Abstract: A controller area network (CAN) comprising a plurality of CAN nodes that communicate via a CAN bus that comprises a fiber optical network. The fiber optical network uses a single fiber and a single wavelength for transmit and receive, and comprises a passive reflective optical star. The reflective optical star comprises an optical mixing rod having a mirror at one end. The other end of the reflective optical star is optically coupled to the transmitters and receivers of a plurality of optical-electrical media converters by way of respective high-isolation optical Y-couplers. Each CAN node produces electrical signals (in accordance with the CAN message-based protocol) which are converted into optical pulses that are broadcast to the fiber optical network. Those optical pulses are then reflected back to all CAN nodes by the reflective optical star.

Abstract: An apparatus configured to function as a pluggable active optical connector that is modular with one or more channels and that converts electrical signals to optical signals and vice versa. On one side, the apparatus has a pluggable electrical interface to a line replaceable unit (LRU); on the other side the apparatus has a pluggable optical interface side to an aircraft fiber optic wiring bundle. The apparatus is pluggable to different types of LRUs including rack-mounted and bolted-down LRUs. The apparatus includes electronic and photonic components sufficient to enable electrical/optical conversion totally within a standard-sized aircraft connector. The apparatus is adaptable to various data communication protocols and has the flexibility to be used in either a single-fiber or a dual-fiber bidirectional data link.

Abstract: Systems and methods that use a passive differential optical sensor to measure the level of liquid in a reservoir (e.g., a fuel tank or other storage container). More specifically, the passive differential optical liquid level sensor solves the problem of common-mode intensity variations by employing three optical fibers that will be disposed vertically in the reservoir. The system comprises a side-emitting optical fiber having one end optically coupled to an optical source, a side-receiving optical fiber optically coupled to a first optical detector, and a total internal reflection optical fiber having one end optically coupled to the other end of the side-emitting optical fiber and another end optically coupled to a second optical detector. A computer or processor is configured to perform differential processing of the detected light and then determine the liquid level based on the differential processing results.

Abstract: A bidirectional, multi-wavelength fiber optical network that enables communication between electrical components (such as line replaceable units) at high data transmission rates. The proposed fiber optical network in accordance with some embodiments comprises a single plastic or glass optical fiber capable of transmitting data at rates faster than 1 Gbits/sec. In accordance with some embodiments, the number of fiber cables between line replaceable units onboard an airplane can be reduced by a factor of eight or more by substituting one gigabit plastic or gigabit glass optical fiber for four or more plastic or glass optical fibers.

Abstract: Provided are mechanisms for improving bandwidth for non-essential data on deterministic aircraft data networks (ADNs) such as ARINC 664 networks. A switch such as an ARINC 664 switch maintains rate constrains on one or more priority levels of traffic while releasing rate constraints on low priority traffic. Low priority traffic can be received at an ARINC 664 switch at rates allowed by an Ethernet physical layer. However, low priority, non-rate constrained traffic is transmitted only when there are no other scheduled messages to send. Low priority traffic can consume all available bandwidth whenever there is slack time. A switch can further be separated into zones including a standard rate constrained zone as well as a rate unconstrained zone. Internal or external cross-links can be provided between the zones for any data that needs to be transferred between zones.
