A system includes a plurality of different types of fiber optic connectors each having at least one stub optical fiber configured to be spliced to at least one cable optical fiber. The system also includes a tool configured to: a) receive and detect the different types of fiber optic connectors; and b) set a threshold value for an acceptable indication of continuity for at least one splice between the at least one stub optical fiber and the at least one cable optical fiber based on which type of the fiber optic connector is received and detected.

The connector (C) comprises: an anchoring element (30) encircling a bolt (20); a semi-tubular clamp (40) having an anterior end portion (41), fitted and retained in the anchoring member (30), and a rear end portion (42) internally provided with inner teeth (43), which, by interference, an extension of the cable cover (CC) of an optical cable (1, 2) is inserted and held; a tubular housing (50) surrounding the anchoring element (30) and the clamp (40). The clamp (40) comprises, in a median region (44), defined between its front end portion (41) and rear end portion (42), at least one pair of side and mutually opposing inner claws (45, 46) between which a fiber jacket (CF) extension of the optical cable (1, 2) is radially engaged and axially retained by interference.

A fiber optic connector comprises a connector body having a front end and a back end, a boot having a rear portion extending beyond the back end of the connector body, and an actuation element received over at least the rear portion of the boot. The actuation element prevents the boot from moving from a rearward position relative to the connector body to a forward position relative to the connector body, but is also removable from the boot to allow such movement. Methods of installing fiber optic connectors with actuation elements and movable boots are also disclosed.

A fiber optic ferrule with rear holes and a guide pin clamp allows for changing guide pins in the field. The guide pin clamp has a forward clamp portion to engage the rear face of the fiber optic ferrule, a rearward clamp portion configured to engage the biasing spring, and a guide pin retaining plate. The guide pin retaining plate is movable from a first position to a second position to allow for the removal or insertion of guide pins.

A fiber optic adapter includes an adapter housing defining a connector port for mating with a fiber optic connector in either of two connector polarity orientations. A polarity cap is releasably securable to the adapter housing in either of two adapter polarity orientations, each of which only permits insertion of the connector in one respective connector polarity orientation. The changing polarity of the adapter is facilitated by removing the polarity cap from the adapter housing, inverting the polarity cap, and reinstalling the inverted polarity cap.

An object of the present invention is to provide, in a local-light coupling technique for improving efficiency of work, an optical fiber local-light coupling apparatus configured to hardly affect communication between an OLT and an ONU while causing light to leak from a coated optical fiber in such an amount that makes it possible to confirm a communication state. The optical fiber local-light coupling apparatus according to the present invention includes a first jig including a concave portion curved in a longitudinal direction with respect to a coated optical fiber, and a probe configured to receive leakage light leaking from the coated optical fiber being bent; a second jig including a convex portion curved in the longitudinal direction with respect to the coated optical fiber, the convex portion being configured to sandwich the coated optical fiber between the convex portion and the concave portion of the first jig; a pressing unit configured to apply pressing force in a direction in which the concave portion of the first jig and the convex portion of the second jig approach each other to form a bend in the coated optical fiber; and a reflective film configured to cover a surface of the concave portion of the first jig except for a leakage light passage portion through which, among the leakage light, reception leakage light to be received by the probe passes, and reflect and return the leakage light other than the reception leakage light to the coated optical fiber.

An optical fiber splicing tool of the invention include: an optical fiber splicing unit that includes: an optical fiber grasper that grasps a first optical fiber at a mechanical splice; and a guide target that is slidable along a guide provided at a connecting jig that fixes a second optical fiber to be butt-jointed to the first optical fiber; and a connecting jig that includes: a guide that guides the optical fiber splicing unit; and an optical fiber fixer that fixes the second optical fiber. The optical fiber splicing unit provides a first flexure width between one end side of the mechanical splice and the optical fiber grasper, and a second flexure width shorter than the first flexure width is ensured between the other end side of the mechanical splice and the optical fiber fixer when butt-jointing is carried out.

Ruggedized field terminated optical fiber connector systems comprising a field terminated connector assembly including a drop cable coupled to a connector, the drop cable having a custom length. The ruggedized field terminated connector system may further comprise a rugged front portion configured to slide over at least a portion of the field terminated connector assembly, and a rear connector body configured to couple to the rugged front portion. The rear body has a crimp ring and a grommet is slide into said crimp ring, and secured therein.

A portable device for attaching a connector to an optical fiber, the optical fiber having an end, the device comprising means for receiving the optical fiber at the end of the optical fiber; and a connector station for autonomously attaching the connector to the optical fiber.

A wedge device for use with a fiber optic connector comprises an insert body comprising a light transmissive material. The insert body defines a wedge portion integrally extending into a light pass structure, the light pass structure terminating in a single upper face distal from the wedge portion. For example, wedge device may be a unitary member formed entirely of the light transmissive material.
