Tunable chromatic dispersion management of optical fibre communication link using SOA

High data rate communication demands the well compensated chromatic dispersion in the optical fibre communication. Generally dispersion compensated fibre (DCF) modules are utilized in the link with known fibre lengths. On the other hand, at ultra high data rates when a new user wants to access the network with a connecting cable of unknown length, automated dispersion compensation technique will ensure the error free communication with much greater flexibility to operate the network. An experiment was carried out to compensate the chromatic dispersion in an optical fibre network by passing the received data signal through an SOA. By controlling the SOA pump current, it was possible to automatically compensate the chromatic dispersion without changing the lengths of DC
