A system and method for filling voids between optical signals during switching in an optical telecommunications system. The optical switch includes a void filling and scheduling software program resident in memory and executable by a processor. The memory also includes the wavelength, position in time, duration for each void between previously scheduled optical data packets. As a new optical data packet arrives at the optical switch, the void filling and scheduling software program will calculate the available delay for each delay line as measured from the arrival time of the new optical signal and schedule the new optical signal within a particular void if (1) one of the available delays falls within the position in time of one of the voids and (2) if the duration of the new optical signal measured from the particular available delay fits within the duration of that void. If the new optical data packet will not fit within any of the existing voids, the void filling and scheduling software program will use a conventional scheduling routing to schedule the new optical data packet on an output fiber.
