A cleaving mechanism (20) and related method is adapted to cleave an optical fiber (10) and thereby produce a cleaved end on the optical fiber. The cleaving mechanism (20) includes a fixture (40), a cleave tool (60) for cleaving the optical fiber, and a clamp assembly (80). The clamp assembly (80) may hold the optical fiber without substantial twisting of the optical fiber (10). The fixture and/or the clamp assembly (80) may include a pair of leaf springs (92) that contact and bend around the optical fiber (10) to secure the optical fiber (10) in a clamped position.
A hinge structure (2202) for pivotally mounting a first telecommunications element (2256) to a second telecommunications element (2224/2210) includes a hinge pin (2203) provided on the first element (2256) and a hinge pin receiver (2204) provided on the second element (2224/2210). The hinge pin (2203) defines a notch (2206) separating the pin (2203) into two pin halves (2205). The hinge pin receiver (2204) defines two sets of opposing surfaces (2214), the two sets (2214) separated by a divider (2212), the divider (2212) configured to be accommodated by the notch (2206) when the hinge pin (2203) is inserted into the hinge pin receiver (2204), wherein each opposing surface set (2214) defines a slot (2213) for receiving each pin half (2205).
A system for monitoring a signal on an optical fiber includes a fiber optic connector having a housing couplable to a receptacle. An optical fiber that transmits a first optical signal has first fiber core at least partially surrounded by a cladding and has a first end terminating proximate the housing. The first optical signal is transmitted along the first fiber core. An optical tap has a first tap waveguide arranged and is configured to receive at least part of the first optical signal as a first tap signal. The first tap waveguide comprises an output port for the first tap signal for directing the tap signal to a detector unit. In other embodiments, a detector unit detects light from the optical signal that is propagating along the fiber cladding.
