Different aspects of electronic distortion equalization at 40Gbit/s are highlighted: from the experimental assessment of analog equalizer circuits to the estimation of the digital processing effort
We report here a new progress of Remote Amplified Modulators for wavelength flexible and transceiver cost sensitive fix/mobile access, metro and short reach networks.
We demonstrated 40Gbit/s optical link by coupling a silicon (Si) optical modulator to a germanium (Ge) photodetector from two separate photonic chips.
A polarisation-independents, push-pull InP Mach-Zehnder modulator for 40Gbit/s all-optical regeneration has been implemented in a loop transmission scheme.
The authors present results showing that walkoff and dispersion effects are reduced when only 1 km HNL-DSF fibre is used in a nonlinear optical loop mirror (NOLM).
The authors report straight-line single-channel 40Gbit/s RZ data transmission over 240km of standard fibre with periodic dispersion compensation.
A successful, error-free 1Tbit/s (40Gbit/s x 25ch) WDM transmission experiment over 342km of nonzero dispersion (TrueWave) fibre is described in which a 40Gbit/s optical time-division-multiplexing
Mode-division multiplexing is demonstrated over five modes for the first time.
Five 100G PDM-QPSK data streams have been multiplexed, transported over 40km, demultiplexed and detected.
We demonstrate the longest WDM transmission at 200Gb/s using single-carrier PDMQPSK modulation format.
