Latest Patents

One of his latest patents is for a Wide Area Multi-Service Broadband Network. This innovative national broadband network is based on fiber optic technology and is designed to cover a wide area, such as the contiguous lower United States. The network provides a high data rate interface for each subscriber and supports all the functions of current telephone, Internet, and cable TV networks, with sufficient excess capacity to support future applications. Signals from several thousand subscribers are multiplexed on a single fiber pair connected to an intelligent switching center. This design transforms telephone central offices into multiplexing centers rather than switching centers, significantly reducing the number of switching centers required nationwide. Approximately 500 switching centers are interconnected by an optical backbone, establishing physical layer connections between each pair of switching centers. The backbone is divided into optical network segments, with each segment covering approximately one-eighth of the contiguous United States. An integral number of space-wavelength channels are assigned to each connection through a network segment, allowing for many end-to-end subscriber connections. Space-wavelength channels are switched intact within the network segment, simplifying signal processing and facilitating operation at extremely high data rates.

Another significant patent by DeMartino is for a Transparent Optical Communications Switch. This communications switch connects multiple communicating nodes, allowing optical signals to flow transparently through the switch. Each node is connected to the switch by an optical cable containing input and output optical fibers, with each fiber carrying optical signals at multiple wavelengths. An optical beam is formed from the input signals of each multi-fiber cable, and the different input signals are spatially adjacent to each other. The signals within a particular beam are spatially gated to form multiple beam segments, which are then spatially shifted to different outputs. This innovative approach allows beams to flow along optically transparent paths through the switch, ensuring that the characteristics of the optical signals remain unaltered.
