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.
