## Long description

The StarTech.com Gigabit Ethernet Copper-to-Fiber Media Converter (ET91000SM20) provides a cost-effective way to extend network links up to 20 km. It converts 1000Base-T copper Ethernet to 1000Base-LX single-mode fiber at 1310 nm and includes a pre-installed Gigabit SFP transceiver with LC connector. The converter is housed in a durable metal enclosure and offers LED indicators for link and power status.
Advantages
This media converter reduces electromagnetic interference compared with copper-only connections, enabling longer, more secure links between buildings or remote network points. Its metal (steel) enclosure improves durability in demanding environments such as warehouses or industrial sites. The pre-installed SFP module can be swapped to adapt to future infrastructure changes, and the unit supports diagnostic features like Link Fault Passthrough, Auto Laser Shutdown (ALS), and Auto-MDIX to simplify setup and troubleshooting.
Suitable for
Extending Ethernet links between buildings up to 20 km
Connecting copper-based network equipment to fiber switches with SFP ports
Industrial or warehouse network deployments requiring EMI resistance
Secure or government/education networks where reduced interference is needed
