APPLICATIONS

BrightEye 45 can be utilized in any number of different applications where con-
version of HD, SD or ASI signals to optical is required. The reclocked electrical
input can also be distributed to four electrical output BNCs.

As shown in the example below, this unit can accommodate the need to send the
input signal optically to a remote location as well as distribute the input to other
electrical destinations.The HD, SD, or ASI input can be converted and output
from the optical connector to long distances (up to 20 kilometers of single mode
fiber).

Another advantage of using optical signal distribution is the electrical isolation
provided allowing complete freedom from ground loops.

HD Optical Conversion and Electrical Distribution

One application, shown in the illustration below, utilizes fiber optic transmission
to send a converted SDI signal from a serial digital router to an SDI switcher
with an optical I/O in another building. Four additional outputs are available for
other local applications from the BNC connectors.
