Push Ethernet farther without changing the network architecture. StarTech ET90110WDM2 converts and extends a 10/100 Mbps Ethernet connection over fiber for distances up to 20 km, making it a practical fit for remote buildings, industrial spaces, and campus links where copper cannot reach reliably. This media converter is designed for straightforward point-to-point extension of Fast Ethernet traffic while preserving the link between distant devices. It gives infrastructure teams a clean way to bridge long spans without introducing unnecessary complexity at the edge. For environments where uptime and distance matter more than port density, it provides a focused, purpose-built answer. Choose this model when you need a dedicated conversion path for legacy 10/100 Mbps equipment and a longer reach than standard copper can support. It helps maintain connectivity across separated network segments while keeping the deployment simple and predictable.
