Abstract: A fiber cleaver having a displaceable fiber guide for aligning and guiding an optical fiber is disclosed. Generally, the fiber cleaver comprises a pair of clamps that may articulate between a retracted position and a clamping position. A displaceable fiber guide directs the optical fiber as it travels along an internal path of the fiber cleaver. The fiber guide translates between a loading position and a clamping position. When the clamps are securing the optical fiber to the internal path, a linear actuator may be depressed in order to translate the fiber guide and ultimately direct the optical fiber toward a scoring blade to cleave the fiber. The fiber guide is sized and shaped such that a predetermined length of optical fiber will remain after cleaving.
