Product Features
Technical Overview
This media converter provides a straightforward two-port interface: one RJ-45 port for copper Ethernet (1000Base-T) and one LC duplex port for single-mode fiber (1000Base-LX). It operates at a wavelength of 1310 nm, which is standard for long-distance single-mode fiber applications. The converter supports full and half duplex operation, Jumbo Frames up to 9.6K, and is compliant with IEEE 802.3ab (1000Base-T) and IEEE 802.3z (1000Base-LX) standards, ensuring interoperability with existing Gigabit network equipment.
Power is supplied via an included universal AC adapter (compatible with NA, EU, UK, and AU outlets), which connects using a Type M plug. The converter's compact dimensions—0.90" height, 3.50" width, and 6.40" depth—allow for flexible placement on a desktop or mounting in a standard 19-inch rack using optional brackets. Its low power draw of 19.20 W contributes to energy-efficient operation in always-on network deployments.
Key Product Advantages
The ET91000SM10 media converter extends network reach far beyond the 100-meter limit of standard copper Ethernet, enabling cost-effective fiber connectivity without replacing entire network infrastructures. Its integrated SFP transceiver reduces deployment complexity and cost, while features like Link Fault Passthrough and Auto Laser Shutdown enhance network reliability and safety.

Deployment / Use Cases
This media converter is ideal for scenarios where extending Ethernet over fiber is necessary to overcome distance, interference, or security constraints. It seamlessly integrates into existing networks, providing a bridge between copper and fiber segments without requiring changes to end devices or network switches.
Common applications include connecting remote offices or data centers across a campus, linking security cameras or access control systems over long distances, integrating fiber backbones into copper-based LANs, and extending network connections in industrial environments where electrical noise is a concern. The rack-mountable design makes it suitable for installation in network closets, server racks, or telecom enclosures, while the standalone form factor allows for temporary or desktop deployments.
Campus Network Extension
Connect buildings across a university, corporate park, or hospital campus using existing single-mode fiber infrastructure, maintaining high-speed connectivity for VoIP, video surveillance, and data transfers.
Industrial Networking
Deploy in manufacturing plants or outdoor installations where fiber's immunity to electromagnetic interference ensures reliable network performance in electrically noisy environments.
Physical Profile
The converter features a compact, low-profile design with a height of 0.90 inches (22.86 mm), width of 3.50 inches (88.90 mm), and depth of 6.40 inches (162.56 mm), weighing approximately 14.50 ounces (411.07 g). Its steel housing provides durability and shielding, while the form factor supports both desktop use and rack mounting with optional accessories. The small footprint allows for dense installations in rack environments or discreet placement in network cabinets.
