Abstract
An apparatus-transmitting signals in a network includes a light source generating an optical signal for encoding information transmitted over a light path of the network, a modulator controlling the optical signal to generate chirped optical pulses having a first frequency spectrum such that when the pulses are transmitted from the apparatus and received at an end of the first light path the pulses have a chromatic dispersion penalty that is less than a predetermined penalty. Modulation control circuitry receives instructions from a remote controller and, in response to the instructions, controls the modulator such that the chirped optical pulses have a second frequency spectrum such that when the pulses are transmitted from the apparatus and received at an end of a second light path of the telecommunications network the pulses have a chromatic dispersion penalty that is less than a predetermined penalty.
