Fiber optic connectors, cable assemblies and methods for making the same are disclosed. 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, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.

An optical connector assembly includes a spring, a ferrule, a first housing, and a second housing connected to the first housing. The ferrule includes a ferrule body and a lens. The ferrule body defines a fiber receiver configured to receive optical fibers of an optical cable and a first spring receiver configured to receive the spring. The lens is arranged to optically communicate light propagated by the received optical fibers for free-space optical communication. The first housing defines a first opening configured to slidably receive and guide the ferrule for movement along a first longitudinal axis. The second housing defines a second opening configured to receive the optical cable therethrough along a second longitudinal axis, and a second spring receiver configured to receive the spring. The spring biases movement of the ferrule in the first housing away from the second housing.

An optical rotary junction module for an OCT system according to the present invention includes an OCT connection part having a screw thread formed on an outer peripheral surface thereof, the OCT connection part being connected to an OCT system configured to produce light, a connecting/fixing part having a screw thread formed on an inner peripheral surface thereof and screw-coupled to and engaging with the screw thread formed on the outer peripheral surface of the OCT connection part, a first housing having a screw thread formed on an inner peripheral surface of one end thereof and a screw thread formed on an inner peripheral surface of the other end thereof, the first housing having one end screw-coupled to the connecting/fixing part, a second housing screw-coupled to the screw thread formed on the inner peripheral surface of the other end of the first housing, a hollow motor inserted into the second housing and configured to generate rotational power, and an adapter configured to be coupled to an imaging catheter configured to be inserted into a blood vessel of a human body and transmit light received from the OCT system. The optical rotary junction module has the effects of reducing noise generated during high-speed rotation, and preventing failure caused by abrasion or the like. Moreover, the module may be structurally simplified and reduced in size, and the product cost per unit thereof may be lowered by minimizing the components.

Multiports having connection ports with securing features that cooperate with flexures and methods for making the same are disclosed. In one embodiment, a multiport comprises a shell, at least one connection port, at least one flexure and at least one securing feature. The at least one connection port comprises an optical connector opening and a connection port passageway, and the at least one flexure is associated with the at least one connection port. The at least one securing feature is associated with the at least one connection port, where the at least one securing feature cooperates with the at least one flexure.

A cleaning tool includes: a head including: a pressing part that presses a cleaning element against an object to be cleaned in a pressing direction, and having a first dimension in a width direction orthogonal to the pressing direction; and a neck part having a second dimension smaller than the first dimension in the width direction; and a housing that houses the head such that the pressing part and the neck part protrude from the housing in the pressing direction. A length of the housing in the width direction is equal to or greater than a length of protrusion of the pressing part protruding from the housing in the pressing direction.

Fiber optic connectors, including SC and MPO connectors that include a strain relief boot operably coupled with a release mechanism for releasing the connector from an adapter or other termination device or receptacle. The strain relief boot can be operably coupled to move axially together with the outer housing of the connector.

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. Such a feature may actuated by being moved from a first position to a second position relative to the communication connector.

An optical fiber alignment assembly may comprise an alignment fixture including a groove configured to engage first and second optical fiber ferrules, a first clamping mechanism configured to selectively apply a force on the first optical fiber ferrule to constrain motion of the first optical fiber ferrule within the groove, and a second clamping mechanism configured to selectively apply a force on the second optical fiber ferrule to constrain motion of the second optical fiber ferrule within the groove.
