Product information

Description

Connect to a 100Mbps fiber optic network using a laptop or tablet USB-A port with the StarTech.com USB to Fiber Optic Converter (US100A20FXSC). This compact USB 2.0 adapter provides a 100Base-FX SC optical transceiver for multimode fiber links up to 2 km, and is compatible with Windows and Mac. The converter is USB-powered and designed to deliver fiber-to-the-desk connectivity that reduces electronic interference common to copper Ethernet.

Advantages

The adapter enables a secure fiber network connection through a standard USB-A port without requiring internal installation. Its SC duplex multimode optical transceiver supports 100Base-FX links to a maximum range of 2 km. The unit is USB-powered for easy portability and operates with certified drivers for Windows and Linux, allowing plug-and-play setup after driver installation. Using fiber reduces risk of electromagnetic interference and helps protect sensitive data compared with copper cabling.

Suitable for (tasks / use cases)

  • Connecting a laptop or tablet to a multimode fiber network where only USB-A ports are available
  • Temporary or mobile fiber-to-the-desk (FTTD) connections
  • Environments requiring protection from electromagnetic interference
  • Network troubleshooting or device testing with 100Base-FX links

How to use

Plug the converter into an available USB-A (USB 2.0) port on your laptop or tablet. Install the appropriate certified driver for your operating system (Windows or Linux/Mac where supported). Connect a multimode SC duplex fiber cable between the converter and your fiber network. The adapter is powered from the USB port and will establish a 100Base-FX Ethernet link once drivers are installed and the fiber connection is active.

Usage recommendations

Use certified multimode SC duplex fiber cabling and verify link compatibility with your network equipment. Ensure drivers are the current versions from StarTech.com for best interoperability. For mobile or temporary deployments, keep the adapter protected from physical damage and disconnect when not in use to avoid strain on the fiber connector.

Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
