Foxboro P0972ZQ Fiber Optic Cable

Product Description

The Foxboro P0972ZQ is an industrial-grade single-mode fiber optic jumper developed for dependable optical communication in Foxboro I/A Series control architectures. It is intended for use in environments where electrical interference, safety requirements, and long-term reliability are key constraints.

This cable integrates precision-polished connectors with a low-loss fiber core to maintain signal integrity across control networks. The LSZH outer sheath reduces smoke and toxic emissions in the event of fire, making it suitable for enclosed cabinets and safety-critical installations. Multiple connector formats are supported, with SC-SC as the standard configuration and LC-LC variants available for high-density interfaces.

FAQ

Q: What is the difference between SC and LC connector versions?
A: SC connectors are larger and commonly used in standard panel interfaces, while LC connectors are compact and suited for high-density modules. The choice depends on the equipment interface.

Q: Why use LSZH cable in industrial cabinets?
A: LSZH materials reduce smoke density and eliminate halogen emissions during combustion, improving safety for personnel and sensitive equipment.

Q: Is this cable suitable for long-distance communication?
A: Yes. As a single-mode fiber assembly, it supports long-distance transmission, though actual range depends on the optical equipment used.
