This device operates at very low drive
current, which makes it well suited for
battery-operated equipment. In fact, it
can be driven directly by TTL circuitry.

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.

All Dimensions in mm
*
The fiber-coupled power/responsivity is guaranteed to meet the LED/PIN data sheet - provided a ferrule meeting this specification is used.
