Subcarrier modulated transmission of 2.5 Gb/s over 300 m of 62.5-μm-core diameter multimode fiber

We report for the first time the transmission of a 2.5-Gb/s SCM channel over a 300-m length of installed-grade 62.5-μm core-diameter multimode fiber. This result demonstrates that, in a "worst-case" scenario, subcarrier modulation can be successfully used to allow improved quality transmission over multimode fiber links compared with conventional baseband transmission techniques.
