PRODUCT INFORMATION
860nm
1A255
High-Performance LED
Baseband Video
The low thermal droop of this device
allows baseband video transmission
with minimum distortion. The dou-
ble-lens optical system provides for
optimum coupling of power into the
fiber.

PRODUCT INFORMATION
ST-2A
Package
Emitter or Detector in ST® Package
Mitel emitters and detectors can be
provided in this low-profile ST®
package. The device is electrically
isolated from the ST® receptacle to
facilitate electrical connection. And
optimum fiber-coupled power or
responsivity is ensured by active
alignment against the fiber.
