ET91000SM10 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 10 km (6.2 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 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 ET91000SM10 enclosure, plus its 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 10 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 ET91000SM10 is backed by a StarTech.com 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
