Abstract:
1. A wavelength division multiplexing passive optical network (WDM-PON) for performing bi-directional communication, the WDM-PON comprising: a first interface at an access point to input a first set of signals configured to comply with a first transmission platform and output a second set of signals based on the first set of signals, wherein each of the second set of signals has a different wavelength, which is mapped to a corresponding one of the first set of signals, wherein the second set of signals are configured to comply with a WDM-PON data transmission platform while having a data transmission sequence in compliance with the first transmission platform and to propagate according to the WDM-PON transmission platform through a transmission medium; and one or more first remote distribution nodes coupled to the access point, wherein the transmission medium carries the second set of signals traveling along optical channels in a first direction.
