Fiber Optic Connectors are accessories used to attach one fiber or cable to another, allowing light signals to travel between them. The 501457-4 is an external Dust Cap Connector for terminating SC/PC-type single-mode fiber patch cords. This connector type is used to connect tones of separate jackets, and is best suited for industrial control and laboratory applications.

Application Field

Multi-mode applications are one of the main uses of the 501457-4 dust cap connector. It is designed to terminate a single-mode fiber patch cord on a Standard Triple-Shield Cable (STC), but can also be used for connecting mode-conditioning cables, flat ribbon cable, shielded or un-shielded pair cables, military qualified cables, and armor-lined cables. This connector type is ideal for connecting network components within industrial facilities and control systems. It is also well suited for laboratory work, where reliability and re-usability are important.

Working Principle

The 501457-4 connector functions much like any other fiber optic connector. An inner core with a single fiber is placed in the connector by removing the dust cap. The core is then aligned flush with the guide marks imprinted on the connector, and the compressed base is attached and secured by tightening two screws. Once the core has been sealed in place, the connector is ready for use. Light signals are passed through the Core, allowing signals to be transferred between two cables or fibers.

The 501457-4 dust cap connector falls in the same Fiber Optic Connectors - Accessories class as most other connectors, including the SC, ST, and MU connectors. It is designed to provide secure transmission of signals between two ends and is designed to be re-usable. When used with the appropriate cable type, the 501457-4 dust cap connector offers reliable, repeatable, and secure connections that will last for years.
