B+B SmartWorx Triple Isolated RS-232/422/485 To Single-Mode Fiber SC Converter

The B+B SmartWorx Triple Isolated RS-232/422/485 To Single-Mode Fiber SC Converter is engineered to deliver dependable, long-distance serial communications over fiber. Designed for demanding industrial environments, this converter converts asynchronous serial data into a fiber signal, enabling two devices to communicate across miles with robust protection against electrical interference. With triple isolation and compatibility across RS-232, RS-422, and RS-485 interfaces, it ensures data integrity, minimizes downtime, and protects critical equipment from ground loops, surges, and EMI/RFI. When paired with a matching transmitter and receiver, these units form a transparent, high-performance serial link suitable for automation, SCADA, instrumentation, and remote monitoring applications.

• Triple-isolated protection delivers galvanic isolation between the serial interfaces and the fiber link, dramatically reducing the risk of ground loops, transients, and voltage differences that can cause data corruption or equipment damage in harsh environments.
• Broad serial interface support accommodates RS-232, RS-422, and RS-485 signaling with flexible duplex options, enabling half- or full-duplex operation over two single-mode fibers for reliable, long-range communication across diverse industrial networks.
• Long-distance single-mode fiber connectivity extends reliable communication up to 9 miles (14.5 km) over standard single-mode fiber with an SC-style connector, making it ideal for remote installations, distributed control systems, and factory floor networks with remote equipment.
• EMI/RFI immunity and high noise tolerance are inherent to fiber-optic links, ensuring clean data transmission in environments with strong electromagnetic interference, electrical noise, or hazardous industrial conditions.
• Plug-and-play integration with clear diagnostics features a compact, robust design, straightforward installation, and LED indicators that simplify monitoring of link status, activity, and power, minimizing downtime during deployment and maintenance.
