摘要： An optical connector of one embodiment includes an optical fiber, a ferrule assembly, and a housing provided with a positioning part on an inner wall surface for suppressing a fluctuation in an aligning state of the optical fiber with respect to the housing. The positioning part includes an inclined surface and a facing surface which contact a part of the ferrule assembly. The ferrule assembly includes a ferrule, and a sleeve member. The sleeve member is constituted by a sleeve and a flange which has edges contacting the inclined surface and the facing surface respectively. Of an outer peripheral portion of the flange, a portion including the edges facing at least one of the inclined surface and the facing surface includes a set including a deformation absorbing part and two contact portions disposed on both sides of the deformation absorbing part.

摘要： A fiber optic cassette may include a cassette body defining a front end, a rear end, and an enclosed interior. Multiple identical apertures are included on the front end of the cassette body, where each aperture is configured to accept a fiber optic adapter. The cassette may further include an optical component located in an enclosed interior of the cassette body and configured to process a signal received from a fiber optic connector coupled to one of the fiber optic adapters, a crimp tube mounted to the front end of the cassette body, and at least one fiber optic cable attached to the crimp tube, extending from the cassette and configured to carry the signal processed by the optical component. The fiber optic cable may include a jacket, a strength member crimped to the crimp tube, and optical fibers extending past the crimp tube into the interior of the cassette body, wherein the mounting structure for mounting the crimp tube to the cassette body is receivable within one of the identical apertures.

摘要： A fiber optic adapter block is disclosed. The fiber optic adapter block includes at least three fiber optic adapters provided in a stacked arrangement extending widthwise in a longitudinal direction, wherein every other adapter of the at least three fiber optic adapters is staggered in a front to back direction with respect to an adjacent adapter such that front ends of the every other adapter of the at least three fiber optic adapters are aligned at a first depth and a front end of the adjacent adapter is at a second depth that is different than the first depth.

摘要： An optical fiber connection structure includes: a multi-core fiber; a plurality of single-core fibers; a first lens having a focal length of f1 (mm); and a second lens having a focal length of f2 (mm). A core pitch of the multi-core fiber is P1 (μm), a mode field diameter on the first end face of each core is MFD1 (μm), a core pitch of multiple single-core fibers is P2 (μm), a mode field diameter of a light beam on the second end face of each core is MFD2 (μm), and the following formulas are satisfied.
(P1/P2)×0.9≤f1/f2≤(P1/P2)×1.1, and
(P1/P2)×0.9≤MFD1/MFD2≤(P1/P2)×1.1-

摘要： A fiber optic cable slack management module includes a base defining a first cable management spool, an outer face of which is configured to contact cables when cables are pulled away from the base and a second cable management spool, within which the first cable management spool is located. An inner face of the second cable management spool is configured to contact cables when cables are in a relaxed, non-pulled state. The fiber optic cable slack management module defines a cable exit adjacent the first cable management spool and defined at least partially by the inner face of the second cable management spool, the cable exit defined by a channel positioned between the first and second cable management spools.

摘要： A ferrule for an optical fiber connector has an external surface for alignment with a complementary surface of an alignment sleeve (i.e., the inside surface of a generally cylindrical or tubular sleeve). The external surface of the ferrule is generally cylindrical, having a sectional contact surface profile that is generally oval in shape. More specifically, a plurality of points of contact between the ferrule and the sleeve are defined along a curve in cross-section, wherein the center of curvature at each of the contact points along this contact point curve (i.e., the curve containing contact points that contribute to alignment) does not lie in the plane of the axis of the array of optical fibers.

摘要： A fiber optic plug, suitable for multi-core fiber (MCF), is structured to hold satellite cores of the MCF in a precise angular positions so as to attain suitable alignment with satellite cores of a mating connector. The plug includes features to permit a ferrule holding the MCF to move longitudinally relative to the connector's housing, so that a spring may control a mating force to an abutting ferrule of a mating connector. The ferrule may be held by ferrule barrel having splines projecting away from an outer peripheral surface. The splines may slide longitudinally within notches of the connector housing or a strength member attached to the connector housing. The notches and splines have a tight tolerance, so that the satellite cores remain in a desired, set angular position.

摘要： A telecommunication enclosure includes an environmentally sealed housing having an interior volume. The sealed enclosure includes a housing wall defining an opening that extends from the interior to an exterior of the enclosure, the housing wall defining interior threads within the opening. A port-defining element mounts within the opening, the port-defining element defining exterior threads that are threadingly mated with respect to the interior threads to retain the port-defining element within the opening. The port-defining element defines a connector port for receiving a hardened fiber optic connector.

摘要： The invention comprises a photonic crystal fiber (PCF) assembly comprising a PCF and at least one ferrule structure. The PCF has a center axis and comprises a core region and a cladding region and a first fiber end section with a first fiber end. The ferrule structure has a center axis and is mounted to the first fiber end section. The ferrule structure comprises an inner ferrule arrangement and an outer ferrule arrangement surrounding the first fiber end section. The inner ferrule arrangement comprises an inner ferrule front section proximally to the first fiber end and an inner ferrule rear section distally to the first fiber end, and each of the inner ferrule sections have an inner diameter and in at least a length thereof fully surrounds the PCF. The inner ferrule rear section is anchored in an anchor length section to the first fiber end section and the inner ferrule front section supports the first fiber end section proximally to the first fiber end.

摘要： An optical fiber connector sub-assembly for an optical fiber connector includes a ferrule configured to hold an optical fiber therein along an axis of the ferrule and a ferrule holder configured to hold the ferrule. The ferrule has an end face at which the optical fiber is terminated, and the ferrule holder includes a base in which the ferrule is configured to be seated. The sub-assembly includes a ferrule basket including an inner sleeve slidably coupled with an outer sleeve and configured to isolate a front end of the connector from a rear end of the connector such that the ferrule is isolated from movement of the rear end of the connector. The ferrule basket is configured to receive the ferrule holder therein.
