Abstract:
An apparatus includes a TDM PON optical transceiver including a direct-detection optical receiver. The direct-detection optical receiver is configured to demodulate data from a temporal segment of a data modulated optical signal, wherein the optical carrier frequency of the segment varies at a rate of, at least, 1 giga-Hertz per second.
