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.

An optical receptacle includes: a first optical fiber; a second optical fiber connected to the first optical fiber by fusion splice; a ferrule including a fiber hole that holds an end of the first optical fiber; and a housing portion that houses therein: the ferrule, the first optical fiber, and a first portion of the second optical fiber. A fusion splice portion between the first optical fiber and the second optical fiber is disposed outside of the ferrule and within the housing portion.

Optical fiber stub having a first end and a second end, and a base on an outer surface of the stub body. A receptacle cap having a tubular body with a locking end and a receiving end, wherein an inner surface of the locking end includes an inner rim for receiving and securing a clip therein. A polymer insulating insert having a first plurality of clips on a first side and a second plurality of clips on the second side, wherein the first plurality of clips are configured to clip onto and secure the polymer insulating insert to the base of the stub body, and the second plurality of clips are configured to clip onto and secure the polymer insulating insert to the inner rim within the locking end of the receptacle cap.

A double flexible optical circuit includes: a flexible substrate supporting a plurality of optical fibers; a first connector terminating the optical fibers at a first end of the double flexible optical circuit; and a second connector terminating the optical fibers at a second end of the double flexible optical circuit. Each of the optical fibers is positioned in one of a plurality of separate extensions formed by the flexible substrate as the optical fibers extend from the first connector to the second connector. The first and second connectors are configured to be tested when the first and second connectors are connected through the double flexible optical circuit. The double flexible optical circuit is configured to be divided in half once the testing is complete to form two separate flexible optical circuits.

A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and the second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, a second diameter portion having a diameter of at least 250 microns and less than a diameter of a buffer, and a smooth and continuous transition between the first and the second diameter portions. The second diameter portion is positioned between the first diameter portion and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end toward the second diameter portion. In certain embodiments, another smooth and continuous transition can be provided between the taper shape and the second diameter portion. In certain embodiments, the axial passage is smooth and continuous between the first and the second ends of the body. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.

The present disclosure relates to a connector assembly and a corresponding method to cure bonding agent or adhesive in the connector assembly with light source(s) and without the addition of heat. Disclosed herein are various embodiments of bonding agents for use in adhering optical fibers to ferrules within optical connectors, and the methods for use thereof. Various embodiments of the bonding agents disclosed herein may have other desirable properties for the process of securing an optical fiber within a ferrule, such as, but not limited to, shortened process cycle time. Embodiments herein address these needs by monitoring the change in refractive index of a photocurable bonding agent at the interface between the photocurable bonding agent and a substrate or optical fiber, which is referred to as “back reflectance.” In particular, the methods described herein utilize back reflectance techniques to cure the photocurable material or bonding agent.

A connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes an optical fiber bundle including a plurality of optical fibers, at least one strength member, and a jacket surrounding the optical fiber bundle and the strength member. The connector assembly includes a rigid portion and defines a fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the fiber passage. The plurality of optical fibers undergo a transition from a ribbonized configuration to a loose, non-ribbonized configuration in the rigid portion of the connector assembly.
