3 The product
Black Box LWU
The
Black Box LWU
series products from
Black Box
set a new standard for Free
Space Optical transmission systems. They provide simple and easy to installation
solution that is unique in la ser based networking. This new range of products
incorporates a lightweight, compact mechanical design with a factory-set optical
system, which allows end-users to benefit from simple and quick installation. The
Black Box LWU
is more competitively priced th an 2.4 GHz radio solutions and the
bandwidth provided can be about ten times higher.
Black Box LWU
range offers cost effective, reliable and secure laser based free
space optical transmission for local area networks (LAN) at full duplex Fast Ethernet
wire s peed. The transmission carries data using a concentrated laser beam and a
unique modulation technique is employed to ensure error free data transfer over
distances of up to 200 meter. Transparent and wire speed data transfer together with
virtually zero latency ensures that the
Black Box LWU
system can be easily
integrated into any environment. The
Black Box LWU
series use laser light as a
transmission medium. As with all
Black Box LWU
systems this means that frequency
licenses are not required and transmission is not affected by electro -magnetic
interference. The data transmission via a laser beam is secure as it is extremely hard
to intercept, and cannot be detected by spectrum analysers. In the case of a
Black
Box LWU
system the laser link is considered a “virtual” fibre in the air.
The
Black Box LWU
system comprises of two Laser Heads, two Outdoor
Interconnection Units (OIU) and two sets of interconnection cables — one at each
end. The Laser Heads are installed outdoors, usually on rooftops or sidewalls of
bu ildings, where a clear optical path exists between the two sites. Next to the head
the Outdoor Interconnection Unit provides fast and easy interconnection between the
laser head and the cable coming from the network equipment. Moreover the OIU
houses the Power Supply Unit (PSU) of the system and the network interface. The
PSU provides the low voltage power required to operate the laser. Each
Black Box
LWU
head contains built-in transmission monitoring service, which features a visual
signal strength indicato r and LINK status information accessible on the rear side of
the head assembly through a window. In addition
Black Box LWU
units are
equipped with optical aid to target the remote head easily. All that makes the
installation real fast and easy even for people who have never dealt with FSO
equipment before
By utilizing IEEE, and ITU standard compliant interfaces
Black Box LWU
system
protects the customers’ investments in long-term projects. Provides fast and easy
connection for Fast-Ethernet, or PDH computer or telephone networks.
