摘要： 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.

摘要： In an optical connector ferrule, a side surface of the front end portion is connected to a front end surface of the front end portion and extends in a direction intersecting the front end surface. The flange portion is connected to the front end portion on an opposite side of the front end surface. The flange portion protrudes from the front end portion in a direction along the front end surface. An optical fiber hole opens in the front end surface and extends in an intersecting direction intersecting the front end surface. The window opens in the side surface. A shortest distance between a connection position where the flange portion and the front end portion are connected to each other and a portion which is closest to the front end surface in the edge is less than or equal to a width of the flange portion in the intersecting direction.

摘要： Methods of assembling polarization-maintaining (PM) optical fiber assemblies includes inserting optical fibers through channels of a receptacle with ends of extending past a front face of the receptacle. The first ends are radiated causing the initial fiber diameter to expand and results in an enlarged fiber diameter and forms an enlarged portion for a desired length along the PM optical fibers. The birefringent elements of the optical fibers are aligned to present a desired orientation and the optical fibers are further retracted until the enlarged portions abut the corresponding channels to mechanically lock the orientation of the optical fibers. The optical fiber assembly is further finished to maintain the polarity from the first end to a second end.

摘要： An optical ferrule assembly includes an optical ferrule including an attachment area, a light input surface and a light output surface; an optical fiber having a fiber end where the light input surface and the fiber end defines a gap therebetween substantially filled with an adhesive, such that light propagating along the optical fiber and having a peak intensity I1≥3 GW/m2, exits the fiber end and enters the optical ferrule through the light input surface after traversing the gap through the adhesive, and exits the optical ferrule through the light output surface. The exiting light has a first beam size, such that after at least 100 hours of aging of the optical ferrule assembly, any change in the first beam size due to a photodegradation of the adhesive is no more than about 10%. The adhesive can be prepared by photocuring an optical adhesive formulation.

摘要： Methods and devices for assembling a fiber optic connector are provided. A device supports at least one fiber optic connector. The connector has an optical fiber inserted through the ferrule so that an exposed portion is disposed outside of the ferrule. Residual epoxy on the exposed portion is cured prior to physically manipulating the optical fiber within the ferrule. The device includes at least one heating chamber and a heat shield for curing of the residual epoxy.

摘要： A coupling unit includes a light coupling element comprising an attachment area for receiving and permanently attaching to a plurality of optical waveguides. One or more grooves are provided at the attachment area. Each groove is configured to receive an optical waveguide and defined by a bottom surface, a first region, a second region, and an opening. The first region is defined between the bottom surface and the second region. The first region in cross section has substantially parallel sidewalls separated by a spacing. The second region is disposed between the first region and the opening. A width of the opening is greater than the spacing.

摘要： Assemblies, optical connectors, and methods for forming fiber arrays using laser bonded optical fibers are disclosed. In one embodiment, a method of forming a fiber array includes placing an optical fiber on a surface of a substrate, directing a laser beam into the optical fiber disposed on the surface of the substrate, melting, using the laser beam, a material of the substrate to create a first laser bond zone between the optical fiber and the surface of the substrate, applying an adhesive to the optical fiber and the substrate to create an adhesive bond zone between the optical fiber and the surface of the substrate, and cutting the optical fiber and the substrate to create a first section of the fiber array and a second section of the fiber array. The first section of the fiber array includes a first portion of the optical fiber, a first portion of the substrate, a first portion of the adhesive bond zone, and the first laser bond zone, and the second section of the fiber array includes a second portion of the optical fiber, a second portion of the substrate, and a second portion of the adhesive bond zone.

摘要： 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.
