Electronic Dispersion Pre-Compensation in PM-QPSK Systems over Mixed-Fiber Links

Abstract

Dispersion pre-compensation is shown to potentially lead to a substantial non-linearity reduction in PM-QPSK links that use a mixture of high and low dispersion fibers. However, the much larger PAPR of the pre-compensated signal poses challenging requirements on the transmitter.
