1A302 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – High-Performance LED FM Video

PRODUCT INFORMATION
1320nm ^1A302
FM Video
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.
