Stretched fibre based dispersion compensating module for ultra high-speed telecommunication systems

In this work, the potential efficiency of a low-loss, tunable second- and third-order dispersion compensating module based on a stretched optical fibre for ultra high-speed telecommunication systems is analysed. Experimental results at a repetition rate of 640 GHz show that precise dispersion compensation could be achieved in the range of ±0.038 ps/nm by means of an 11.3 cm maximum stretching of a 48 m long dispersion compensating fibre.
