These fiber optic connectors enable fast, fool-proof and easy termination of a fiber. Terminations can typically be made in 5 seconds, with no termination tools required. Insert the prepared fiber into the connector, slide the connector's switch-like activator toward the fiber to be terminated to bring about the splice/crimp, and slide the boot on the connector body. This fiber installation procedure is accomplished without using any specific or proprietary installation tools. The built-in activator tab performs the fiber splicing and crimping action in one simple motion, thus reducing the number of steps involved by 50 percent.
