Abstract: In accordance with the following description, an optical communication connector includes a ferrule having retractable alignment pins that are actuable between an extended position and a retracted position. For example, the connector may include an inner housing assembly having optical fibers and an outer housing positioned over the inner housing assembly. The outer housing is shaped to be removable from the inner housing assembly, which has a movable pin clamp mechanically coupled to alignment pins for aligning the connector with another connector. The pin clamp may be slid from a first position (corresponding to a male gender) to a second position (corresponding to a female gender). Separately or in combination with changing gender, the polarity of a communication connector may be changed due to its inclusion of an asymmetric polarity-changing feature that is actuable by an installer to change a polarity of the communication connector.

Abstract: A self-laminating rotating cable marker label is constructed of a transparent film having a first adhesive area, an adhesive-free smooth area, and a second adhesive area. A print-on area forms one side of the transparent film, the print-on area adapted to receive indicia identifying the cable about which the marker label is applied. A perforation extends across the transparent film providing a line of separation of the transparent film. When wrapped around a cable, the second adhesive area overlies the print-on area such that the cable identifying indicia is visible through the transparent second adhesive area. As the transparent film is wrapped around the cable, the first adhesive area adheres to the cable. The remainder of the transparent film is rotated, breaking the perforation, whereby the smooth area of the film in contact with the cable provides smooth rotation of the label around the cable.

Abstract: A low latency free-space optical data communication channel has at least one optical collimator for transmitting an optical communication signal in the form of a parallel beam across a free-space channel. The input of the collimator includes a connectorized optical fiber pigtail for connecting said collimator to a glass optical fiber carrying the signal to be transmitted across the free-space channel. The optical beam propagates in free space along the longitudinal axis of a raceway, which is at least partially enclosed. The second optical collimator located at the distant end of said raceway, is positioned to receive the free-space optical communication signal. The received signal is focused into a second optical fiber pigtail at the output side of the collimator, thereby resulting in a pigtailed free-space low latency optical channel link.

A mode field diameter (MFD) of the PCF hollow core section is in the range of 16 to 19 microns, the length of the PCF is between 1 cm to 10 cm, the MMF has 50+2 microns core diameter, the SMF has a 6-9 microns core diameter, and the coupling between the PCF mode to the MMF fundamental mode is maximized.

Abstract: An elongated object label applicator has a driver operably connected to a wrapping mechanism. The wrapping mechanism has a plurality of guide rollers spaced about a central portion. A belt is tensioned around the guide rollers and across an opening in the central portion through which an object to labeled is received. The belt is deflectable against an elastic force such that the belt can be recessed with the central portion by a force provided by the object to be labeled. The wrapping mechanism is driven by the driver to rotate the guide rollers about an axis of rotation of the wrapping mechanism passing through the central portion. The wrapping mechanism orbits the object to be labeled located within the central portion.
