Overview

The Patton FOI-4972-ST is an analog-to-fiber isolator designed to extend and isolate Plain Old Telephone Service (POTS) lines over multimode ST fiber optics. This device supports V.90 fax/modem interfaces, making it ideal for legacy telecom systems, dial-up modems, and secure telephone units (STU/STE) requiring fiber-optic isolation. The FOI-4972-ST is housed in a rugged military-style metal enclosure, ensuring durability in industrial or mission-critical environments. Unlike standard copper-based isolators, this unit converts analog signals to fiber, eliminating ground loops, EMI, and lightning-induced damage while maintaining signal integrity over long distances. The device is compatible with Patton’s fiber-optic modem interfaces and supports multimode ST optics for reliable connectivity. Power options are sold separately, allowing flexibility in power sourcing. Made in the USA, the FOI-4972-ST is a trusted solution for organizations requiring secure, interference-free analog signal transmission over fiber.
