7 Best Optical Audio Cable Options in 2023

Best Options for Home Theaters, TVs, and More

Optical Audio Cable

There was a time when the digital-decoding scene was dominated by HDMI 2.1; yet, even in that time, there also existed the digital optical cable. Toshiba first developed the optical audio cable in 1983. These cables are often referred to as TOSLINK or Toshiba Link cables within the audio-visual industry.

You only need to buy an optical cable once, so you shouldn’t try to save money on it. That’s because it can transport uncompressed audio signals from solitary components to an A/V receiver, soundbar, and other home theatre equipment.

We have compiled a list of the 7 best optical audio cables you can find in 2023.

So, without any further ado, let’s jump right into it!

What Is an Optical Audio Cable Used For?

An optical cable

We use optical audio cables to transmit digital audio from speakers or AV receivers. They are almost indistinguishable from HDMI cables that consumers often use. Instead of using optical audio cables wherever feasible, attempt to utilize HDMI cables instead. If you’re wondering why you can find the explanation below here:

HDMI cables can transmit higher-quality audio, including Blu-ray codecs, such as Dolby True HD and DTS HD Master Audio. But, this functionality is not present in optical audio cables.

When you have older equipment that does not support HDMI, you can use the optical audio cable in this case. However, you need to do so to get the audio to your AV receiver or soundbar. This is a brief explanation of the usage of optical audio cables.

Things to Consider When Buying an Optical Audio Cables

Below are the things you should keep in mind while buying an optical audio cable:


Any length that is above ten meters is not a good option since it causes the transmission’s reliability to decrease. For example, optical audio cables often cannot be longer than 5 meters without an additional signal booster. For example, suppose you require lengths that are more than one hundred feet.

In that case, the best option for you would be an optical cable made with molten quartz since it will deliver higher-quality results. So, for example, suppose you need only a short cable. In that case, you may use a cable made of plastic optical fibers.

We say this because there will be no noticeable change in the signal’s quality. But only unless the distance between the sender and receiver is more than one hundred feet and the bandwidth levels are very high.


There is no difference in performance between the 5 mm and 8 mm cables. That’s because the width is just the exterior diameter of the cable, which does not influence the connections in any way.

As a result, there is no difference between the two sizes. However, you should know that thicker cables are more long-lasting and often come with a protective nylon mesh covering on the exterior. This is something that you may want to take into consideration.

There is not a significant quality gap between different optical audio cable brands. For example, suppose you do not have remarkable hearing and a very high-rate system. In that case, it is unlikely that you will hear any changes when you use a cheaper brand instead of a more costly one. This is the case even if you own a very good system.


The cost of optical audio cables is often higher than digital coaxial cables due to their higher bandwidth requirements. However, as a trade-off, they provide superior performance when reproducing digital signals since there is no interference from other electronic equipment nearby.

Therefore, the kind of optical cable you choose to invest in will significantly impact the pricing you provide. Plastic fiber cables of standard length, 5 meters, are much more affordable than quartz fiber cables of the same length.

In addition, certain cables come with connectors coated with 24k gold to improve signal transmission and help prevent corrosion. However, this may also significantly drive up the price of the cable.


It is always a good practice to check optical audio cables to ensure they don’t have any sharp kinks since this will prevent it from functioning correctly. Bending the cable inhibits it from passing light correctly along its length, which is acceptable but unavoidable.


Your optical audio cable needs to have a bandwidth that ranges from 9 MHz to 11 MHz for the greatest possible performance. The larger the bandwidth of this connection is, the more effective it will function.

However, it is important to keep in mind that smaller consumer items, such as CD players, would not experience a loss in quality due to limited bandwidth in the same way that a home theatre system would.

Frequently Asked Questions About Optical Audio Cables

Is an optical audio cable better than HDMI?

No, an HDMI cable is better than an optical audio cable.
Optical connections and HDMI cables can carry precise, multi-channel sound, with considerable benefits over more typical analog audio interfaces. On the other hand, you can stream Dolby TrueHD and DTS HD Master Audio through HDMI. However, it is not possible to use optical cables for this purpose. Analog signals are used less

HDMI is capable of transmitting video too. Also, when paired with ARC and eARC technologies, HDMI cables can be a unique cable option for linking your inputs to a TV or ancillary A/V equipment. At the same time, optical cables serve just audio transmission.

Optical cable interfaces are still present on many current gadgets, but HDMI is significantly more widespread. Older HDMI-enabled devices might not have the same audio functionality as newer models. HDMI 1.3 introduced Dolby TrueHD DTS-HD Master audio capability, whereas HDMI 1.3 included the audio return channel (ARC). HDMI 2.1 adds support for eARC in return.

Is an optical audio cable better than RCA?

While many newer systems only need an analog connection, digital connections that utilize optical media are becoming more common in newer systems (RCA). RCA cables combine video and audio transmission into a single cable. RCA cables are often less expensive than optical cables.

Ultimately, it is up to you to choose the kind of connection you will employ. For example, your requirements might differ based on your home theatre system’s components and whether you want stereo sound.

If you are concerned about cost, the RCA cable may be the best choice. But, if it is more vital to be compatible with modern systems that demand digital connections, then the optical cable would be the better choice.

optical audi cable vs RCA

Is an optical cable best for audio?

No, optical cables are not necessarily the best for audio. HDMI is a superior option to these optical cables.

Are optical audio cables still used?

Yes and no.

Throughout the ’90s and ’00s, the optical cable was almost omnipresent. It was the simplest method to transmit Dolby Digital and DTS from a satellite tv box, TiVo, or DVD player to a receiver. Even in the earliest days of HDMI, the optical cable was kept nearby in case a user’s receiver was incompatible with HDMI.

Now, however, an increasing number of devices lack optical. For instance, it has disappeared from the most recent Roku and Apple TV 4K.

It has also vanished from many smaller televisions. However, it persists in bigger televisions as a somewhat unnecessary backup to HDMI with ARC. 

What’s the rationale? Soundbars. Most soundbars continue to use an optical connection, which is one of the few factors keeping the format alive.

On the audio side, devices such as Chromecast Audio use an optical interface owing to space limitations. Chromecast Audio employs the mini-Toslink variation that fits into a 3.5mm analog port.

Are optical audio cables directional?

No, they aren’t. You can use them from both ends.

Does optical audio cable quality matter?


Most of the information you will send across optical connections will be digital, namely audio in the format of PCM (Pulse Code Modulation) or Dolby Digital. If they do not get a flawless signal, all Dolby Digital audio codecs are programmed to shut down entirely.

If any bits are missing or incorrect, the decoder will send out silence rather than risk transmitting something that might potentially harm your speakers. For example, suppose you are receiving a Dolby Digital signal that is no skipping. In that case, the optical connection that you are using is working properly.

Suppose you’re asking an audiophile about jitter. In that case, the answer for PCM transmission is that varied optical cables may create different levels depending on the cable. The truth is that the digital-to-analog converter in your device has a far greater impact on the sound than any other component. So a “better” optical connection might lead to noticeably uncompressed PCM audio.

Are all fiber optic cables the same?

Fiber optic cables often vary in size, even though their fundamental purpose remains to transmit light data. For example, regular Toslink and micro Toslink are the two varieties of fiber optic cables, with the latter being much more condensed, space-saving, and producing better audio quality than the former.

Final Words

Over the course of 2 months, we tested over 20 optical audio cables. The optical audio cables you see on this list are the best 7 among them.

There is an abundance of advantages that come along with using optical audio connections. Since optical signals are used to transport sound waves, the strength or quality of the sound wave is not easily lost, even though it is sent over a long distance. This is because optical signals travel at very high speeds.

The quality of the AUX and RCA ports built into the board is much higher. Therefore, you may find an option for an optical audio connector on the vast majority of current TVs.

However, suppose you are looking for the highest possible quality. In that case, the product that FosPower has to offer should be able to satisfy your needs.
