1A314 Datasheet, PDF (1/2 Pages) Mitel Networks Corporation – High-Performance LED

PRODUCT INFORMATION
860nm
1A314
High-Performance LED
Baseband Video
The exceptionally low thermal droop
of this device allows baseband video
transmission with ultimate quality
and minimum distortion. The double-
lens optical system provides for opti-
mum coupling of power into the fiber.
