Abstract: A cable swivel is provided for maintaining optical fiber bend limits at entry portals of a optic fiber shelf for the shelf's entire range of motion, from being fully closed to being fully open. Bend limits are maintained as optical fiber is directed on paths through a shelf entry portal between the shelf interior and wire brackets on the shelf exterior. Fibers are retained, organized and strain relieved by the cable swivel such that directed fiber is maintain at a minimum bend radius on such fiber paths. The curved surface of the cable swivel allows the shelf to be accessed without excessive bending of so routed optical fibers. In this manner, optical signal degradation and/or total loss is avoided by limiting the bending of routed optical fiber to radii in excess of a predetermined minimum bend radius.

Abstract: A plurality of optical fibers (14-14E) are interconnected by using connectors each comprising an optoelectronic device (13-13E) adapted to be connected to an end of each optical fiber for converting optical signals to electrical signals and for converting electrical signals to optical signals. Each connector has a first contact (12-12E) having a cylindrical plug end and a cylindrical socket end located on a common axis and a transverse conductor (21) extending transversely to the axis (20) from the first contact and connected to the optoelectronic device of the connector. The plug end of each contact is adapted to fit snugly within the socket end of another first contact, whereby all of the contacts may be connected and arranged along the common axis. Each of the contacts is free to rotate with respect to other contacts to which it is connected; this permits the various optical fibers to extend in different radial directions from the axis.

Abstract: Disclosed is an apparatus for the optical interconnection of circuit packs and components mounted on circuit packs, and a method of manufacture. Optical fibers are bonded to a flexible substrate. The substrate includes tabs that can be terminated by standard V-groove silicon chip connectors for optical connection to the edges of circuit packs.

Abstract: Described is a method for assembling multi-fiber array connectors. V-grooved silicon chips are placed in a holder which allows the chips to "float" with respect to each other and adjust to varying fiber diameters. Once the fibers are inserted, the chips are clamped and cemented together with the fibers fixed in the grooves.

Abstract: Connector apparatus for interconnecting optical fiber cables. The apparatus comprises a pair of plug members each holding a truncated pyramid configured member universally mounting a substrate device terminating light carrying fibers of optical fiber cables. A sleeve member is arranged to slidably receive each substrate device inserted in one end thereof and apply quadrantal forces to both substrate devices to align and optically couple together corresponding ones of the fibers terminated on each substrate device.

Abstract: A copier document apparatus (10) for feeding original document sheets (21) to and from a registration position at an imaging station (20) of a copier with a reversible direction of motion document feeding belt (14) having one flight (18) of the belt overlying the imaging station for document feeding and a second flight (22) spaced therefrom, and apparatus (32) for applying pressure to an area of the back of the first belt flight (18), which pressure is substantially changed in one direction of motion of the belt relative to the other direction of belt motion, to provide decreased pressure between the belt and the document for registration (23) but increased pressure for positive document ejection, in which this pressure change is self actuating and solely from the reversal movement of the belt by a frictional actuating system (30) which is engaged and moved without slippage by the second (upper) belt flight (22) through a connecting lever system (24) connecting the frictional actuating system (30) with the pr
