Media converter MCV-1020-SF/SM-5-R Single-fiber 10/100 Mbps, 20 km

The MCV-1020-SF/SM-5-R Single-fiber 10/100 Mbps, 20 km media converter provides conversion between 10/100 Mbps copper Ethernet (RJ45) and single-mode fiber over a single fiber strand. Designed for extending network links up to 20 km, it enables integration of Ethernet devices into fiber infrastructure while preserving full-duplex and half-duplex modes. The compact unit supports desktop or rack mounting and is intended for use where a single-fiber solution is preferred to minimize cabling and simplify long-distance connections.

Advantages

This media converter allows seamless conversion between twisted-pair copper and single-mode fiber without altering network configuration. It supports 10/100 Mbps speeds and common Ethernet operation modes, delivering stable data transmission over long distances. The single-fiber design reduces fiber cabling needs and can lower installation complexity and cost in point-to-point links. Its compact footprint supports flexible placement in small racks or on a desktop.

Suitable for

• Extending Ethernet links between buildings or across a campus up to 20 km
• Connecting switches, routers or IP devices to a single-mode fiber backbone
• Integrating legacy 10/100 Mbps equipment into fiber-based networks
• Point-to-point links where minimizing fiber strands is required

Key specifications

• Data rates: 10/100 Mbps Ethernet
• Fiber type: single-mode, single-fiber operation
• Maximum link distance: up to 20 km (typical single-mode reach)
• Copper interface: RJ45 10/100Base-TX
• Duplex modes: full-duplex and half-duplex support
• Mounting options: desktop or rack installation
• Compact form factor suitable for space-constrained installations

How to use

Install the converter in a suitable indoor location with adequate ventilation and within reach of power and network cabling. Connect the RJ45 copper Ethernet cable from the switch, router or device to the RJ45 port on the unit. Terminate the single-mode fiber to the single-fiber transceiver connector according to the manufacturer's fiber polarity and connector type requirements. Power on the unit and verify link/activity LEDs for proper operation. Configure connected Ethernet devices to the appropriate speed and duplex if auto-negotiation is not used.

Usage recommendations

For reliable performance, use single-mode fiber and connectors matched to the converter's transceiver specifications and maintain clean fiber end-faces. Ensure proper grounding for nearby network equipment, avoid sharp bends in fiber cabling, and verify link stability after installation. If integrating with managed switches, confirm port settings (speed/duplex) to prevent mismatches.
