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.

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.

(ST is a registered trademark of AT&T)
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.
