PRODUCT INFORMATION
SMA-2A
Emitter or Detector in SMA Package
Package
Mitel emitters and detectors can be
provided in this low-profile SMA
package. The device is electrically
isolated from the SMA receptacle to
facilitate electrical connection. And
optimum fiber-coupled power or
responsivity is ensured by active
alignment against the fiber.
