Connects Your USB Device to a Wired Ethernet Network without an Internet Card Installed This USB to Ethernet adapter allows you to instantly connect your computer, laptop, tablet or other USB-compatible device to a wired 10/100 Mbps fiber optic network, even if your device has no NIC (Network Interface Controller) installed. The adapter offers access to an Ethernet network when Wi-Fi is unavailable or when a wired connection offers faster speeds. It transmits data up to 20 kilometers (12.4 miles) from your fiber network using a 1310 nm wavelength. Hot-Swappable for Installation Without Network Interruption This USB 2.0 Ethernet adapter is fully hot-swappable, so you can install it without a potentially costly network shutdown or device reboot. Just connect the built-in USB cable to your device's USB port (which also powers the adapter), and wait for the installation process to finish (you may have to reboot your computer). Then, connect the LC duplex port using existing or newly run singlemode fiber cable (such as Tripp Lite's N370-Series, sold separately). Delivers Full Ethernet Performance with Audio and Video Streaming The compact USB to Ethernet adapter supports full 10/100 Mbps network speeds and USB 2.0 speeds, allowing you to transfer data efficiently and stream audio and video. The direct fiber connection minimizes the risk of data leaks and electromagnetic interference (EMI). A blue LED indicates successful Ethernet connection and data transfer. The adapter works with Windows operating systems and is backward compatible with USB 1.1 devices.
