GByte-class skewless parallel-optical-data-link subsystem

This paper describes 48 x 100 Mbit/s data link subsystem using a 6 x 1.1 Gbit/s arrayed optical transceiver module and 15-ns deskew function ICs. This link will be applied to the real world computing (RWC)-1, which is one of the massively parallel computer with 1,000-class processor elements.
