Pigtail-3A
Emitter or Detector in Pigtail Package
Package
Mitel emitters and detectors can be
provided in this pigtail package with
a wide selection of fiber types. The
device is electrically isolated from
the pigtail receptacle to facilitate
electrical connection. And optimum
fiber-coupled power or responsivity
is ensured by active alignment
against the fiber. A special design
maximizes the return loss for detectors in this package.
