Abstract :
In this contribution we compare experimental results based on application of different all-optical chromatic dispersion (CD) compensation techniques including tuneable ones. As fixed CD compensators, we used both channelized and broadband fibre Bragg gratings (FBG). Results obtained by application of thermally tuneable channelized FBGs and Gires-Tournois etalons (GTE) are also compared. In our experimental setup eight 10 Gigabit Ethernet (10 GE) channels were transmitted over 225 km of standard single mode fibre (SSMF) with no inline amplification. Signals were combined in multiplexer, amplified in a standard C-band erbium-doped fibre amplifier (EDFA) and launched in the SSMF fibre. At the receiver side, signals were first amplified in a low noise EDFA, CD was compensated by one of the elements and de-multiplexed. Partial CD pre- compensation was also tested.
