Network Media Converter ROLINE 21.13.1138

The ROLINE 21.13.1138 is a compact multi-mode network media converter designed to bridge copper and fiber segments in Ethernet networks. Supporting up to 100 Mbit/s data transfer and equipped with an SFP fiber connector, it enables extension of wired connections over longer distances while maintaining compatibility with standard network equipment. The device is lightweight and housed in a black enclosure, suitable for installation in constrained spaces where simple media conversion is required.

Advantages

This media converter provides a straightforward solution for converting between copper and multi-mode fiber links at Fast Ethernet speeds. Its SFP interface allows flexible selection of fiber transceivers to match network type and wavelength requirements. The device's compact size and low weight make it easy to install in racks, wall mounts, or non-rack locations, and its support for distances up to 2000 m enables reliable link extension for building-to-building or long-run internal connections.

Key specifications

• Data rate: up to 100 Mbit/s
• Fiber type: multi-mode support (SFP interface)
• Maximum wired transfer distance: up to 2000 m (depending on fiber and transceiver)
• Connectivity: SFP fiber connector and copper Ethernet interface
• Colour: black
• Weight: approximately 200 g

How to use

Install a compatible SFP transceiver into the SFP slot, then connect the fiber cable to the transceiver. Connect the copper Ethernet port to a switch, router, or endpoint device using a standard Ethernet cable. Power the converter according to the supplied power instructions and verify link/activity LEDs (if present) to confirm connectivity. Ensure that transceiver type and fiber specifications match at both ends of the link to achieve the stated maximum distance and reliable operation.

Recommendations

Place the converter in a ventilated location away from direct heat sources and moisture. Use multi-mode fiber and SFP transceivers that match each other and the network's optical budget. For runs approaching the maximum distance, verify fiber condition and perform testing after installation to confirm signal integrity and throughput.
