Model 722A

Description
The HR-722A Fiber Optic Communication System allows
direct connection of VGA computers for signal transmission
over Fiber Optic cable spanning distances to 2500 ft (0.75
kilometers) on
multi-mode
or 35 kilometers on
single-
mode
fiber (approximate based on loss budget). The HR-
722A features excellent picture quality with bright and sharp
images. Gone are the usual signal degradation and smearing
of coax or twisted pair video transmission at extended
lengths. Signal integrity is also maintained through fiber
optic cables' immunity to electrical interference and cross
talk. The lightweight and small diameter fiber reduces
installation time, particularly since only 1 fiber is needed.
Fiber optic cable also has certain intrinsic benefits for
installation success including resistance to electromagnetic
interference (EMI), lightning, and the elimination of ground
loops through electrical isolation.
The HR-722A Series includes the HR-722A-T Transmitter
and HR-722A-R Receiver, both with a 15 pin HD female
connector and 3.5 mm Stereo Audio jack. Power supplies
are also included in the package for the transmitter and the
receiver.
The system is generally used with standard Multimode Fiber
(62.5/125 um or 50/125 um) with common ST- connector
type. System integration allows all other Hall Research
Technologies, Inc. VGA compatible products to be used in
conjunction with the Fiber Optic system including
Distribution Amplifiers, Switches, and VGA Breakout Cables.
