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.
