The best optical audio cables

In the days before HDMI 2.1 led the digital-decoding landscape, there was the digital optical cable. Known as a TOSLINK cable in some A/V circles, the optical audio cable was pioneered by Toshiba in 1983. Capable of transferring uncompressed audio signals from stand-alone components to an A/V receiver, soundbar, and other types of home theater hardware, an optical cable is a one-and-done purchase you shouldn't skimp on. We've vetted through a plethora of different wire brands to bring you this list of the best optical audio cables.

Best optical audio cables for most people

Pros
  • Fiber optic design
  • Durable design
  • Many length choices
Cons
  • Longer models can get expensive

The KabelDirekt optical cable represents some of the best bang you can get for your buck. According to the company, the gold-plated connectors are corrosion-resistant (not that that matters much in terms of sound quality, but it may improve the life of the cable) and, because of the fiber-optic design, the cable itself won’t have to deal with any interference from radio (RFI) or electromagnetic (EMI) frequencies. The KabelDirekt PVC jacket is flexible and strong to protect the cable over time.

Cheapest but still great

Pros
  • Affordable
  • Braided nylon jacket
Cons
  • Nylon braiding can make them less flexible for tight spaces.

While the FosPower Toslink Digital Optical Cable doesn’t have a set of features that make it vary widely from the rest of the cables on this list, it is priced quite competitively. The cable has gold-plated connectors, and although that matters little in terms of the sound quality, they do offer some anti-corrosion properties and, well, they look cool. The braided nylon mesh jacket makes these cables rugged better protected. It also comes in at a great price.

Frequently Asked Questions

Are optical audio cables the same as fiber optic?

Fiber optics refers to transmitting data via carefully contained pulses of light. That's how the optical audio cables work, so they are generally considered under the fiber optic umbrella. That doesn't mean they're the same thing as cables responsible for fiber optic internet, of course.

The alternative for these kinds of connections is called a "coaxial" digital audio cable. Coaxial cables have a better bandwidth for carrying lots of data at once, but fiber cables are better at resisting interference and lightning faster. You can check your ports to see what type it, specifically, is designed to support.

Should optical audio cables be nylon braided?

A nylon braided jacket is a layer of protection that helps the cable resist cracking and tearing over time, especially when the cable is frequently moved or stepped on. It's not as necessary for audio cables, which tend to spend their time out of the way behind cabinets or shelves. But it's still a protective feature for those who want them, and for those working with A/V equipment that's frequently moved.

What does Toslink mean?

It refers to Toshiba Link, an early name for optical audio cables. The standard has evolved since then, but it's still a label used for high-quality home theater audio connections. You can safely assume that optical audio cables you find are naturally Toslink.

Are optical audio cables better than HDMI?

Audio cables allow for a dedicated audio connection instead of offering both audio and video. That can make them useful in more versatile setups, or connecting surround sound systems when HDMI ports are all otherwise engaged. However, HDMI is capable of carrying high-resolution audio for cinematic audio formats, so it tends to edge ahead as the best option if you're using a new HDMI format, like 2.0 or beyond.
