PRODUCT INFORMATION
840nm
1A239
High-Performance LED
Datacom, General Purpose
This device is designed for Ethernet
and general applications and offers an
excellent price/performance ratio for
cost-effective solutions. Since it oper-
ates at low drive current, it generates
minimal heat — reducing cooling
requirements in systems employing
large numbers of LEDs.

PRODUCT INFORMATION
Pigtail-3A
Package
Emitter or Detector in Pigtail 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 detec-
tors in this package.
