We introduce digital precompensation for optical nonlinearities. A 10-Gb/s transmitter
subsystem is described. Experimental results, across 320 and 1280 km of standard single …

Intensity modulation with direct detection (IM-DD) dominates the commercial short-reach
optical communications. However, when upgrading the data-rate distance product to 1000 …

We demonstrate unrepeated optical transmission of 20-Gb/s quadrature phase-shift-keying
(QPSK) signals over a 200-km-long standard single-mode fiber (SMF) without using any …

We review recent work on electronic dispersion precompensation, and present the results of
simulations investigating the compensation of chromatic dispersion and intra-channel fibre …

We present 10-Gb/s transmission with a directly modulated laser (DML) avoiding inline
dispersion compensating by electronic precompensation. To apply this technique of …

An intersymbol interference (ISI)-suppressed optical multilevel modulation technique that is
applicable to a wide range of binary and multilevel signaling is proposed. It employs binary …

This study reveals that electronic dispersion compensation (EDC) allows migration of
existing 2.5 Gbit/s metro and core networks to 10 Gbit/s without installation of DCF. This work …

We present a novel technique for dispersion compensation by exploiting the filtering
properties of a fully reconfigurable serially coupled microring resonator (MRR) structure in …

The impact of fibre nonlinearity on the performance of systems employing electronic
precompensation is discussed, and the results of simulations demonstrating the …

Digital electronic precompensation of intrachannel nonlinearities is studied in a transmission
system which consists of 100% dispersion-compensated spans. Different Mach-Zehnder …
