A fiber fast connector, also known as a mechanical splice or cold connector, is a field-installable connector that terminates fiber optic cables without requiring a fusion splicer. Good connectors use tiny ceramic ferrules to precisely center each fiber core. The fiber connector types, sometimes referred to as terminations, link fiber optic cables together through terminals, switches, adapters, and patch panels, by bridging the gap between their. The fiber connector is called a fiber optic or optical fiber connector.
