Gigabit Copper-to-Fiber Media Converter

This media converter bridges a 1000Base-T copper link to single-mode LC fiber, extending the connection up to 20 km. It is designed for network engineers and installers who need to span buildings or campuses without deploying repeaters. The unit includes a pre-installed SFP transceiver and a universal power adapter for immediate deployment.

Rugged Metal Housing and LED Diagnostics

The converter is built in a rugged metal enclosure that sits on any flat surface or slides into an ETCHS2U chassis for rack mounting. Six status LEDs show power, remote power fault, link fault pass-through, link activity, copper link and copper duplex, giving instant visibility of both fiber and copper segments. Maximum power draw is 19.2 W from the supplied adapter.

Check Fiber Type and Chassis Compatibility

Verify that your existing cabling is single-mode fiber with LC connectors and that the 1310 nm wavelength matches the far-end equipment. If you plan to rack-mount multiple units, confirm you have an ETCHS2U chassis available; otherwise the converter operates standalone. Buyers who need multimode fiber or a different connector type cannot use this model.

Questions about this item

What standard does the 1310 nm single-mode LC interface support, and what distance does it cover?

The converter uses a 1310 nm single-mode LC SFP transceiver to extend a 1000 Mbps Gigabit Ethernet link up to 20 km (12.4 mi) over single-mode fiber.

What are the physical mounting options and dimensions for this unit?

The rugged metal housing measures 1.72 kg and operates standalone on a flat surface or can be installed in the ETCHS2U 2U chassis for rack mounting.

How do I power and connect the converter, and which LED confirms the fiber link?

Connect the included universal power adapter, link the RJ45 port to copper and the LC port to single-mode fiber; the LFP LED indicates a valid fiber connection.
