Abstract :
A 160 Gbit/s (=10 Gbit/s times 16) optical time-division multiplexing (OTDM) signal is successfully transmitted over a 26 km-long photonic crystal fibre (PCF). The transmission induced signal pulse broadening is suppressed to only 0.2 ps (from 2.1 to 2.3 ps) because the fabricated PCF has low polarisation-mode dispersion (PMD) of 0.1 ps/km1/2, and the total chromatic dispersion of the transmission line is suppressed to 0.015 ps/nm by using a dispersion-compensation fibre. The transmitted signal is demultiplexed using four-wave mixing in a 100 m- long dispersion shifted fibre, where a phase modulation-based 10 GHz pump pulse source is newly adopted.
