Foxboro P0972UN Fiber Optic Cable I/A Series

Product Description

The Foxboro P0972UN fiber optic jumper is a short-length, single-mode patch cable engineered for reliable optical communication within Foxboro I/A Series control systems. Designed for cabinet-level interconnections, it enables stable, high-speed data transfer between controllers, communication modules, and network interface units without susceptibility to electromagnetic interference.

Its LC duplex connectors ensure precise alignment and low insertion loss, making it suitable for deterministic industrial networks where signal integrity is critical. The compact 0.5-meter length is optimized for internal panel routing, minimizing excess slack and improving cable management in dense control enclosures.

FAQ

Q: Is this cable suitable for long-distance transmission?
A: No. The 0.5 m length is intended for short interconnections inside control panels. For longer distances, extended single-mode fiber assemblies are recommended.

Q: Can it be used outside Foxboro systems?
A: Yes. As a standard LC-LC single-mode cable, it is compatible with any equipment using LC interfaces, though it is specifically qualified for Foxboro I/A Series environments.

Q: What is the advantage of single-mode fiber in this application?
A: Single-mode fiber provides lower attenuation and higher bandwidth compared to multimode, ensuring reliable communication even in electrically noisy industrial settings.
