Qualification and Reliability
To help ensure high product reliability and customer satisfaction, Agere Systems is committed to an intensive qual-
ity program that starts in the design phase and proceeds through the manufacturing process. Optoelectronics mod-
ules are qualified to Agere Systems internal standards using MIL-STD-883 test methods and procedures and using
sampling techniques consistent with Bellcore requirements. The 1241/1243/1245 series of transmitters have
undergone an extensive and rigorous set of qualification tests. This qualification program fully meets the intent of
Bellcore reliability practices TR-NWT-000468 and TA-NWT-000983. In addition, the design, development, and man-
ufacturing facility of the Optoelectronics unit at Agere Systems has been certified to be in full compliance with the
latest ISO-9001 Quality System Standards.
