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
optical system provides for optimum
coupling of power into the fiber.

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.

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.

Note 2: Add Rthjc for emitter or detector to estimate the total thermal resistance.
Note 1: Temperature range can be extended to -55 to +125C on request.
