods and bitrate. This system seems more suitable for the coming broadband age than ATM-based systems because in future they will provide us with an infrastructure for more flexible and lower cost telecommunication networks.
