PRODUCT INFORMATION

1A302

FM Video

1320nm

High-Performance LED

The low harmonic distortion makes

this device ideal for subcarrier FM

video applications. Video transmis-

sion can be accomplished with mini-

mum distortion. The double-lens opti-

cal system provides for optimum cou-

pling of power into the fiber.
