Abstract: A fiber optic network transmits data between a hub node and a plurality of local nodes connected by at least one unidirectional fiber ring. Downstream data streams are carried on wavelength-division-multiplexed optical carriers from the hub node to the local nodes. An optical carrier corresponding to a specific wavelength carries downstream data streams to a specific local node. Downstream data streams are multiplexed onto an optical carrier via orthogonal frequency division multiplexing. A parallel signal detector in each local node detects all downstream optical carriers. A signal processing module demultiplexes the data stream from the optical carrier having the specific wavelength corresponding to the local node. An upstream data stream is multiplexed via orthogonal frequency division multiplexing onto an upstream optical carrier having the same specific wavelength and transmitted from the local node to the hub node. Upstream data awaiting transmission is allocated to specific subcarriers and time slots.

Abstract: System(s), device(s), and method(s) are provided to route data in a mesh network of devices that can communicate wirelessly through a plurality of technologies. One or more of such devices receive broadcast message(s) from a destination device intended to receive the data, and generate a first radio link quality metric (RLQM) value based on the broadcast message(s). A source device originates and delivers a quantum of data with an embedded first RLQM value. A set of intermediate devices relays the quantum of data if a forwarding criterion is fulfilled; the forwarding criterion is based in part on the first RLQM value and a second RLQM value generated by an intermediate device in the set of intermediate devices based on the broadcast message(s). The intermediate device exploits an optical interface to transmit the quantum of data. The destination device broadcasts an acknowledgement signal in response to receiving intended data.
