High-speed transmission in multimode fibers

Overview was given on MMF applications, standards and MMF characterization - Reach, speed and capacity extension techniques were reviewed and discussed GI-MMF-Systems - 40 Gb/s and 100 Gb/s line rates will be realized by space division multiplexing - Lasers, fibers and receivers show up for 40 Gb/s serial systems for more than 400 m transmission distance on a single wavelength - WDM, OFDM and SCM can contribute to extend capacity times distance product to reach several Tb/s·km - Main advantage of high coupling tolerances must be maintained! POF-Systems - 40 Gb/s transmission over 100 m GI-POF and GI-PF-POF is feasible - Higher order modulation formats, WDM, OFDM, SCM and electronic equalization techniques are applied to increase capacity times distance product
