Overview
The RB-SERIAL is a professional-grade set of two fiber media converters designed to extend asynchronous serial interfaces over a single strand of fiber optic cabling. This set supports both RS-232 and RS-485/422 interfaces, allowing them to operate simultaneously and independently over either multi-mode or single-mode fiber.
Built for industrial durability, these converters feature a fan-less aluminum alloy housing and are designed to provide reliable data transmission in harsh environments. They are ideal for applications requiring long-distance serial communication while maintaining immunity to electromagnetic interference (EMI) and electrical surges.
