Product Description

RS485 Fiber Optic Transceiver, Serial Data Over Fiber Converter Extender, Transmit RS485 Signals Up to 20KM Over Single Mode Fiber, Plug and Play, EMI Immune for Security PTZ Access Control Building Automation

Product Description

The RS485 Fiber Optic Transceiver is a reliable serial data transmission solution designed to overcome the distance limitations and electromagnetic interference issues associated with traditional copper RS485 cabling. This high-performance converter transforms RS485 electrical signals into optical signals for transmission over fiber optic cables, enabling stable long-distance communication in various commercial and residential environments.
Utilizing advanced fiber optic technology, this transceiver provides complete immunity to electromagnetic interference (EMI), radio frequency interference (RFI), and ground loop problems commonly found in buildings with multiple electrical systems. It supports transmission distances up to 20 kilometers over single-mode fiber and up to 2 kilometers over multi-mode fiber, making it perfect for connecting devices across large buildings, campuses, or between separate facilities.
This device features fully transparent data transmission with automatic baud rate adaptation from 0 to 115.2kbps, ensuring seamless compatibility with all standard RS485 protocols including Modbus, BACnet, and more. No software configuration or manual baud rate setting is required - simply connect your devices and the transceiver will automatically detect and synchronize with your data speed.
Built with durable materials and reliable components, this transceiver features a compact metal enclosure with 300W surge protection and ±8kV electrostatic discharge (ESD) protection on the RS485 port. It supports wall-mount installation and operates reliably in standard indoor environments, making it suitable for a wide range of applications from security systems to building automation.
