LevelOne RJ45 to SC BIDI Fast Ethernet Media Converter Set, Single-Mode Fiber, 20km

The LevelOne Media Converter Set RJ45 to SC BIDI FVT-2202 converts 10/100Base-TX copper Ethernet to single-mode fiber and back, enabling network extension over long distances. The set uses a bi-directional (BIDI) SC fiber interface that transmits separate wavelengths in opposite directions over a single optical fiber and supports a maximum single-mode range of up to 20 km. The compact black units comply with IEEE Fast Ethernet speeds (10/100 Mbit/s) and include LED indicators for power, link and activity.

Advantages

This media converter set supports 10/100Base-TX to fiber conversion with built-in Link Fault Pass-through (LFP) technology (LLCF/LLR) to propagate link status between copper and fiber sides. Dip switches allow basic configuration of operating modes. The BIDI SC interface reduces fiber cabling by using one single-mode fiber for both directions. The devices support low-latency transmission and accept extra-long Ethernet frames up to 1.6 KB.

Suitable for

• Extending LAN segments between buildings or across a campus up to 20 km
• Connecting legacy copper Ethernet equipment to a single-mode fiber backbone
• Point-to-point fiber links where single-fiber BIDI cabling is preferred

Key specifications

• Model: LevelOne FVT-2202 (RJ45 to SC BIDI)

How to use

Connect the RJ45 port to the copper Ethernet device or switch and connect the SC BIDI port to single-mode fiber using the SC connector. Ensure the paired converter at the remote end is configured for the complementary BIDI wavelengths. Power on both units and check LED indicators for power, link and activity. If link issues occur, enable or verify LFP behaviour via dip switches according to your network requirements.

Recommendations

For reliable operation, use ITU-T-compliant single-mode fiber and quality SC connectors; keep fiber ends clean and use compatible BIDI transceivers on both ends. Verify cable distance does not exceed 20 km and confirm dip switch settings and power supply (5 V) before deployment.
