Gigabit Ethernet Copper-to-Fiber Media Converter - SM LC - 20 km
Convert and extend a Gigabit Ethernet connection up to 20 km (12.4 mi) using single-mode LC fiber cable
Product ID: ET91000SM20
- Flexible network integration, with support for standalone operation, or installation into the StarTech.com Rackmount Chassis (ETCHS2U - sold separately)
- Converts copper to fiber and extends your network up to 20 km (12.4 mi.) using single-mode LC fiber-optic cable (1310 nm)
- Removable SFP module (LC fiber connector) can be replaced should your network infrastructure change
This Gigabit Ethernet to fiber media converter is a cost-effective way to extend your network, or extend the distance between two devices by up to 20 km (12.4 mi.).
Fiber network connections provide greater distance and security, with less electromagnetic interference (EMI) than typical RJ45 copper-based networks, making it perfect for IT professionals and secure setups in government, business, or educational applications.
Flexible integration into mixed network environments
This versatile copper-to-fiber converter supports standalone operation, or alternatively it can be installed into the StarTech.com Rackmount Chassis (ETCHS2U - sold separately), giving you more options for integration into your existing network. The card module can also be inserted back into the ET91000SM20 enclosure, plus it’s compatible with enclosures from other StarTech.com ET91000 series media converters (sold separately).
The converter features a pre-installed Gigabit SFP transceiver with LC connectors. Should your network infrastructure change in the future, you can easily swap and replace the module to adapt the media converter to your new network requirements.
With flexible integration and connectivity up to 20 km away, you can provide network access to remote areas in other buildings, or in areas where Wi-Fi® is unreliable or unavailable.
Rugged and reliable
This heavy-duty fiber media converter is designed for maximum reliability. It features a metal (steel) enclosure, so it can withstand the demands of harsh environments such as factories or warehouses.
Plus, by relying on this more durable fiber media converter, you can reduce the strain on your existing copper-based network equipment and potentially extend the life of those devices, which helps save future expenses.
Diagnose and correct issues easily
This high-performance media converter supports a range of network setup and diagnostic protocols (for example, Link Fault Passthrough, Auto Laser Shutdown (ALS), and Auto MDIX, so you can set up and troubleshoot your network easily.
Prepare your network for the future
If your existing network consists of RJ45 copper-based devices and cables, you might not be ready for future network expansion. Because the newest fiber-based network switches feature SFP ports more often than RJ45 ports, you might need a converter to bridge your copper and fiber networks together.
The ET91000SM20 is backed by a StarTech.com 2-year warranty, and free lifetime technical support.
Can be installed into the StarTech.com 20U rackmount chassis (ETCHS2U - sold separately)
Use fiber optic cable to connect to your network from remote areas or separate buildings, at greater distances than copper (RJ45) cable allows
Perfect for secure connections required by government agencies where EMI isn’t acceptable
Easily expand the number of ports on your existing network now, or in the future — perfect for small and medium businesses

Frequently Asked Questions
Before You Buy
Different optical cables are needed for different applications. Before you select a cable to interconnect fiber devices, make sure that the following things match:
Mode: Single Mode or Multi Mode.
Wavelength: For example, 850 nm, 1310 nm, or 1550 nm.
Note: The above properties cannot be converted or changed by a cable.
When you select a cable, make sure that the cable ends (for example, LC, SC, ST, or MT) match the fiber media devices.
Simplex and duplex ends are available for most connector types. Simplex cables have the connectors separate, where duplex cables have the transmit (TX) and receive (RX) connectors joined together. StarTech.com fiber media devices are compatible with simplex and duplex connectors.
It does not matter which diameter or OM classification the cable uses, as long as it meets the mode requirement.
Fiber media converters can be used to convert a standard Ethernet connection to a standard fiber connection, or can be used to extend a copper Ethernet network. When you use fiber media converters to extend a copper Ethernet network, make sure that the same fiber standards are being used on either end of the fiber network.
Note: Terms like 1000BASE-LX, 100BASE, 1000BASE, and 10GBASE refer to how fast the data can transfer, with 100BASE being 100Mb/s, 1000BASE being 1000Mb/s or 1GB/s, and 10GBASE being 10Gb/s. FX, SX, LX, and SR refer to different fiber standards and use different wavelengths (among other things).
Fiber media converters come in different types for different applications. You need to consider the specifications for both network devices before you can select the correct fiber media converters.
A fiber media converter can be used to simply convert fiber to copper (for example, 100BASE-FX to 100BASE-TX), convert copper to fiber, or it can be used to extend a copper network over fiber optic cabling. If you use an application that uses fiber media converters, the copper and fiber industry standards must match.
The following is an example of a working fiber to copper setup:
- A network switch that has an LC fiber output using 1000BASE-LX is connected to an LC fiber cable that patches into the ET1000S40LC2, which is compatible with 1000BASE-LX/SX. The connected copper device is 1000BASE-T.
If the copper device in the above setup is 10/100 (100BASE-T), no copper link would be detected.
Note: Some media converters do not auto-negotiate copper or fiber standards, which limits the device to 10/100 or gigabit operation. For more information, check the specifications of the media converter.
When you use the fiber media converter in a network extender setup, it works best if you use the same media converter on either end. As long as the fiber standards match, you can use different connectors and the fiber network will be created between the units.
The following are some examples of available fiber connector types:
- Open SFP
The Open SFP units (referred to as Open on the Fiber Media Converter Drilldown) can use any mini-GBIC or SFP compatible fiber transceiver. The ET LC fiber media converters include LC SFPs, which makes the unit an open SFP, if required.
When you troubleshoot issues with a fiber media converter, there are some quick tests that you can complete to rule out potential problems. To identify what the source of the issue is, observe the power LED, LAN LEDs, and fiber link LED on the units.
If the power LED is not illuminated for the transmitter or the receiver, complete the following:
Make sure that you are using the provided power adapter(s).
Make sure that the adapter is plugged into a compatible wall outlet.
Make sure that the adapter is plugged into both the transmitter and receiver.
If another LED is not operating as expected, make sure that the components in your setup are working correctly. To test your setup components, try the following:
Use the cables, fiber media converter, and network devices (including SFPs, if applicable) in another setup to see if the problem is with the components or the setup.
Use different cables, fiber media converter, and network devices (including SFPs, if applicable) in your setup to see if the problem persists. Ideally, you should test components that you know work in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
Make sure that the DIP switches are set to the following:
DIP switches should be identical on both local and remote units. By default, DIP switches are set to Off (the switch is pointing up).
For more information about the advanced configuration options, refer to the manual for your product.
If you cannot establish a network connection between your local and remote units, you need to do the following to make sure that the issue is not related to the network configuration:
Use two computer systems directly connected to the fiber media converter LAN ports.
Open a command prompt on Computer 1 and ping Computer 2.
If the issue is not related to the network configuration, you should receive a response from Computer 2.
For more information on how to ping another network device, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=networking#ping-test-windows-mac-os.
