AudioQuest Pearl Fiber Optic Digital Cable

Pearl Is the Entry Point to AudioQuest's Optical Range

A fiber optic cable carries sound as pulses of light, not electricity, so it can't pick up the electrical or radio-frequency noise a copper cable can. What still matters is fiber quality and how cleanly the ends are polished.

AudioQuest's Pearl is the first rung of its optical cable line, built around a specially optimized low-dispersion fiber conductor, and it is the only AudioQuest optical tier sold both as a full-size Toslink cable and as a dedicated 3.5mm Mini-Toslink cable.

Low-Dispersion Fiber Conductor

AudioQuest says dispersed light still gets through a fiber, but only after taking a longer path and arriving late, like a pool ball bouncing off the side rails, and that delay prevents the receiving device from decoding the signal properly. Pearl's specially optimized low-dispersion fiber is built to enhance fidelity by reducing that delayed light.

Finely Polished, Low-Jitter Interface

Every AudioQuest optical tier, Pearl included, carries a finely polished optical interface and is built for low jitter at the connection. The Mini-Toslink version of Pearl adds a PVC jacket, which AudioQuest says protects the interior cable and components from dust, moisture and breakages, the only AudioQuest optical tier whose page names a jacket material at all.

The Connectors, Explained

Pearl ships in two forms: a full-size Toslink cable with a square plug on each end, and a 3.5mm Mini-Toslink cable with a mini plug on one end for a laptop or compact source and a full-size Toslink plug on the other for your receiver or DAC.

Who Is This Fiber Optic Cable Best For?

• You are upgrading from the cable that came in the box — Pearl is AudioQuest's entry point, built around its low-dispersion fiber conductor at the lowest price in the range
• Your source has a full-size Toslink optical port — the standard Pearl cable is built for that connector
• Your source has a 3.5mm mini-optical port instead, common on laptops — Pearl is the only AudioQuest tier that comes in a dedicated Mini-Toslink version for that jack
• You want the low-jitter, finely polished interface every AudioQuest optical tier carries — that construction standard starts here, at Pearl
• Your only digital connection is coaxial, HDMI or USB rather than optical — a coaxial digital cable or the matching cable type is what you need instead

How Does It Connect to Your System?

Plug the square Toslink end into the OPTICAL OUT port on your source and the matching square plug into the OPTICAL IN port on your receiver or DAC. If your source has a 3.5mm mini-optical jack instead of a full-size port, common on laptops and some streamers, order the 3.5mm Mini-Toslink version of this same cable instead.

Then power up the system as usual. Other and longer lengths available. Call for prices.

Pairs Well With

An optical cable is one link between a source and a receiver, DAC or soundbar. It usually joins these categories.

• Digital-to-Analog Converters — the most common destination for an optical signal
• CD Players and Transports — a common optical source for a receiver or DAC
• Home Theater Receivers — the usual optical input for a TV or soundbar feed
• Music Streamers — a source component that often carries an optical output

Frequently Asked Questions

What is a Mini Adaptor, and do I need one?

It is a small plug that lets a full-size Toslink cable also fit a 3.5mm mini-optical jack. Pearl is the only AudioQuest tier sold as a dedicated Mini-Toslink cable instead of a bundled adaptor; Forest, Cinnamon, Carbon and Vodka all ship the adaptor in the box rather than a separate cable.

Why does fiber quality matter in an optical cable?

AudioQuest explains it this way: dispersed light does get through a Toslink cable, but only after taking a longer path, arriving late, like a pool ball bouncing off the rails. That delayed light prevents the receiving device from decoding the signal properly. Less dispersion in the fiber means less distortion in the final analog sound.

Is this a glass or plastic fiber?

It's plastic optical fiber, not glass. Every maker in this category describes it the same way: unlike glass, it will not microscopically fracture when the cable is bent or flexed, which is what lets these cables route through tight spots without breaking.

Does an optical cable carry any electrical signal at all?

Light travels down the fiber core with no electrical current on the cable itself, which is exactly why it can't pick up hum, ground loops or radio-frequency noise the way a copper interconnect can. The signal is decoded back to an electrical one only inside your components.

Is there a step up?

AudioQuest Forest is the next rung. It moves to a high-purity fiber conductor and adds solid .5% silver conductors, and it ships with a Mini Adaptor in the box.
