Advantech EKI-2741FI-BE, 1000Mbps, SFP Hardened Media Converter

When your network needs to stretch beyond copper limits, the signal can drop, cause errors, and slow down critical applications. The EKI-2741FI-BE Giga Ethernet to SFP Fiber Converter W/T bridges that gap by turning a standard RJ-45 Ethernet link into a reliable fiber connection. It lets you extend gigabit speeds up to 100 m over copper and far farther over fiber, keeping your data flow smooth and secure.

EKI-2741FI-BE solves long-distance Ethernet challenges

Many factories, data centers, and remote sites struggle with limited cable runs and interference on copper lines. This problem can lead to downtime and costly troubleshooting. The EKI-2741FI-BE provides a clear solution by converting 10/100/1000Base-T Ethernet to 1000Base-SX/LX fiber, eliminating signal loss and electromagnetic noise. It follows IEEE 802.3 standards, ensuring compatibility with existing equipment while delivering up to 1000 Mbps throughput.

Usages

The converter fits into any environment where Ethernet must travel long distances or through harsh conditions.

• Connect a control room to remote sensors on a production floor.
• Link two buildings in a campus without laying new copper cable.
• Upgrade legacy copper networks to fiber in a data center rack.
• Provide a resilient link for outdoor surveillance cameras.

Benefits

You gain a stable, high-speed link that works even in electrically noisy areas, so your applications run without interruption. The built-in auto-negotiation means the device matches the best speed and duplex mode automatically, saving you time on configuration. Redundant dual power inputs (12 ~ 48 VDC) keep the connection alive if one power source fails, increasing reliability for mission-critical systems. The compact DIN-rail or wall-mount design lets you install it in tight spaces, freeing up rack space for other gear. Finally, the Link Fault Pass-through feature alerts you instantly when the fiber link drops, helping you prevent hidden network failures.
