Abstract:
A passive optical network, comprising:a host digital terminal having a variable rate transmitter to transmit a plurality of frames of data; a multiplexer coupled with an input of the transmitter to selectively provide frames of data to the transmitter; a retiming flip-flop device coupled between the multiplexer and the variable rate transmitter to transmit frames of data responsive to a control signal; a splitter coupled with the host digital terminal to multiplex the frames of data; and a plurality of optical network units, each optical network unit coupled with the splitter, and having a receiver circuit to receive the frames of data and adjust a data rate at which the frames of data are received at the optical network unit, based on timing information provided in the frames of data, wherein a data rate of a first optical network unit is different from a data rate of a second optical network unit.
