Nonlinearity-Tolerant Fiber for Greater Transmission Capacity in Optical Communications
Higher transmission capacity Nonlinearity-tolerant Shifts burden of compensation to linear issues that are more easily solved
Long-haul optical communications
Single-mode fiber has been the choice in long-haul fiber transmission for its dispersion control. UCF researchers now propose using multi-mode fibers to increase nonlinearity tolerance, and with it, a new approach to combating fiber transmission impairments including dispersion and nonlinearity. Multi-mode fibers reduce nonlinearity compared to single-mode fibers by increasing the mode field diameters of all modes involved. This shifts the burden from compensating for nonlinearity to the more solvable problem of managing dispersion, which can be compensated optically and electronically.
