A fiber optic USB cable is designed to transmit data or audio signals using light instead of traditional copper wires. This can help reduce interference and support longer distances for data transfer. For example, some cables connect computers or gaming consoles to audio systems using optical signals, while others extend USB connections over long distances for devices like VR headsets or network adapters. Always check the product details to make sure the cable matches your device's ports and intended use.

Most fiber optic USB cables on this page are made for connecting computers, laptops, gaming consoles, or audio equipment—not directly for TVs. Some products specifically mention they're not compatible with TVs. It's important to review the product description and your TV's available ports before purchasing. If your TV supports USB or optical audio connections, double-check the cable's compatibility to avoid connection issues.

• Plug the USB end of the adapter into your computer or compatible device.
• Connect the optical (TOSLINK or SPDIF) end to your audio receiver, soundbar, or amplifier.
• Some adapters may require you to select the correct audio output in your device's settings.
• Check for any included instructions for specific setup steps.

Setup can vary by device, so it's a good idea to consult your device's manual or the adapter's instructions for best results.

Some fiber optic USB cables are designed to support high-speed data transfer and digital audio, which can be useful for gaming headsets—especially with VR systems or gaming PCs. However, not all cables are compatible with every headset or console. Be sure to check the product details for supported devices and audio formats, like stereo or surround sound, to make sure it fits your gaming setup.

• First, double-check that all connections are secure and the cable is plugged into the correct ports.
• Try restarting your devices after connecting the cable.
• Look for any required drivers or settings adjustments in your device’s audio or USB settings.
• If possible, test the cable with another device to rule out hardware issues.

If you continue to have trouble, review the product’s instructions or reach out to Walmart’s customer support for further help.
