3 Overview
The 611T and 611R are a high-performance fiber optic transmitter and receiver for
composite video signals. The 611T transmitter converts a composite video signal
into a fiber optic signal and the 611R receiver converts the fiber optic signal back
into a composite video signal.
More specifically, the 611T, 611R feature:
55MHz (-3dB) bandwidth
Level (gain) and EQ (peaking) controls
