Raytheon Control-By-Light Fiber Optic Transceiver Receives LONMARK Approval for Intelligent Building Control Networks.SUDBURY, Mass.--(BUSINESS WIRE)--Sept. 30, 1999-- Raytheon's Transceiver is First to Implement EIA (Electronic Industries Alliance, Arlington, VA, www.eia.org) A membership organization founded in 1924 as the Radio Manufacturing Association. It sets standards for consumer products and electronic components. Fiber Optic Standard Raytheon Control-By-Light(TM), a leader in distributed sensing and fiber optic technology applications, announced today that its fiber optic modular transceiver has received LONMARK(R) approval for use in open multi-vendor LONWORKS(R) control networks. The device implements the newly approved Electronic Industry Association fiber optic transceiver protocol standard (EIA-709.4). Achieving the EIA standard and LonMark approval further positions Raytheon Control-By-Light as a leading supplier of fiber networked control solutions for building automation, industrial, and security and access control applications. The EIA standard, co-authored by Raytheon Control-By-Light, supports a new generation of interoperable The ability for one system to communicate or work with another. See interoperability. , energy-efficient, intelligent buildings by enabling lights, appliances, heating/air-conditioning equipment, security and access control, power control, sprinkler systems, audio/video equipment and other separately manufactured products and systems to be networked via fiber optic transceivers that communicate using the standard LonWorks protocol. Raytheon's standard modular transceiver provides the interface that links Neuron neuron, specialized cell in animals that, as a unit of the nervous system, carries information by receiving and transmitting electrical impulses. neuron or nerve cell Any of the cells of the nervous system. (R) microprocessors in LonWorks nodes to fiber optic backbones, links or networks. The transceiver also is used within Raytheon's popular LonWorks-based twisted pair A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable (Alexander Graham Bell invented this and was awarded a patent for it in 1881). to fiber router router Portable electric power tool used in carpentry and furniture making that consists of an electric motor, a base, two handle knobs, and bits (cutting tools). A router can cut fancy edges for shelving, grooves for storm windows and weather stripping, circles and ovals . "We are excited that our fiber optic transceiver has received formal approval from the LonMark Interoperability The capability of two or more hardware devices or two or more software routines to work harmoniously together. For example, in an Ethernet network, display adapters, hubs, switches and routers from different vendors must conform to the Ethernet standard and interoperate with each other. Association," said Brian D. Morrison, director of Raytheon Control-By-Light. "Today's announcement will allow engineers, systems integrators and building operators -to improve their systems by using fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber as the backbone of a building's network. -Fiber has the highest bandwidth of any medium and can transmit information faster over longer distances, without costly repeaters, to maintain signal strength. The advantage of an open interoperable control system using fiber LonWorks interconnects is the ability to create a single cohesive cohesive, n the capability to cohere or stick together to form a mass. control system that is more reliable, less expensive and easier to install than systems that rely on proprietary vendors and copper-based networking solutions." Because fiber is tamper-resistant and intrinsically immune to electromagnetic disturbances, lightning, chemicals or other interference, it is ideal for large, complex building projects with substantial message traffic. Raytheon Control-By-Light's EIA 709.4 bi-directional fiber products allow two-way communication Two-way communication is a form of transmission in which both parties involved transmit information. Common forms of two-way communication are:
fibre optic cable transmission line, cable, line - a conductor for transmitting electrical or optical signals or electric power , which can cut the cost of a fiber-based LonWorks building automation network in half, with all the reliability of fiber and full LonWorks connectivity. In addition, Raytheon Lonworks-based fiber solutions are as easy to install as twisted pair and can easily be mixed and matched with non-fiber channels and subnets using Raytheon's ultra-reliable bridges, routers and transceivers. Raytheon's LonMark approved transceiver allows users to implement multiple subnets with more than 750 fiber optic nodes. Designed to LonWorks and EIA 709.4 standards, the transceiver includes an Echelon 3120 Neuron chip for built-in test to monitor the fiber optic network, and can be used with 62.5/125 microns, 100/140 micron micron: see micrometer. One micrometer, which is one millionth of a meter or approximately 1/25,000 of an inch. The tiny elements that make up a transistor on a chip are measured in micrometers and nanometers. See process technology. or 50/125 micron multimode fiber An optical fiber with a larger core than singlemode fiber. It is the most commonly used fiber for short distances such as LANs. Light can enter the core at different angles, making it easier to connect the light source to broader light sources such as LEDs. . LonWorks control networking technology, developed by Echelon Corporation Echelon Corporation (NASDAQ: ELON) designs control networks to connect machines and other electronic devices, for the purposes of sensing, monitoring and control. , is the leading open, networked control solution for building and home automation, industrial transportation and public utility applications. Just as the PC led to an explosion in the use of computer technology by lowering costs and providing flexibility, using open, interoperable control technology lowers the installed cost of control systems, improves efficiencies and saves costs through the system life cycles. Since it was formed in 1994, the LonMark Interoperability Association has been a driving force in the establishment of interoperable standards for building, industrial and residential/utility automation. As a sponsor of the LonMark Interoperability Association, Raytheon has joined with other leading manufacturers using LonWorks devices to promote the benefits of open interoperable multivendor control networks. In addition, Raytheon is a Platinum Sponsor of LonWorld99(TM), the largest gathering of LonWorks users, developers, integrators, consultants, and equipment specifiers from the around the world, to be held in Amsterdam, October 13-15, 1999. Raytheon Control-By-Light delivers today's most technologically advanced, reliable and affordable fiber optic sensing and control solutions for commercial building and industrial automation applications. Raytheon's fiber optic solutions are developed and marketed by the Commercial Electronics Division of global technology leader Raytheon Company.
