When it comes to processing data and performing control and diagnostic functions inside an airplane, there is really just one underlying objective: completely reliable transmission of the highest possible data rates via optical data transmission. This calls for sophisticated computer architectures with high-speed networks onboard, necessitating the use of high-speed electronic packages, as well as optical glass fibers in high-speed networks. This enables data transmission rates that are many times higher than those of electric cables and conventional packaging technologies.

In addition to the aviation industry’s key requirements of reducing weight and increasing safety measures, there is also the need for more data to be transferred at a faster rate. However, data can only be transferred at high speeds, if all of the components involved are designed for operation at high frequencies. This phenomenon is also evident for diagnostic systems used by pilots, as well as for the information and entertainment systems and internet services used by airline passengers. Reliability is a key issue, since airline electronics are exposed to demanding environments. Thus, hermetic packages designed for higher frequencies that house the respective optical signal transmitting and receiving units are required.
