Scope

This part of IEC 62496 defines the standard interface dimensions for a terminated waveguide optical circuit board (OCB) assembly (referred to simply as assembly) using single-row thirty-two-channel connectors for polymer waveguides connected with a PMT connector, and the PMT connector is intermateable with MPO 16 specified in IEC 61754-7-4.

Purpose

With the rapid development of the communications industry, system capacity increasingly grows, resulting in a dramatic increase of the number of links between the backplane and daughter cards. Therefore, the link numbers of the next generation cards are more than the current cards. One of the best ways to cut cost is to make the current cards work well in the next generation system, which means the connector of the next generation backplane should be intermateable with the connector of current cards.

This part of IEC 62496 defines the standard interface dimensions for a terminated waveguide optical circuit board assembly using single-row thirty-two-channel connectors for polymer waveguides connected with a PMT connector, and the PMT connector is intermateable with MPO 16 specified in IEC 61754-7-4. The interconnection of backplane is one of the potential applications of this PMT connector. The small pitch waveguides will enable new applications.
