BS EN 62496 is a series on optical circuit boards. Optical circuit boards is a laminated sandwich structure of conductive and insulating layers. BS EN 62496-2 specifies a method of defining the conditions for measurements of optical characteristics of optical circuit boards. The method comprises the use of code reference look-up tables to identify different critical aspects of the measurement environment. The values extracted from the tables are used to construct a measurement identification code, which, in itself, captures sufficient information about the measurement conditions, so as to ensure consistency of independently measured results within an acceptable margin. Recommended measurement conditions are specified to minimise further variation in independently measured results.
BS EN 62496-2 on optical circuit boards is useful for:
Bandwidth densities in modern data communication systems are driven by interconnecting speeds and scalable input/output (I/O) and will continue to increase over the coming years, thereby severely impacting cost, and performance in future data communication systems, bringing increased demands in terms of signal integrity and power consumption. The projected increase in capacity, processing power and bandwidth density in future information communication systems will need to be addressed by the migration of embedded optical interconnects into system enclosures. In particular, this would necessitate the deployment of optical circuit board technologies on some or all key system cards, such as the backplane, motherboard, and peripheral circuit boards.
Many varieties of optical circuit board technology exist today, which differ strongly from each other in terms of their intrinsic waveguide technology. As shown in BS EN 62496-2, these varieties include but are not limited to fibre-optic laminate, polymer waveguides and planar glass waveguides. BS EN 62496-2 provides a detailed overview of the state of the art of such optical interconnect technologies. BS EN 62496-2 specifies a method of capturing sufficient information about the measurement conditions for a given optical circuit board to ensure consistency of measurement results within an acceptable margin. Using BS EN 62496-2 you can specify a method of defining the conditions for measurements of optical characteristics of optical circuit boards.
