NIC No Internal Connection July 2001 - 5/8 Qualification and Reliability In order to secure all his customers, Alcatel Optronics launch a complete qualification program. This qualification is based on manufacturer's qualification in agreement with Telcordia GR-253-Core specification (Generic Reliability Assurance Requirements for Optoelectronic Devices Used In Telecommunications Equipment), MIL STD 883D, ITU-T G652, G.957, G.783, G-691 G-691, IEC68-2 IEC68-2 and Telcordia TR-EOP-000063 TR-EOP-000063 either for external manufacturers or Alcatel Optronics. The qualification program is divided in two steps : In order to quickly qualify the main interfaces, a pre-qualification phase evaluates the level of robustness of SDH components and estimates the potential mechanical stress due to the mounting process of the different parts in the package. A qualification phase with complete functional tests before and after each reliability tests evaluates the reliability data on whole module.
