Product Features
Technical Overview
This media converter operates on 850 nm wavelength multi-mode fiber, supporting standard 50/125 µm and 62.5/125 µm core/cladding specifications. It achieves a maximum transmission distance of 4.20 km (2.61 miles), effectively overcoming the distance constraints typical of direct RS-485 connections. The device features one ST duplex optical port, ensuring proper transmit and receive channel separation for full-duplex communication.
The converter's electrical interface is specifically tailored for RS-485 (2-wire) signals, providing galvanic isolation through the fiber optic medium to eliminate ground loops and reduce susceptibility to electromagnetic interference. This isolation is crucial in electrically noisy environments common in industrial settings.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), DVI, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
The primary advantage of this converter is its ability to extend RS-485 networks far beyond their typical range while maintaining signal integrity. By converting to fiber optic transmission, it eliminates common issues associated with long copper runs, such as signal attenuation, data errors, and vulnerability to electrical noise.

Supports links up to 4.20 km, providing a reliable connection for remote devices where copper cabling would fail or require repeaters.
- Eliminates signal degradation over long distances
- Reduces data errors in noisy environments
- Provides consistent performance across the entire link
Industrial-Grade Design
Built for harsh environments with a rail-mountable form factor and compliance with major environmental standards.
- Rail-mountable for easy integration into control cabinets
- RoHS, REACH, and China RoHS compliant
- Suitable for 24/7 operation in industrial settings
Deployment / Use Cases
This converter is ideal for scenarios where RS-485 devices need to communicate over extended distances or across electrically isolated segments. Its fiber optic conversion makes it suitable for applications requiring noise immunity and long-range connectivity.
Common deployment environments include industrial automation floors, where it connects PLCs to remote I/O modules or sensors; building management systems, linking controllers across large facilities; and transportation infrastructure, such as connecting signal controls along railways or highways.
Industrial Automation
Connect PLCs, motor drives, and sensors across manufacturing plants without signal loss or interference from heavy machinery.
Building Management
Extend HVAC, lighting, and security system controls over fiber between different wings or floors of large commercial buildings.
Physical Profile
