ET91000SM20 Fibre Media Converter

This Gigabit Ethernet to fibre 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.).

Fibre 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-fibre converter supports standalone operation, or alternatively it can be installed into the 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 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 fibre 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 fibre 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 Pass-through, 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 fibre-based network switches feature SFP ports more often than RJ45 ports, you might need a converter to bridge your copper and fibre networks together.

The ET91000SM20 is backed by a 2-year warranty, and free lifetime technical support.

Features & Benefits

• Supports Link Fault Pass-through (LFP), Auto Laser Shutdown (ALS), and Auto MDIX
• Up to 9.6K Jumbo Frame support
• Supports full or half-duplex operation, as well as auto negotiation or forced mode
• Media converter's card module is compatible with enclosures from other ET91000 series media converters (sold separately)
• Compatible with Gigabit (1000Mbps) copper (IEEE 802.3ab, 1000BASE-T) and fibre (IEEE 802.3z, 1000BASE-LX) protocols
• Fast, hassle-free setup
• Rugged steel enclosure
• Flexible network integration, with support for standalone operation, or installation into the Rackmount Chassis (ETCHS2U - sold separately)
• Converts copper to fibre and extends your network up to 20 km (12.4 mi.) using single-mode LC fibre-optic cable (1310 nm)
• Removable SFP module (LC fibre connector) can be replaced should your network infrastructure change


• Can be installed into the 20U rackmount chassis (ETCHS2U - sold separately)
• Use fibre 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
