This Crimp-Lock Connector is ideal for emergency restoration work or quick fiber connections made at the desk. For a sure connection, the fiber passes through the back end of the connector, through the conformable metal element, and beyond the end of the activation cap. Pressing the activation cap locking arm closes the metal element securely around the fiber. It's that simple. Crimp-Lock Connectors help eliminate possible points of failure because there is no fiber splice or second joint inside the connector, and there is no added attenuation at the connection. Inside the connector, fiber movement is prevented two ways: The malleable metal element is designed to grip the fiber, and the plastic buffer retention insert grips the buffer without crushing it when the crimp ring is crimped.
