1A277A
High-Performance LED
FM and Baseband Video
The low harmonic distortion and low
thermal droop makes this device ideal
for subcarrier FM and baseband video
applications. Video transmission can
be accomplished with minimum dis-
tortion. The double-lens optical sys-
tem provides for optimum coupling of
power into the fiber.
