Abstract

Ultra-high speed optical time-division-multiplexed (TDM) transmission is one of the key technologies to realize future Tbit/s optical networks. We reported 100 Gbit/s [1] and 200 Gbit/s optical TDM transmission [2] using high-speed optical techniques such as short pulse generation by mode-locked fiber ring laser (ML-FRL), supercontinuum (SC), time-division multiplexing by the planar lightwave circuits (PLC), prescaled PLL timing extraction using four-wave mixing (FWM) in a laser-diode-amplifier (LDA), and alloptical demultiplexing using FWM. In order to increase the signal bit rate, the influence of the dispersion slope (^3) of the transmission fiber must be overcome. In this report we demonstrate successful 400 Gbit/s optical TDM transmission experiments with 0.98 ps signal pulses through 40 km of dispersion-slope compensated transmission fiber. We upgraded the PLL timing extraction and all-optical demultiplexing for 400 Gbit/s operation.
