LevelOne RJ45 to SC Fast Ethernet Industrial Media Converter, Multi-Mode Fiber, 2km, -40°C to 75°C

The LevelOne IEC-4001 is an industrial Fast Ethernet media converter that converts 10/100Base-TX (RJ45) to 100Base-FX (SC) over multimode fiber up to 2 km. Built in a compact rugged aluminium housing, it supports DIN-rail or panel mounting and provides visible LED indicators for link, activity and power status. The converter supports wide input voltages and extended operating temperatures for deployment in industrial environments.

Advantages

The IEC-4001 combines a small, durable aluminium case with effective heat dissipation and surge/ESD protection to ensure reliability in electrically noisy environments. It supports Link Fault Pass Through (LFP) to notify remote devices of link changes, can operate as a pure converter or in switch mode, and accepts a wide input voltage range with polarity protection. The unit’s low power consumption and LED status indicators simplify installation and monitoring.

Suitable for

• Extending Fast Ethernet networks over multimode fiber up to 2 km
• Industrial environments requiring DIN-rail or panel mounting

How to use

Mount the IEC-4001 on a DIN-rail or attach it to a panel or wall using the provided fittings. Connect the copper Ethernet device to the RJ45 port and connect the SC multimode fiber to the fiber port, ensuring correct polarity and secure connectors. Apply a compatible power source within the specified voltage range and check the LEDs for power and link/activity status. If Link Fault Pass Through is required, enable/configure it according to system design and verify remote link monitoring.

Recommendations

Install the converter within the rated ambient temperature range and protect fiber connectors from contamination; use correct multimode fiber and SC connectors for reliable links. For installations exposed to strong electrical disturbances, ensure proper grounding and follow surge protection best practices.
