A communications connection system includes an adapter module defining at least first and second ports and at least one media reading interface mounted at one of the ports. The first adapter module is configured to receive a fiber optic connector at each port. Some type of connectors may be formed as duplex connector arrangements. Some types of adapters may include ports without media reading interfaces. Some types of media reading interfaces include contact members having three contact sections.

A dual polarity optical fiber adaptor that can accommodate and mate with optical fiber connectors with dual polarity is provided. In one example, a fiber optic adaptor module includes a housing having a top wall, a bottom wall, a first sidewall, and a second sidewall connecting the top wall and the bottom wall, the top and bottom walls and the first and second sidewalls defining an interior region in the housing, a partition wall disposed in the interior region connected between the top wall and the bottom wall, the partition wall defining one or more adaptors in the housing each having a connector connection port formed therein, wherein the partition wall has a center portion sandwiched between a first portion and a second portion, and a protruding tab formed in the center portion protruding outward from a first surface and a second surface of the first and the second portion, wherein the first and the second surfaces are vertically aligned.

A surgical laser tool (150) comprises an output member (162) that includes an output laser fiber (164), a probe tip (132), and electrical contacts (240). The probe tip is attached to a distal end (171) of the output laser fiber. Electromagnetic energy (102) transmitted through the output laser fiber is discharged through the probe tip. The electrical contacts are supported at a proximal end (169) of the output member.

In one aspect, a handheld lighting system is disclosed, which comprises a handheld housing extending from a proximal end to a distal end, and a light module disposed at least partially in the housing. The handheld lighting system further includes a removable and replaceable power module that is coupled to the housing (e.g., it is at least partially disposed within the housing) and is electrically coupled to the light module, e.g., through a pair of electrical leads, for providing electrical power thereto. Light intensity from the light module may be controlled from a knob on the power module. Various adapters can allow the lighting system to attach to a multitude of medical, industrial, dental or veterinary endoscopes or other instruments.

The invention generally relates to optical fibers, and, more particularly, to hollow-core optical fibers and cables for use in high-speed data transmission, including transmission of telecommunications data, and methods of manufacturing such hollow-core optical fibers and cables.

An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.

An assembly of two fiber optic ferrules allows for the mating of a CWDM fiber optic ferrule with a non-CWDM fiber optic ferrule. The CWDM fiber optic ferrule has optical fibers that carry optical beams with at least two different wavelengths, which the non-CWDM ferrule has optical fibers that carry only one wavelength. The CWDM fiber optic ferrule causes the optical beam to make at least one 90 degree turn. The non-CWDM fiber optic ferrule has a lens pitch that matches the CWDM ferrule.
