Abstract :
For short-haul optical networks, multimode fiber is ideal in regards to ease of use and cost-effectiveness. Unfortunately, modal dispersion in the fiber, can lead to severe intersymbol interference. A multisegment photodetector is used to perform spatially resolved equalization of the channel response. We demonstrate, through measured impulse response and bit error rate, robust performance to variations in channel condition.
