Abstract
Wavelength division multiplexing (“WDM”) passive optical networks (“PON”) to transport signals having various access platforms are described. For one embodiment, a WDM PON performs bi-directional communications, and includes an interface. The interface transfers one or more signals having a first platform to a WDM-PON data transmission platform at an access point of a network to propagate through a single transmission medium, to one or more remote distribution nodes in between a Central Office and an optical network unit. The single transmission medium carries three or more optical channels traveling in both directions.
