Abstract: An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical waveguide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the waveguide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.

Abstract: A first optical device is adapted to couple to a second optical device along a coupling direction and includes two spaced apart pairs of leading and trailing pads, such that when the first optical device lands and slides on a landing surface of the second optical device to optically couple to the second optical device, and for each pair of leading and trailing pads, the leading pad prevents any debris on the landing surface from collecting on the trailing pad. Upon full coupling of the first optical device with the second optical device, the leading pads do not make contact with the landing surface. The first optical device may be, for example, an optical ferrule or a cradle having a recess adapted to receive an optical ferrule.

Abstract: A light coupling unit includes a first major surface comprising one or more substantially parallel first grooves oriented along a first direction for receiving one or more optical waveguides. A second major surface for slidably contacting a mating light coupling unit comprises an optically transmitting window for propagating an optical signal therethrough, and a region of second grooves and lands configured to capture particulate contaminants in the second grooves.

Abstract: An optical connector (100) comprises one or more optical cables (110) disposed within a housing (120). Each optical In cable (110) includes an array of at least one optical waveguide (111) and at least one optical ferrule (112) attached to the array of optical waveguides (111). The housing (120) includes a first housing portion (121) and a second housing portion (122) engaged with the first housing portion (121). The second housing portion (122) comprises at least one carrier (130) and one frame (140). The carrier (130) and frame (140) of the second housing portion (122) are configured to support the one or more optical cables (110). The first housing portion (121) and the second housing portion (122) are configured such that mechanical engagement of the first housing portion (121) with the second housing portion (122) moves the carrier (130) relative to the frame (140). Movement of the carrier (130) relative to the frame (140) causes a bend in each optical waveguide (111) and rotation of each ferrule (112). The bend provides a predetermined spring force of the optical waveguides (111) at a predetermined angle of the ferrule (112).

Abstract: An optical connector (100) includes a housing (112) configured to contain one or more optical ferrules (121) disposed within the housing and accessible through an opening at a mating end of the housing. A cover (130) is disposed at the mating end, the cover configured to be rotated about a pivoting axis between a closed position an open position. An actuator (135, 136) is configured to cause the cover to rotate about the pivoting axis from the closed position to the open position.

Abstract: An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.

Abstract: An inspection device for an optical ferrule includes one or more reflectors. Each reflector has a mating surface and a mirror disposed at an oblique angle with respect to the mating surface. Each reflector is configured to mate with the optical ferrule when the optical ferrule is disposed within a housing of an optical connector. When the mating surface of the reflector is in mated contact with the mating surface of the optical ferrule, the mirror is positioned to provide a reflected view of at least a portion of a mating surface of the optical ferrule.

Abstract: A unitary optical ferrule is molded to include one or more elements for receiving and securing one or more optical waveguides one or more elements for affecting one or more characteristics of light from the optical waveguide while propagating the light within the ferrule. The optical ferrule also includes one or more first alignment features and one or more second alignment features that, when the ferrule is mated with a mating ferrule, each controls alignment of the ferrule with the mating ferrule along three mechanical degrees of freedom. The surface of the optical ferrule can be divided along the thickness axis into a first section and an opposing second section, wherein the first section of the surface includes the receiving and securing elements, the light affecting elements, and the first alignment features and the second section of the surface includes the second alignment features.
