Description
The Perle PSI-MOS-RS422/FO1300 E Serial to Fiber Converter (Part Number: 27085758) enables transparent conversion of RS422/485 4-wire signals to fiber optic connections, extending communication over long distances with high reliability. By leveraging optical fiber, it eliminates electromagnetic interference, increases signal integrity, and provides an economical solution to extend the reach of serial devices.
Supporting both multimode fiber up to 27 km (16.7 miles) and single-mode fiber up to 45 km (28 miles), this converter is ideal for mission-critical applications in industrial automation, utilities, and data communications. The SC duplex connector ensures secure and stable connections, making it a versatile choice for modern serial-to-fiber deployments.
