A connector assembly for reversibly terminating a fiber optic cable comprising an optical fiber stub and an actuator illustratively configured for sliding along a path between a first position and a second position which illustratively serves to move one or more anvils thereby mechanically clamping the fiber optic cable proximate to the optical fiber stub. It is an optical fiber cable comprising a central reinforcing element, a plurality of optical fibers surrounding the central reinforcing element, the bare optical fibers being pressed in contact against the central reinforcing element in such a manner as to be mechanically coupled to the central reinforcing element. The sensing unit is coupled to the alert unit for sensing the external signal so as to enable the alert unit. The monitor device comprises a monitor portion which includes a display device for displaying an image and a sound device for outputting sound, a fixing portion for connecting and fixing the monitor portion to the casing, a signal input terminal for receiving a signal from the signal output terminal connected thereto when the monitor device is connected to the casing. This notifier contains the multicast address and port to where the. Those hot keys are pre-defined by functions for either the left or the right hand user to operate without changing another type of mouse.
