Abstract: A fiber cleaver (100) for cleaving an optical fiber (106). A monobloc fiber handling element (116) defines a pair of spaced apart fiber holding portions (120) each defining an elongated fiber receiving aperture (122) for receiving a respective part of the optical fiber (106) thereinto. The fiber handling element (116) is deformable between open, closed and tensing configurations. In the open configuration, the fiber receiving apertures (122) extend coaxially and the fiber receiving apertures (122) have an open width. In the closed configuration, the fiber receiving apertures (122) have a closed width smaller than the open width. In the tensing configuration, the fiber receiving apertures (122) have the closed width and an inter-aperture distance is larger than in the open and closed configurations. An actuator (104) is operatively coupled to the fiber handling element (116) for moving the latter between the open closed and tensing configurations.
