AudioQuest Carbon Toslink Fiber Optic Digital Cable + Mini Adaptor - 1.5 Meter

What It Does in Your System

A Real Upgrade to the Cable That Came in the Box

Optical is the connection most people never think about — whatever shipped with the soundbar, doing its job well enough. Carbon is AudioQuest's OptiLink series applied to that overlooked link, and it changes what a TV, cable box, streamer, or disc player actually delivers to your DAC or receiver.

At 1.5 meters, this is the everyday length for a rack-to-rack or TV-to-soundbar run, and a 3.5mm mini-optical adaptor is included for laptops and portable players.

Nineteen Fibers Instead of One

A standard Toslink cable uses a single large fiber roughly a millimeter across, and the LED light source sprays into it at many different angles. Light entering off-axis bounces its way down the fiber like a pool ball off the rails, arriving late — the data gets smeared across time and your DAC has a harder job decoding it. Carbon instead uses 19 narrow-aperture, highest-purity synthetic fibers.

Less dispersion means less timing error, and less timing error means a cleaner, more focused analog signal at the other end — better defined transients and a more stable stereo image.

Precision-Polished Ends and Complete Electrical Isolation

The fiber ends are precision polished so light couples cleanly into and out of the cable rather than scattering at the junction, which is where a surprising amount of jitter originates.

And because the connection is entirely non-metallic, it provides galvanic isolation between your components — no electrical path means no ground loops and no transmission or pickup of induced radio-frequency noise. That's an advantage no copper digital cable can offer at any price.

Is This Right for You?

A few things to confirm before you order:

• Check both ends for an optical jack. Look for a small square port, often labeled Optical, Toslink, or Digital Out, sometimes behind a spring-loaded dust flap. If your source only offers HDMI or coaxial digital, this isn't the cable you need.
• Know what optical can and can't carry. Toslink handles two-channel PCM up to 24-bit/96kHz plus Dolby Digital and DTS. It does not carry Dolby Atmos, DTS:X, or multichannel high-resolution audio — those need HDMI.
• Measure the actual path. One and a half meters covers most rack-to-rack and TV-to-soundbar runs. Fiber doesn't like tight bends, so allow a gentle curve rather than pulling it taut around a corner.

Setup & Installation

Pull the protective caps off both ends and press each connector into its optical port until it seats — many jacks have a hinged flap that pushes inward. If either component uses a 3.5mm mini-optical jack, slide the included adaptor onto that end first. Then select the optical or digital input on your receiver or DAC.

Route the cable with a gentle radius and avoid pinching it behind furniture or under a rack foot. Because optical is immune to electrical interference, you can share a path with power cables without any concern about noise — one of the few connections in your system where that's true.

Features & Specifications

19 Narrow-Aperture Synthetic Fiber Conductors
Many narrow fibers replace the single wide fiber of ordinary optical cable, sharply reducing the light dispersion that causes jitter.

Precision-Polished Fiber Ends
Smoothly finished terminations let light couple cleanly at each junction instead of scattering, preserving signal integrity.

Non-Metallic, Galvanically Isolated Connection
No electrical path between components means no ground loops and no transmission or pickup of induced RF noise.

Included 3.5mm Mini-Optical Adaptor
One cable serves both full-size Toslink and mini-optical jacks, covering laptops, portables, and compact components.

Frequently Asked Questions

Will it work with my laptop or portable player?
Yes, if the device has an optical output — including the dual-purpose 3.5mm jacks found on some laptops and high-end portables. The included mini-optical adaptor fits onto one end of the cable for exactly that.

Can it carry Dolby Atmos?
No. Optical supports two-channel PCM up to 24-bit/96kHz along with Dolby Digital and DTS, but object-based formats like Atmos and DTS:X require an HDMI connection.

Does an optical cable really make a difference if it's just ones and zeros?
The data is digital, but the light carrying it behaves in analog fashion. When dispersion inside the fiber smears the arrival timing, your DAC has a harder job and jitter increases. Reducing that dispersion is the entire point of Carbon's 19-fiber construction.
