PRODUCT INFORMATION
1320nm
1A439
High-Performance LED
Datacom
This device is designed for FDDI and
ATM 155 Mbps applications and
offers an excellent price/performance
ratio for cost-effective solutions. Its
double-lens optical system results in
optimum coupling of power into the
fiber.

PRODUCT INFORMATION
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.
