In accordance with certain embodiments, an optical network terminal (ONT) is provided that comprises a processor module, a serializer module and an optical transmitter. The processor module may represent an FPGA device, while the serializer may represent a SERDES, with the FPGA device and SERDES being formed as distinct and separate components. The processor module is configured to generate data bursts that are associated with time slots in a time division multiplexing transmission scheme. The processor module outputs the data bursts over parallel channels to the serializer module that, in turn, serializes the data bursts and outputs serial data bursts over a serial channel. The serializer module has a latency representing an amount of time for each of the data bursts to propagate through the serializer module from the parallel channels to the serial channel. The optical transmitter is joined to the serial channel and converts the serial data bursts to optical data bursts. The processor module determines a latency of the serializer module and controls the optical transmitter based on the latency of the serializer module. Optionally, the processor module may provide a burst enable signal that turns on and off the optical transmitter in order to align the optical data bursts with the corresponding time slots in the time division multiplexing transmission scheme.
