All dimensions in mm
The very high speed and low capaci-
tance of this InGaAs PIN Photodiode
makes it ideal for datacom, telecom
and general purpose applications. Its
double-lens optical system is
designed for single-mode fiber as
well as for multimode fiber with core
diameter up to 62.5m. And when
used in the Pigtail-3A package, the
optical return loss is very high.

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.
