Abstract: Three alternate fiber ribbon interconnections are described for optically interfacing two 4-channel optoelectronic transceiver modules, each module having separate, spaced apart transmitter and receiver diode arrays. In each instance the optical interconnection is made by either an 8 fiber or a 12 fiber ribbon and associated fiber end connectors.

Abstract: Optoelectronic transceiver modules having photoemitter and photodetector arrays spaced from each other are interfaced to a single optical fiber ribbon having evenly spaced optical fibers.

Abstract: An optical head comprises an optical head body having a proximal face and a distal face. Eight optical fibers extend through the optical head body. Each of the optical fibers has fiber ends on the proximal face and the distal face. The fiber ends on the proximal face are grouped in two fiber end arrays each comprising four fiber ends evenly spaced from each other. Each of the fiber end arrays is in optical alignment with a transmitter chip or a receiver chip. The fiber ends on the distal face are evenly spaced from each other in a single array of eight fiber ends.
