摘要： Systems and methods of aligning an optical interface assembly with an integrated circuit (IC) are disclosed. The method includes emitting light from an optical transmitter, passing the emitted light through the optical interface assembly in a first direction, and reflecting the emitted light from a reflective surface disposed immediately adjacent a front end of the optical interface assembly to define reflected light that travels back through the optical interface assembly in a second direction that is substantially opposite the first direction. The reflected light is received by an optical receiver that generates in response a receiver signal. The relative position of the optical interface assembly and the IC is adjusted to achieve an aligned position based on the receiver signal. The disclosure is also directed to a test plug for aligning an optical interface assembly to the IC.

摘要： Mirror systems securing optical fibers to ferrules by thermally securing bonding agents within fiber optic connector housings are disclosed, along with related methods and assemblies. A fiber optic connector includes an optical fiber secured within a ferrule by a temperature-sensitive bonding agent to prevent attenuation-causing movement. The bonding agent is activated (e.g., cured) by heat provided by laser energy incident upon the ferrule, which is at least partially disposed within a fiber optic connector housing and which may be damaged by the laser energy. By shaping and disposing at least one mirror of a mirror system, the laser energy may be reflected to be incident upon the ferrule in a controllable intensity distribution. In this manner, the laser energy may be absorbed uniformly or substantially uniformly along a partial length of the ferrule extending into the housing to accelerate securing of the bonding agent while avoiding damage to the housing.

摘要： Optical receptacles having compliance for facilitating alignment with fiber optic connectors during insertion, and related components, systems and methods are disclosed. In one example, an optical receptacle disposed in a receptacle optical assembly optically connects to a fiber optic component, for example, a ferrule, for facilitating transmission of an optical signal from the optical receptacle to the exemplary ferrule. A support interface between the optical receptacle and receptacle housing contains a compliance feature that permits the optical receptacle to move with respect to the receptacle housing during insertion of the fiber optic connector. An insertion force of the fiber optic connector causes the optical receptacle to be able to move into optical alignment with the connector during insertion of the fiber optic connector, thereby moving ferrule(s) of the fiber optic connector into optical alignment with the ferrule(s) of the optical receptacle.

摘要： A fiber optic ribbon cable includes a stack of fiber optic ribbons, strength members surrounding the stack, and a jacket defining an exterior of the cable. The jacket forms a cavity through which the stack and the strength members extend. The stack has a bend preference, but the strength members are positioned around the stack or are flexible in bending such that the strength members do not have a bend preference. Furthermore, the jacket is structured such that the jacket does not have a bend preference. The cavity is sized relative to the stack in order to allow the stack to bend and twist within the cavity with respect to the jacket as the cable bends, facilitating movement of the optical fibers of the fiber optic ribbons to low-stress positions within the cavity and decoupling the bend preference of the stack from transfer to the jacket.

摘要： Disclosed are optical ports and devices having a minimalist footprint. Specifically, the optical ports and devices have a footprint where the optical elements are exposed at a frame of the device. Additionally, a frame of the device provides a portion of the mating surface for engaging a complimentary optical plug during mating with the optical port on the device. This minimalist footprint advantageously allows for a smaller portion of the optical port to be exposed to the environment and subject to damage and/or wear. Further, the optical port provides a clean and sleek optical port on the device with a relatively small surface that may be cleaned or wiped by the user as necessary.

摘要： Embodiments for processing of gradient index (GRIN) rods into GRIN lenses attachable to optical devices, components, and methods are disclosed. A cylindrical GRIN rod comprises an optical axis and a longitudinal axis at a center axis, where the index of refraction may be greatest at the optical axis. The GRIN rod includes GRIN lenses along the longitudinal axis. The GRIN lenses include a first optical surface and a second optical surface opposite the first optical surface. Separation processes and devices may separate the GRIN lenses from the GRIN rods and these processes may be automated. Other processes may polish the first and the second optical surfaces. A gripper may insert the GRIN lens into an optical device.

摘要： Calibration of optical time domain reflectometry optical loss measurement in optical fibers having potentially dissimilar light backscattering properties is disclosed. For example, an optical time domain reflectometer (OTDR) can be employed to perform a single-ended optical loss measurement on an optical fiber before and after joinder (e.g., a splice) to determine the efficiency of the joinder. The individual optical fibers provided in a joined optical fiber may have dissimilar backscatter light collection efficiencies resulting in an erroneous OTDR optical loss measurement, because an OTDR assumes the backscatter light collection efficiency of the joined optical fiber is identical before and after joinder. An OTDR calibration factor is first determined before an OTDR optical loss measurement of the joined optical fiber is made. The OTDR calibration factor is used to correct any error in an OTDR optical loss measurement of the joined optical fiber.

摘要： Embodiments disclosed herein include fiber optic connectors employing a movable optical interface connected by optical fibers to a fiber optic cable, components and methods. In one embodiment, the movable optical interface moves between an extended position for cleaning by the user of the movable optical interface and a retracted position to optically connect the fiber optic connector to an optical device in a mechanically-secure manner. Because the fiber optic cable employs the movable optical interfaces, embodiments described herein involve one or more fiber protection features to prevent optical fiber attenuation and/or damage to the end portions of the optical fibers.
