PRODUCT OVERVIEW

The BrightEye™ 45 is an electrical to optical converter and distribution amplifier
that can be used with high definition, standard definition, or ASI type inputs. The
video input is reclocked and presented on four electrical BNCs. The input is also
routed to laser diode circuitry where it is converted to an optical signal and
presented on an optical SC connector. This optical output can drive single mode
fiber to a distance of 20 kilometers. With an optical launch power attenuator,
multi-mode fiber can also be used for longer cable runs. Refer to the functional
block diagram below.

This is a simple device with no USB port and no interface to the BrightEye PC
application. It is powered by a modular style power supply. Front panel indicators
show the presence of an input signal and power. No adjustments are required on
the unit.

A glossary of commonly used video terms is provided at the end of this guide.
