Network Media Converter ROLINE 21.13.1174

The ROLINE 21.13.1174 network media converter provides a compact solution to bridge copper Ethernet and SFP-based fiber links. Designed for environments with limited space, it accepts a 1000Base-T RJ-45 input and converts traffic to an SFP fiber interface. The unit is compatible with common IEEE standards for Gigabit and Fast Ethernet, enabling integration into existing network infrastructures that follow 802.3, 802.3ab, 802.3u and 802.3z specifications.

Advantages

This media converter delivers reliable copper-to-fiber conversion in a small form factor, helping extend network reach and isolate segments over fiber while keeping footprint and cabling complexity low. Compliance with IEEE standards ensures predictable interoperability with switches, routers and SFP transceivers that adhere to the same protocols. Its single-port design simplifies deployment where only one link needs conversion, and the device’s compact dimensions make it suitable for installation in racks, cabinets or near endpoint devices.

Suitable for (tasks / use cases)

• Extending Gigabit Ethernet links from RJ-45 copper to fiber with SFP modules
• Connecting network equipment across longer distances where copper is impractical
• Isolating sensitive network segments by migrating parts of the infrastructure to fiber
• Space-constrained installations such as small racks, wall mounts or desktop set-ups

Key specifications

• Input interface: 1000Base-T (RJ-45) copper Ethernet port
• Output interface: SFP fiber optic connector (user-supplied SFP transceiver)
• Standards compliance: IEEE 802.3, 802.3ab, 802.3u, 802.3z
• Physical dimensions: approximately 75 mm (W) × 60 mm (D) × 23 mm (H)
• Port count: 1 copper Ethernet port and 1 SFP slot

How to use

Install an appropriate SFP transceiver into the device’s SFP slot and connect the fiber optic cable to the transceiver. Plug a standard RJ-45 cable from the 1000Base-T port to the copper Ethernet device or switch. Power the media converter according to the manufacturer’s power supply instructions and verify link/activity LEDs (if present) to confirm connectivity. Ensure the chosen SFP transceiver matches the fiber type and wavelength required by the remote endpoint.

Recommendations

Use compatible SFP modules and follow IEEE-standard cabling practices to ensure stable Gigabit performance. For best results, verify link negotiation settings on connected network devices and keep the converter in a well-ventilated location to avoid heat buildup. When deploying in critical or long-distance links, test end-to-end connectivity and throughput after installation.
