Product information

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

Key specifications

  • Model: ET91000SM20 (StarTech.com)
  • Data rate: up to 2000 Mbit/s
  • Copper interface: 1 × 1000Base-T (RJ45)
  • Fiber interface: 1 × 1000Base-LX single-mode (LC, pre-installed SFP)
  • Maximum fiber distance: 20 km
  • Wavelength: 1310 nm
  • Enclosure: steel (metal)
  • Indicators: link and power LEDs
  • Colour: black

How to use

Connect the copper Ethernet device to the RJ45 port and insert the single-mode fiber cable into the LC port on the pre-installed SFP transceiver. Power the unit and verify link and power LEDs to confirm connectivity. If required, remove the SFP module and replace it with a compatible SFP to match different fiber types or distances. For rack installations, the module can be used standalone or installed into compatible StarTech.com enclosures or chassis (sold separately).

Usage recommendations

Use single-mode fiber cables rated for the intended distance and ensure proper cleaning of LC connectors before installation. Place the converter in a ventilated area and consider rackmount enclosures for multi-unit deployments to improve cable management and physical protection.
