ABSTRACT:
In accordance with the teachings of the present invention, a system and method for managing different transmission architectures in a passive optical network (PON) is provided. In a particular embodiment, a method for managing different transmission architectures in a PON includes transmitting traffic in an upstream or downstream direction in a first time-slot in a PON at each channel of a first set of one or more channels. The method also includes transmitting traffic in the same upstream or downstream direction in a second time-slot in the PON at each channel of a second set of one or more channels that provide greater bandwidth than the first set of one or more channels, wherein at least one channel of the first set at least partially overlaps at least one channel of the second set but is not identical to the at least one channel of the second set.
