Mini Fast Ethernet Media Converter 10/100Base-TX to 100Base-FX

Extend your Ethernet beyond the limits of copper with a compact, reliable bridge between 10/100Base-TX and 100Base-FX networks. The Mini Fast Ethernet Media Converter is designed to convert a copper Ethernet segment to a fiber optic link, delivering uninterrupted connectivity, enhanced distance, and improved immunity to electrical interference. This small, fanless device is ideal for desktop, wall-mount, or cabinet installations and is perfectly suited for campuses, office buildings, data centers, or any environment where you need to span networks without a full switch upgrade. With its ST multimode fiber interface and a practical 2 km link capability, this media converter enables seamless integration of legacy Ethernet segments into modern fiber backbones, delivering a robust, cost-effective solution for network scalability.

• Compact, plug-and-play bridge between copper and fiber networks: 10/100Base-TX to 100Base-FX, enabling quick network upgrades without replacing existing switches.
• Copper interface supports 10/100 Mbps Ethernet with auto-negotiation and auto MDI/MDI-X, ensuring seamless compatibility with a wide range of switches, routers, and NICs.
• Fiber interface is 100Base-FX with ST multimode (MMF) connectivity for reliable, high-performance links over longer distances, up to 2 kilometers.
• Rugged yet compact design with a quiet, fanless operation that fits neatly on a desk, in a rack, or mounted to a wall for space-saving deployment.
• Transparent to higher-layer protocols and Ethernet frames, enabling straightforward integration with existing LAN infrastructure and minimizing downtime during installation.

how to install Mini Fast Ethernet Media Converter 10/100Base-TX to 100Base-FX

• Power down the devices you will connect to the media converter to avoid any electrical issues during setup.
• Connect the copper side to your existing network switch or router using a standard Ethernet cable (RJ45, 10/100 Mbps).
• Attach the fiber optic cable to the ST multimode connector on the fiber port, ensuring the other end is connected to your fiber-switched network or fiber optic device up to 2 km away.
• Apply power to the media converter using an appropriate external DC power supply (not included) and verify that the Power LED is illuminated.
• Check the copper and fiber Link/Act LEDs to confirm a healthy connection on both sides. If Link is shown but there is no activity, test data transmission to confirm end-to-end connectivity.

Frequently asked questions

• What is the purpose of this device? It serves as a bridge between copper Ethernet networks (10/100 Mbps) and fiber networks (100 Mbps), allowing you to extend your LAN over longer distances without replacing existing switches.
• What type of fiber cable does it use? It uses multimode fiber with an ST connector for the 100Base-FX interface, suitable for indoor campus and office deployments up to 2 km.
• Do I need to configure the converter? No configuration is typically required. It is designed to be plug-and-play; simply connect the copper side to your switch and the fiber side to your fiber link.
• What about compatibility with existing equipment? It is designed to be compatible with standard Ethernet devices that support 10/100 Mbps Ethernet and 100 Mbps fiber, functioning transparently at the Ethernet layer.
• Are there any special considerations for installation? Ensure the fiber path is clean and clear, use proper fiber connectors, and verify LED indicators after powering on to confirm a healthy link on both sides.
