Equalization of 10 GbE multimode fiber links

This study reports the use of electrical equalization strategies on 10-Gb/s MMF links. Specifically, the use of feed-forward equalization and decision feedback equalization (DFE) methods, to reduce ISI and thereby extend the reach of 10 GbE. Due to the complex behavior of MMF, measured impulse responses are used for a number of fibers. This study demonstrates that 300 m reach is possible for 500 MHz-km fiber, nearly quadrupling the 10 gigabit Ethernet (10 GbE) standard.
