Description
The Perle PSI-MOS-RS485W2/FO1300 E Serial to Fiber Converter (SKU: 27085628) provides a cost-effective and reliable way to extend the distance of serial communications over fiber optic cable. This industrial-grade media converter seamlessly connects RS232, RS422, and RS485 serial devices to duplex fiber at 1300nm (SC connector).
Offering both multimode (up to 27 km / 16.7 miles) and single-mode (up to 45 km / 28 miles) support, this converter is ideal for applications requiring noise immunity, signal integrity, and long-distance connectivity. Designed with rugged components, it ensures reliable performance in demanding environments where conventional copper cabling cannot meet distance or EMI requirements.
