In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end. The fiber optic connector may be converted from a first footprint to a second footprint by a conversion housing that fits about a portion of the housing. The optical connectors disclosed may be tunable for improving optical performance and may also include a spring for biasing the ferrule to a forward position as desired.

An adapter assembly is formed from an adapter housing with a recess configured to accept an adapter panel hook. The adapter assembly is secured within a panel using the adapter panel hook. The adapter panel hook has opposing side portions connected by a joining plate. Each side portion has an elastic pawl with opposing elastic members. The elastic members are configured to be secured between the adapter outer housing and panel wall opening to reduce vibration at the adapter housing.

A system including ruggedized optic fiber cable assembly for use with an arc detection relay to protect electrical components from faults resulting in an arc flash. The cable assembly includes a pair of ruggedized ST connectors located at opposite ends of a ruggedized optical fiber cable. The cable includes an optical fiber core surrounded by a transparent gel layer and a transparent jacket surrounding the gel layer. Each ST connector includes a boot formed of a resilient material to provide shock absorption for the portion of the optical fiber cable extending through it. An accessory electronic cable is also provided, as are couplers, adapters for mounting the couplers onto walls, and sleeves with air pockets to enhance the ruggedness of the cable at points of stress, e.g., bends.

Devices having at least one connector port associated with a rotating securing features are disclosed. A device for making optical connections comprising a shell, at least one connection port, and at least one rotating securing feature is disclosed. In one embodiment, the at least one connection port is disposed on a device with at the least one connection port comprising an optical connector opening extending from an outer surface of the device into a cavity of the device and defining a connection port passageway. The at least one rotating securing feature is associated with the connection port passageway, and the at least one rotating securing feature is secured to the device along a rotational axis that is not aligned with a longitudinal axis of the at least one connection port.

A field-assembly optical connector includes an inner sleeve module, a connector frame housing the inner sleeve module, and a cable boot coupled to the inner sleeve module to protect a sheath of an optical fiber. The inner sleeve module includes a sleeve body having a sleeve, an intermediate connector fitted on the sleeve body and having protrusions, a spring fitted on a threaded portion of the sleeve body, a fixing ring screwed to the threaded portion of the sleeve body, and a ferrule stub inserted into the sleeve body through the fixing ring. A cable boot is fixed to the sleeve body and is coupled to the intermediate connector to be moveable within a predetermined range.

An optical communication system comprises N server racks, first and second distribution frames, and first and second optical fiber cables. Each of the first and second optical fiber cables has N optical connector groups for racks and an optical connector group for distribution frame including M optical connectors. The closer the number of an optical connector of the M optical connectors is to the last number, the longer a wiring distance from the optical connector group for distribution frame to a corresponding optical connector group of the N optical connector groups for racks in the first optical fiber cable. The closer the number of an optical connector of the M optical connectors is to the last number, the shorter a wiring distance from the optical connector group for distribution frame to a corresponding optical connector group of the N optical connector groups for racks in the second optical fiber cable.

A termination for a fiber optic cable, includes an optical connector for a fiber optic member, a collar having a hollow interior in which at least part of the optical connector is positionable, and a retaining clip positionable with respect to the collar at a location to block exiting of the optical connector from the collar. A stop in the collar limits insertion of the connector in the collar. The termination may be assembled and installed in the field.

A method of assembling a cable termination assembly, includes positioning at least part of a cable and connector in a hollow collar, and inserting a retainer clip through an opening in a wall of the collar in position to block withdrawing of the connector from one end of the collar. Additionally, a resilient cover is positioned on the collar to provide a watertight connection with another device with which the cable termination assembly may be attached. The method may be carried out to assemble and install the cable termination assembly in the field.

A delivery system extends from a laser radiation source for connecting to a medical device that utilizes the laser radiation for medical treatment. The delivery system comprises an optical fiber connecting to a male launch connecter. The male launch connector having a body portion with the optical fiber fixed or constrained therein and the optical fiber terminating at a male ferrule with a forward directed fiber facet, the male ferrule may be cantilevered within the body portion by the optical fiber line providing freedom of movement of the male ferrule. The launch connector engages a receiving connector on the medical device first with mechanical connection portions and then more finely aligning optical connection portions by the male ferrule self aligning in a female ferrule with cooperating tapered surfaces. The male portion may fully seat in the female portion with cooperating cylindrical surfaces.

A connector assembly for a hybrid cable includes: a housing, comprising a base; at least one discrete connector mounted in the base or at least one connector that is at least partially integrated in the base, configured to receive at least one fiber from the hybrid cable; and at least one electrical interface, configured to receive at least one wire from the hybrid cable.

An optical fiber plug adapted to be connected to an optical fiber socket and a first optical fiber cable includes a plug sleeve unit, a plug unit, a plug guiding unit, and a coupling unit. The coupling unit includes a coupling seat, a coupling ring, and a coupling cover movable between a locked position and a released position. When the coupling cover is at the locked position, the optical fiber plug is locked to the optical fiber socket by the coupling ring. When the coupling cover is moved from the locked position to the released position, the coupling ring is urged resiliently by the coupling cover to release the optical fiber plug, thereby permitting separation of the optical fiber plug from the optical fiber socket.
