Abstract:
1. An apparatus for transmitting signals in a telecommunications network, the apparatus comprising: a light source configured for generating an optical signal for encoding information transmitted from the apparatus over one or more light paths of the telecommunications network; a modulator operably coupled to the light source and configured for controlling the optical signal to generate chirped optical pulses of the optical signal, the chirped optical pulses having a first frequency spectrum and a first temporal pulse envelope, both the first frequency spectrum and the first temporal pulse envelope are controlled by the modulator, 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 for the first light path; and modulation control circuitry configured for receiving instructions from a remote controller and, in response to the instructions, controlling the modulator such that the chirped optical pulses have a second frequency spectrum and a second temporal pulse envelope, both the second frequency spectrum and the second temporal pulse envelope are controlled by the modulator, 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 for the second light path.
