Abstract
A link extender configured to extend a range of an optical transceiver module is provided. The link extender includes an array of semiconductor optical amplifiers (SOAs) configured to amplify an optical signal received from the optical transceiver module, a first plurality of variable optical attenuators (VOAs) configured to control a power output of the amplified optical signal output from the array of SOAs, and a plurality of dispersion compensation and filtering (DC&F) devices configured to compensate for chromatic dispersion of the optical signal.
