Abstract
We demonstrate an optical transmission link capable of 50- Gb/s through 500 meters of multimode fiber. The aggregate bit rate is carried by 10 parallel wavelength channels, where the individual channel speed is 5-Gb/s. The source of the optical signal is an novel hybrid OTDM-WDM system based on a multi wavelength mode-locked semiconductor diode laser. The performance of the link is evaluated using bit-error rate (BER) analysis. Eye diagrams of the received optical signal yield a BER of 5 X 10-10. Spectral and temporal traces show robust pulse transmission and the potential for further increase in the aggregate bit rate.
