Output Patterns for Area Sensing
This series includes models equipped
with area sensing functionality, a first for
Digital Fiber Amplifiers. This
Output Patterns for Normal Operation
Outputs 1 and 2 can be set to operate independently and either Light ON mode or
Dark ON mode can be selected (independently) for channels 1and 2 making a total
of 4 possible output patterns.

whether the incident level is inside or
outside the threshold area. The 2 output
