ABSTRACT:
A control module is configured to receive one or more input signals. An optical selection network includes a plurality of optical input ports configured to receive respective optical waves at an operative wavelength, and at least one optical output port configured to provide an optical wave at the optical wavelength. The optical selection network is configured to receive one or more control signals from the control module, and in response to the control signals, provide a high transmission path for the operative wavelength from an optical input port, determined by the input signals, to the optical output port at a predetermined time with respect to a time reference in at least one of the input signals, and provide a low transmission path for the operative wavelength from each of a plurality of optical input ports, determined by the input signals, to the optical output port at the predetermined time.
