Abstract:
1. An optical network unit, comprising: a first optical network interface in communication with a first user device configured to operate in a non-optical domain and an optical network and configured to: a second optical network interface in communication with a second user device configured to operate in said non-optical domain and said optical network and configured to receive optically-encoded Radio Frequency (RF)-band downstream signals from said optical network for transmission to said second user device; a third optical network interface in communication with and configured to receive collision related signals from said optical network, said collision related signals enabling bi-directional optical networking on said third optical network interface; and an access device comprising a digital processor configured to implement a carrier sense multiple access/collision detection (CSMA/CD) protocol with respect to said downstream and upstream data signals, said RF-band downstream signals, and said collision related signals.
