Media converter LEVELONE FVT-2201 10/100TX to 100FX SC single-mode 20 km

The LEVELONE FVT-2201 media converter converts 10/100Base-TX copper Ethernet to 100Base-FX fiber using an SC connector for single-mode fiber up to 20 km. It supports standard 10/100 Mbps auto-negotiation and provides a compact solution to extend network links between switches, routers or workstations over longer distances. The device is intended to maintain stable signal transmission and reduce electromagnetic interference when replacing or extending copper links with fiber.

Advantages

The converter offers transparent media conversion between copper and single-mode fiber while preserving Ethernet frames and auto-negotiation features. Its single-fiber link capability for distances up to 20 km enables long-distance connections without intermediate repeaters. The compact form factor simplifies installation in constrained spaces and the fiber interface improves immunity to electrical noise and ground loop issues compared with copper cabling.

Suitable for

• Extending Ethernet links between buildings or floors up to 20 km
• Connecting switches and routers across campus or metropolitan networks
• Linking industrial or security equipment where electrical isolation is required
• Replacing problematic copper runs affected by interference or grounding issues

Key specifications

• Data rates: 10/100 Mbps auto-negotiation on copper, 100 Mbps on fiber
• Copper interface: 10/100Base-TX RJ-45
• Fiber interface: 100Base-FX SC connector, single-mode
• Maximum link distance: up to 20 km on single-mode fiber
• Media conversion: transparent layer 1 conversion supporting standard Ethernet frames
• Form factor: compact standalone unit suitable for desktop or rack mounting with appropriate accessories

How to use

Install the media converter near the copper-side device and connect the RJ-45 port to a switch, router or workstation using standard Cat5e/Cat6 cable. Terminate the fiber link with SC single-mode connectors and plug into the fiber port on the converter. Power the unit according to the supplied power adapter or local power source and verify link activity LEDs to ensure proper connection. The converter operates transparently without additional configuration; ensure both ends of the fiber link are using compatible speed and duplex settings where applicable.

Usage recommendations

Use quality single-mode fiber and proper SC connectors for distances approaching the maximum 20 km to maintain signal integrity. Verify fiber continuity and test link performance after installation. For installations in harsh environments, ensure the converter is placed in a protected enclosure and follow grounding and environmental guidelines for network equipment.
