High-bit-rate ETDM transmission systems

摘要: Publisher Summary This chapter is an up-to-date review of high-speed transmission using electronic time division multiplexing (ETDM), a time-honored approach for upgrading system capacity. The emphasis on 100-Gb/s bit rate and beyond, as 40-Gb/s systems are already being deployed Ethernet (100 GE) expected to be the next dominant transport technology. throughput in optical networks increasing inexorably, backhauling traffic generated by triple-play video-on-demand services main drivers. In wavelength (WDM) network commonly used frequency grid either 50 or 100 Ghz, which will have major impact high-bit-rate ETDM approaches can applied. has principle reputation low-cost Besides advantages serial approach, compete with WDM regarding cost terminal equipment. A basic treatment technology presented chapter, followed description concepts systems. requirements components state-of-the-art technologies then examined, overview ultra-high-speed experiments presented. Finally, prospects various rendering cost-effective GE contemplated.
