Chapter 9 OFDM for Multimode Fiber Systems

Multimode fibers (MMFs) are widely used in local area networks (LANs) and optical interconnects. Many of the installed Ethernet backbones are based on MMFs and operate at data rates of approximately 1 Gb/s. A great deal of research is devoted to upgrading 1 Gb/s Ethernet backbones to 10 Gb/s. Because orthogonal frequency-division multiplexing (OFDM) has shown robustness in a variety of wireless channels, it has been adopted in many communication standards1,2 including wireless LAN (Wi-Fi), digital video and audio broadcasting standards, digital subscribed loop (DSL), and Worldwide Interoperability for Microwave Access (WiMAX, or IEEE 802.16). It has been shown in previous chapters that OFDM can successfully ...
