Optical fiber communications offer larger data processing capacity than any other technology; with the added benefit of small weight and low power consumption. Optical communication is a proven technology that has been deployed in harsh defense and avionics applications for a great number of years.
In space and avionics applications, failure is not an option. Components must stand extreme heat, cold, radiation, shock, and vibration, yet deliver reliable performance. In this article, we examine the reliability requirements of such devices and the steps involved in designing a test program to ensure reliability and performance.
