Industrial Mini Converter ROLINE 10/100TX - 100FX (SC)

The ROLINE Industrial Mini Converter 10/100TX - 100FX (SC) provides copper-to-fiber media conversion for 10/100 Mbps Ethernet links. It combines a 10/100TX copper port with a 100FX single-mode SC fiber port to enable reliable data transmission over fiber optics in industrial environments. The unit is compact, supports DIN-rail mounting and a wide operating temperature range, and is suitable for extending networks where fiber connectivity and industrial-grade performance are required.

Advantages

The converter supports full wire-speed conversion for 10/100 Mbps connections and offers auto-negotiation or forced speed on the copper port with Auto-MDI/MDIX for plug-and-play operation. It passes link faults across media (Link Fault Pass Through) and provides Far End Fault detection on the fiber port. The device transparently handles 802.1Q VLAN tagged packets, delivers low latency for 100Mbit/s conversions, and features low power consumption. Its industrial-rated emission and immunity performance, compact dimensions and multiple power input options make it suitable for deployment in cabinets and chassis.

Suitable for

• Extending Ethernet networks from copper to single-mode fiber over short or long distances
• Industrial automation and control systems requiring robust media conversion
• Installations with limited space where a compact DIN-rail mountable converter is needed

How to use

Mount the converter on a DIN rail or install it inside a suitable enclosure. Connect the copper Ethernet cable to the 10/100TX port and the single-mode SC fiber cable to the 100FX port. Apply appropriate DC power via the terminal block or DC power jack within the specified input range (+4.5 to +50 VDC). The device will automatically negotiate speed or operate in forced mode as configured; Auto-MDI/MDIX removes the need for crossover cables. Verify link status and VLAN traffic transparency during initial setup.

Usage recommendations

Use a recommended ROLINE DC power supply (model 21.13.1226 or 21.13.1228) for reliable operation. Ensure fiber connectors are clean and properly seated, and observe the specified operating temperature range. For installations in electrically noisy environments, follow grounding and wiring best practices to maintain industrial-rated emission and immunity performance.
