Abstract

A circuit board is formed with the general construction of a conventional board with glass fibers embedded in a material such as epoxy, but some of the fibers are arranged to provide channels for optical communications between components on the card or board and between cards or between boards. In one construction, some fibers emerge from the board and are terminated in a connector. An optical glass cable interconnects cards or boards. In another construction, a cloth that has been woven of glass fibers is formed as a conventional structural part of the board or card. Connections are made to the glass fibers by drilling into the board or card and into an individual fiber.
