The present disclosure relates to a fiber optic connector designed to improve the insertion of an optical fiber within the fiber optic connector. The fiber optic connector may include a lead-in tube that makes the insertion of an optical fiber easier. That is, the lead-in tube may be molded over a ferrule hub to fully encapsulate a rear end thereof such that the optical fiber does not snag or hang up during insertion.

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.

An optical power detection system comprises a sensor and a reader. The sensor is configured to detect light in the cladding of an optical fiber. The sensor is positioned both within a ferrule of the optical fiber and proximate the cladding. The sensor is additionally configured to produce an output signal representative of the detected light. The reader is electrically coupled to the sensor and is configured to receive the sensor output signal. The reader is additionally configured to operation on the output signal to produce a corresponding visual and/or audible indication of the optical power in the optical fiber.

Optical power detector and reader

A telecommunications assembly includes a chassis and a plurality of fiber optic splitter modules mounted within the chassis. Each splitter module includes at least one fiber optic connector. Within an interior of the chassis are positioned at least one fiber optic adapter. Inserting the splitter module through a front opening of the chassis at a mounting location positions the connector of the splitter module for insertion into and mating with the adapter of the chassis. The adapters mounted within the interior of the chassis are integrally formed as part of a removable adapter assembly. A method of mounting a fiber optic splitter module within a telecommunications chassis is also disclosed.

The present disclosure relates to an epoxy tube for an optical fiber connector. The tube can be mounted to a ferrule hub by a snap fit connection. The connection between the tube and the ferrule hub allows for float of the epoxy tube where the epoxy tube is not rigidly attached to the hub. The epoxy tube can be configured to move about an arc of rotational circular movement while remaining linear such that the epoxy tube does not bend or transfer forces to the hub.

The present disclosure provides a system and method for connecting an optical fiber to a ferrule. The system and method facilitate the process of epoxying the optical fiber in a manner that avoid inadvertently adhering the fiber to the side of a connector housing, which can result in breakage of the optical fiber when in the field. The system and method provide a mechanism for easily epoxying the optical fiber to the ferrule while still allowing for sonic radial movement of the optical fiber within the connector housing, which is desirable. The system and method incorporate an end cap that centers the optical fiber in the connector housing during the connection process and also acts as a strain relief when in the field.

Fiber optic connector with rear cap

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 second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, and a second diameter portion having a diameter of at least 250 microns and less than a diameter of the buffer, the second diameter portion positioned between the first diameter and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end to the second diameter portion. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.

Dual inner diameter ferrule device and method

Aspects and techniques of the present disclosure relate to fiber optic connectors with features that help eliminate the potential of a capillary effect or epoxy wicking. The fiber optic connector may include an epoxy tube with segments that define a pocket in an area that helps to prevent capillary action between components that are otherwise closely positioned.

Fiber optic connector with anti-wicking epoxy tube

A fiber optic connector with a hub extension positioned on the hub of the connector. Prior to assembly of the connector with the rear boot, the hub and ferrule assembly can be pushed backward within the front and rear housings to clear an anti-rotation portion of the front housing and turned for tuning. After complete assembly of the rear boot, the hub extension bottoms out against the boot prior to the hub and ferrule assembly disengaging the anti-rotation portion of the front housing, thereby maintaining the tuned position.

Tuned fiber optic connector

The present disclosure relates to fiber optic components and structures for use in building fiber optic networks using an indexing architecture. In certain examples, fan-out structures are used.

Indexing architecture including a fan-out arrangement

An optical fiber cable assembly comprising an optical fiber slidably enclosed within a hollow tubing, both the fiber and the tubing having corresponding first and second ends. The cable is terminated with the first and second ends of the tubing and the fiber constrained with respect to each other such that fiber and the tubing are approximately the same length when the cable is at a first temperature. The tubing is made of a material which contracts more than the optical fiber when the cable is exposed to temperatures below the first temperature, such that the fiber is longer than the tubing and excess fiber length is formed. An intermediate portion of the tubing permits the excess fiber length to accumulate without bending in a radius smaller than a minimum bend radius

Fiber optic cable and furcation module

A fiber alignment device is provided that includes a curable refractive index-matching gel that exhibits self-cleaning and self-healing characteristics upon multiple cycles of insertion and removal of an optical fiber.
