B&B Electronics BB-5740 RS-232 to Fiber Optic Serial Converter

The B&B Electronics BB-5740 is a RS-232 to fiber optic serial converter designed to extend serial data communications over fiber optic cable. By converting standard RS-232 signals to optical format, this device eliminates ground loop issues, provides immunity to electromagnetic interference (EMI), and enables long-distance serial communication well beyond the limitations of standard copper cabling.

Key Features:

• Converts RS-232 serial signals to fiber optic for noise-free data transmission
• Eliminates EMI and RFI interference common in industrial environments
• Provides electrical isolation between connected devices
• Supports extended transmission distances beyond standard RS-232 limits
• Compatible with standard RS-232 serial devices and equipment
• Compact, rugged design suitable for industrial and commercial applications

The BB-5740 is ideal for use in industrial automation, process control, data acquisition, and any application where serial data must travel over long distances or through electrically noisy environments. B&B Electronics (now part of Advantech) has a long-standing reputation for reliable serial communications and connectivity solutions.
