Gigabit Ethernet Copper-to-Fiber Media Converter - SM LC - 20 km
StarTech ID: ET91000SM20
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 copperbased 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.
Applications
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
