Push Gigabit Ethernet farther with a copper-to-fiber conversion point built for long-distance network extension. The ET91000SM10 converts 10/100/1000Base-T copper to 1000Base-LX fiber and supports single-mode LC cabling for runs up to 10 km. That makes it a practical fit when you need to bridge floors, connect separate facilities, or replace unreliable long copper spans with a more stable fiber path. This model is designed for straightforward deployment in environments where uptime and signal integrity matter. By moving traffic onto single-mode fiber, you gain the distance headroom needed for remote closets, campus links, and distributed infrastructure without changing the Ethernet service at either end. The converter’s TAA compliance also makes it suitable for public sector and regulated procurement workflows. For teams standardizing on fiber backbones, this unit fills a precise role: extend the network cleanly, preserve Gigabit performance, and avoid the cost of replacing active equipment just to reach the next segment. It is a focused solution for infrastructure teams that need dependable transport, not extra complexity.
