A controller board for a 64 x 64 port optical switch is a core component in the OSMOSIS (Optical Shared Memory Supercomputer Interconnect System), which uses optical switch elements to transfer packet data throughout the system. The switch can transmit 2.5 Tbit of data in 1 sec and can achieve line rates of 40 Gb/sec.
The board consists of 36 layers, 36,053 blind vias, 29,246 connections, a total trace length of 1.6 mi, and requires multiple passes through the plating and drilling processes. It accomodates 40 back-to-back, two-sided compliant pin connections.
