Media converter ADVANTECH EKI-2541S-AE — Ethernet 10/100 Mbps to single-mode fiber, 1 fiber port

The ADVANTECH EKI-2541S-AE is a media converter designed to bridge 10/100 Mbps Ethernet copper networks and single-mode fiber links using one optical fiber port. Its compact form factor and industrial-grade design allow integration into LAN segments or point-to-point connections where extended reach and electrical isolation are required. The device supports standard Ethernet signaling on the RJ45 side while providing a single-mode fiber interface for long-distance transmission in network infrastructure and industrial environments.

Advantages

The media converter provides reliable conversion between copper and single-mode fiber without modifying existing Ethernet equipment, enabling longer link distances and immunity to electrical interference. Its small footprint facilitates installation in constrained spaces or on DIN rails when used with compatible mounting accessories. The device reduces the need for expensive rewiring and offers a straightforward solution for extending network reach and improving signal integrity over long distances.

Suitable for

• Extending Ethernet links between buildings or sites over long distances
• Connecting industrial equipment requiring electrical isolation from network switches
• Integrating legacy 10/100 Mbps devices into a fiber-based backbone
• Point-to-point fiber connections in surveillance, access control, or remote I/O systems

Key specifications

• Data rate: 10/100 Mbps Ethernet
• Fiber type: single-mode optical interface
• Ports: one RJ45 copper Ethernet port and one single-mode fiber port
• Transmission mode: media conversion between copper and optical link
• Typical use: long-distance Ethernet extension and electrical isolation
• Form factor: compact industrial enclosure suitable for rack, wall, or DIN-style mounting with appropriate accessories

How to use

Install the media converter near the existing copper Ethernet device or at the fiber link endpoint. Connect the RJ45 Ethernet cable to the copper port and terminate the single-mode fiber at the optical port using the appropriate fiber connector type. Ensure proper fiber polarity and secure connections. Provide power to the converter according to the manufacturer's power input specifications and confirm link LEDs or indicators show a stable connection. Configure network devices at each end of the link with compatible speed and duplex settings if required.

Recommendations

Place the media converter in a dry, ventilated location away from direct heat sources and strong electromagnetic interference. Use single-mode fiber patch cords and connectors rated for the deployment distance, and verify power supply compatibility before installation. For industrial installations, use recommended mounting accessories and observe grounding and surge protection practices suitable for the environment.
