Multi-mode fibers (MMF) are typically used in LAN applications, in links which may reach or exceed 300 meters. Widespread use of electronic dispersion compensation (EDC) for MMF is prompted by the ratification of the 10GBASE-LRM standard. A number of studies have demonstrated the superiority of MLSD for this application. This paper describes an all-DSP single-chip 90nm CMOS MLSD-based EDC transceiver for MMF.
