Optical Cable 101: The Basics of Optical Cables

Before you dive into your search of the right optical cable for you; it may be logical to first know what it is, what it does, and what qualities should you look out for.

What is an Optical Cable?

In Crutchfield’s guide on audio and video cables, they have defined an optical cable as a cable that has the capacity to transmit audio signals as light pulses.

Wikipedia explains that an optical audio cable, or optical cable, is also known as TOSLINK cables that were derived from the term “Toshiba Link”. This is because Japanese electronics brand Toshiba was known as the first company to use and standardize the optical fiber connector for their consumer electronics.

Although optical cables are commonly used in connecting consumer electronics and home entertainment systems, some argue that it may not be the best choice for the technologically savvy.

Optical Cable vs. Coaxial Cables vs. HDMI Cables

According to Crutchfield, there are three top choices when it comes to cables that have the capabilities to transmit high-quality digital audio signals. These cables are:  coaxial cables, optical cables, and HDMI cables.

PriceLess PriceyInexpensiveCan be quite expensive

Although a lot of people prefer the HDMI cable, it can be quite expensive and may not always be compatible with your system; especially if you appreciate the more classic models. That is why; you should consider using either optical or coaxial cables.

However, although coaxial cables may be less expensive than HDMI cables just like optical cables; they can be quite hard to find these days. Therefore, the more affordable cable that can fill the gaps left by the expensiveness of HDMI cables and the rarity of the coaxial cables, are the optical cables.

But what are the qualities of a good audio cable?

Qualities of A Good Optical Audio Cable

There are several factors that can define a good optical audio cable, and doityourself.com has summed it up nicely.

  • Optical cables longer than 5 meters require a signal booster. Therefore; you may want to set up your soundbar relatively closer to get the best results.
  • Know which diameter you need and use it. The width of the cable has virtually no bearing in signal transmission.
  • Although the cable diameter does not affect the signal transmission; a thicker cable is found to be tougher than a thinner one due to its outer nylon mesh covering.
  • Set a budget that you want to spend on the cables; this would reduce the limit of your options and make choosing a lot easier.
  • When it comes to bandwidth, the ideal preference is around 9 MHz to 11 MHz.

Aside from these points, you may want to consider the metal used in the connectors because this would aid in the conductivity and ease in signal transmission.

Based on this chart above, it is clear that the ideal metal for conductors is silver with gold plating.

Connecting to the Sound Bar

After considering the material and the components of the optical cable; knowing how many cables you will need to connect it with your sound bar is another crucial consideration. Hence, it is ideal to research on the kind of sound bar you have and how you can connect to it using optical audio cables.
