StarTech.com 10/100 Multi Mode Fiber Copper Fast Ethernet Media Converter ST 2 km

The StarTech.com 10/100 Multi Mode Fiber Copper Fast Ethernet Media Converter ST 2 km is a reliable, plug‑and‑play solution for extending your network beyond the reach of copper cabling. Designed for mixed environments—from busy corporate offices to home office setups—the converter seamlessly bridges 10/100 Mbps Ethernet over multimode fiber, enabling long‑distance connections without sacrificing performance. Built to endure the rigors of everyday networking, this sturdy device leverages a compact metal housing and a straightforward, driver‑free installation that fits neatly into any network rack or desktop setup. Whether you’re connecting distant buildings, extending a campus backbone, or linking security cameras to the main network, this StarTech media converter delivers consistent data integrity and stable operation over MMF links up to 2 kilometers.

• Seamless copper-to-fiber conversion with auto‑negotiation: The device automatically detects 10 or 100 Mbps Ethernet speeds and negotiates the best link parameters with your connected equipment, ensuring compatibility with legacy NICs, switches, or routers without manual configuration. This makes integration smooth in mixed environments where older hardware coexists with fiber backbones.
• Long‑haul multimode fiber support up to 2 km: Designed for campus deployments, building-to-building links, and remote office connectivity, this media converter leverages multimode fiber (MMF) to carry Fast Ethernet signals reliably over substantial distances, preserving data integrity and minimizing latency across the link.
• ST connector for robust fiber interfaces: Featuring a standard ST optical interface, it provides a secure, bayonet-style connection that’s widely compatible with MMF cables used in enterprise networks. The rugged ST port helps ensure stable operation in environments with movement or vibration that might affect looser connector types.
• Plug‑and‑play simplicity with no driver requirement: Install in minutes by simply connecting the RJ‑45 copper port to your Ethernet device and the MMF fiber to the ST port, then applying power. No software or driver installation is needed, making it an ideal fit for quick network upgrades or temporary deployments.
• Compact, durable design with practical power options: The converter’s metal enclosure is built to withstand everyday office use, and its compact footprint makes it easy to deploy on a desktop, shelf, or in a small equipment rack. It’s a low‑power, fanless design that stays quietly out of the way while delivering dependable performance.

how to install StarTech.com 10/100 Multi Mode Fiber Copper Fast Ethernet Media Converter ST 2 km

• Power the unit: Connect the included power adapter to the media converter and plug it into an appropriate power outlet to power the device.
• Prepare connections: Identify your Ethernet device (switch, router, or PC) and the multimode fiber cable with an ST connector. Ensure the fiber type and distance are suitable for your network plan.
• Connect copper side: Attach the Ethernet device’s port to the RJ‑45 copper port on the media converter using a standard Ethernet cable. Ensure the cable is firmly seated and the device is powered.
• Connect fiber side: Plug the multimode fiber cable into the ST port on the converter, aligning the connector and twisting it to lock it in place as required by the ST interface.
• Verify operation: Observe the LED indicators—Power should be on, and both the Copper Link and FX Link LEDs should illuminate when a link is established. If either side does not light, recheck connections, cable quality, and distance compliance.

Frequently asked questions

• Q: What does this StarTech media converter do? A: It converts Ethernet signals from copper (RJ‑45) to optical signals over multimode fiber (ST), enabling Fast Ethernet connections to traverse longer distances than copper cabling alone.
• Q: What speed does it support? A: The device supports 10/100 Mbps Fast Ethernet, auto‑negotiating to the best speed available with connected devices. It does not support Gigabit Ethernet (1000 Mbps).
• Q: How far can it extend the network? A: It can extend a network over multimode fiber up to 2 kilometers, making it suitable for building-to-building links and campus deployments where copper runs are impractical.
• Q: Is it plug-and-play? A: Yes. No drivers are required; you simply connect the copper device to the RJ‑45 port, attach the fiber cable to the ST port, and power the unit.
• Q: Do I need to configure anything? A: In most cases, no configuration is necessary. The converter auto‑negotiates the link and operates in a transparent manner, but you should verify that the connected devices support Fast Ethernet and that the fiber distance is within the supported limit.
