Raytheon Control-By-Light Fiber Optic
Transceiver Receives LONMARKR Approval for Intelligent Building
Control Networks.
Raytheon's Transceiver is First to Implement EIA Fiber Optic Standard
SUDBURY, Mass., September 30, 1999 -- Raytheon
Control-By-LightTM, a leader in distributed sensing and fiber optic technology
applications, announced today that its fiber optic modular transceiver has
received LONMARKR
approval for use in open multi-vendor LONWORKSR 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, 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 NeuronR microprocessors
in LonWorks nodes to fiber optic backbones, links or networks. The transceiver
also is used within Raytheon's popular LonWorks-based twisted pair to fiber
router.
"We are excited that our fiber optic transceiver has received
formal approval from the LonMark Interoperability 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 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 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 over a single fiber
optic cable, 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 or 50/125 micron multimode fiber.
LonWorks control
networking technology, developed by Echelon Corporation, 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 LonWorld99Ô, 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.
