Product Overview
Used B&B Electronics FOSTCDRI-ST Serial 232/422/485 to Single-Mode Fiber Converter
The B&B Electronics (Advantech) FOSTCDRI-ST is an industrial-grade fiber converter designed to bridge standard serial communications (RS-232, RS-422, or RS-485) to single-mode fiber. Built for harsh environments and long-distance data transmission, this converter offers stable, isolated performance for automation, SCADA, and remote telemetry systems.
Used, clean, and fully functional with power verified. This unit represents B&B’s longstanding reliability in industrial communication hardware—ready to link legacy serial systems to modern fiber networks with minimal noise or interference.
Product Condition
Used and in good condition. Clean exterior, all ports intact, and unit powers up normally. Minor handling wear consistent with prior service. No damage to connectors or housing.
Product Overview
B&B Electronics, now part of Advantech, has been a trusted name in data connectivity for decades. The FOSTCDRI-ST model supports RS-232, RS-422, and RS-485 serial standards and converts them to single-mode fiber transmission using ST-type connectors. With data rates up to 115.2 kbps and isolation up to 2 kV, it provides robust performance in industrial automation and control networks where electrical noise or long distances challenge copper-based communication.
