METHOD AND APPARATUS FOR CONTROLLING THE OPTICAL OUTPUT POWER FROM A BURST MODE LASER

摘要

An optical network terminal is provided for use in a passive optical network (PaN) The optical network terminal includes a data port for receiving data packets from an external device and a processor for converting the data packets to data link frames In addition, the optical network terminal includes a memory configured to store a time division multiplexing scheme identifying a time slot assigned to each of a plurality of network nodes in the paN for transmission of upstream optical signals An optical transceiver is provided for converting the data link frames to upstream optical signals and transmitting the optical signals on an upstream TDMA (time division, multiple access) channel to an Optical Line Terminal (OLT) The optical transceiver includes a burst mode laser diode for generating th optical signals and a burst mode laser driver for biasing the laser diode with a bias signal and a modulation bias signal.
