Abstract
A fiber optics network has a physical layer that can accommodate HFC type CATV communications or G.983.1 type communications. Downstream communications are performed using HFC to take advantage of the multiple simultaneous broadcast capability. Upstream communications are performed using G.983.1 to take advantage of the resistence to ingress noise and the more standardized approach offered by G.983.1.
Claims10
A fiber optic network system, comprising:
- a physical layer, including a provider-end transceiver connected to a user-end transceiver via a fiber optic cable;
- downstream communications from the provider-end transceiver to the user-end transceiver being carried according to a HFC protocol;
- and
- upstream communications from the user-end transceiver being carried according to a G.983.1 protocol.

A fiber optic communication method, comprising:
- carrying downstream communications from a provider-end to a user-end according to a HFC protocol;
- and
- carrying upstream communications from the user-end to the provider-end according to a G.983.1 protocol;
- wherein the downstream communications and the upstream communications are carried over the same physical layer via a fiber optic cable.
