Gradient index (GRIN) lens chips and associated small form factor optical arrays for optical connections, and related fiber optic connectors are disclosed. By aligning GRIN lenses within a GRIN lens chip, a more precise and reliable alignment may be achieved with respect to optical fibers than if a single conventional ferrule is utilized to align and secure both GRIN lenses and optical fibers. The GRIN lens chip may include a GRIN lens received and thereby aligned within a groove disposed between a fiber end and a terminal end of a GRIN lens holder body. The optical fibers may also be received and thereby aligned within a groove of a ferrule body. In this manner, when the GRIN lens chip containing the GRIN lenses is aligned with a ferrule body containing the optical fibers, then the GRIN lenses may be precisely located relative to the optical fibers.

Roller pairs and draw apparatus for processing glass ribbons are disclosed. The roller pairs applying force to a glass ribbon moving through the draw apparatus. The roller pairs include a first roller assembly and a second roller assembly positioned along opposite sides of the glass ribbon. A shaft of the second roller assembly is coupled to an actuation system that includes a repositionable support member allowing translation of the shaft of the second roller assembly in a direction transverse to the draw direction of the glass ribbon, a pneumatic actuator controlling a position of the contact wheel of the second roller assembly in the direction transverse to the draw direction of the glass ribbon, and a pneumatic reservoir in fluid communication with the pneumatic actuator delivering fluid at an elevated pressure to the pneumatic actuator.

A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.

Methods and apparatus are provided for forming an initiation flaw () in the surface () of a glass sheet or glass ribbon (). The initiation flaw () is used in connection with a laser light beam () and a cooling area produced by a cooling nozzle () to from a score line () in the surface () of the sheet or ribbon (). The initiation flaw () is formed by a mechanical scoring head () which is carried by moving carriage () and which undergoes retrograde motion () relative to the carriage () so as to increase the time available for forming the initiation flaw ().

A component holder has a base and a component holding block extending upward from the base. The component holding block includes a pair of walls, the walls defining between them a channel dimensioned to closely receive an optical component cradled in a resiliently compliant member, such as a pad or a shaped component. An optical component is loaded into the channel by placing the optical component and a resiliently compliant member over the channel and wedging the optical component and the resiliently compliant member into the channel such that the optical component is cradled inside of the resiliently compliant member and such that the optical component and the resiliently compliant member are held in position in the channel by friction.
