The invention relates generally to data communications using multiple data networks to transport data to one or more end user devices.

Device, system, and method for transporting data using combined broadband and legacy network infrastructures

The present invention relates to a data distribution device comprising of a core electronics suite having at least two data ports where each port is in communication with its own network transport medium. At least two broadband transceivers, each in communication with its own broadband data port, enable sending and receiving of broadband data signals. At least two converters, each in communication with its own transceiver, enable the conversion of RF modulated data signals into data packets and the conversion of data packets into RF modulated data signals. The device includes a data switch, in communications with at least two converters and at least two broadband transceivers, for inspecting and routing data packets between data ports; a processor in communication with the data switch that controls the sending and receiving of data packets between at least two converters; and an exterior housing that is sealed and environmentally hardened to allow the data switch, the processor, and the converters with their transceivers, to operate in an outdoor environment.

Outdoor hardened exo-modular and multi-phy switch

A semiconductor-based, photo detector device capable of simultaneously detecting two or more selected wavelengths of light on a pixel-registered basis. The device has detector layers of selected semiconductor materials of one micron or less in thickness interspersed with contact layers, each detector layer having a different light absorption to wavelength response curve. All contact layers, including detector bias voltages, have electrical contacts on the backside of the pixel for discrete pixel connection to mating connections on a suitable ROIC substrate. Among its several embodiments, there is a multi-color detector array and a single channel per pixel differential optical signal detector.
