High reliability of custom products is implemented at all design and production stages in an ISO-9001 environment. Reliability analysis is supported by field experience and Relex software, allowing use of predictive models, such as 217Plus, PRISM, Telcordia, and FIDES, as well as failure mode analysis. Card level options include conductive cooling, board stiffeners for improved vibration tolerance, hot swap capability, and signal redundancy. At the system level, our custom designs include redundant optical transceivers, auxiliary power supplies, and robust transmission protocols that reduce the probability of accepting corrupted data (residual errors) to extremely low levels. The various options are applied as appropriate for the given cost, reliability, and environmental requirements of the system over the intended product life cycle.
Several processes are used to further support high reliability designs. Besides the acceptance testing at rated temperatures used for all electronic products, high-reliability products receive additional environmental stress screening and qualification testing to further validate product reliability and life. Detailed analyses are conducted, including the calculation of product reliability and life, supported by manufacturer’s data, empirical data, and component traceability. Additional testing includes shock, sinusoidal vibration, random vibration, humidity, acceleration, low pressure (altitude), and high pressure (in oil). Our engineering department will work closely with you to develop test plans for design, production, and qualification that make sense for your application.
Multiplexer products include advanced diagnostics and health monitoring functions to ensure systems are operating properly and to provide early warnings of any negative trends, for example degradation of cabling. Critical performance parameters, such as optical power, rail voltages, temperature, and fault conditions, are available through serial channels or Ethernet protocols. Customer equipment may access the diagnostics directly through open protocols, e.g. Modbus, or via Graphical User Interface (GUI) software. Built-in test features, such as bit error rate tests and video test patterns, simplify system-level troubleshooting by helping to isolate any connection problems.
We provide rapid solutions for multiplexing and data conversion applications in the harshest environments, designed to your specifications. The results are proven, rugged products.
