Typically, the optical cable is less than five meters in length. And you can use the device to transfer audio signals from one device to another.<\/p>\n\n\n\n<p>What are the common audio formats that the optical cable transfers? It transmits DTS multichannel audio, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Dolby_Digital\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Dolby Digital<\/a>, and PCM stereo audio.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"what-is-the-working-principle-of-an-optical-cable\">What Is the Working Principle of an Optical Cable?<\/h3>\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"ebdcd2\" data-has-transparency=\"false\" style=\"--dominant-color: #ebdcd2;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"577\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/1-49-jpg.webp\" alt=\"A man holding an optical cable\" class=\"not-transparent wp-image-8038\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/1-49-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/1-49-300x173.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/1-49-768x443.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A man holding an optical cable<\/em><\/p>\n\n\n\n<p>Optical cables use light to transfer audio digitally instead of the usual copper wire. In short, the optical cable is a variant of fiber optics that works for different applications.<\/p>\n\n\n\n<p>Further, digital optical cables operate with this principle. But the difference is that digital optical cables are specifically for audio-only applications at shorter distances. Additionally, digital optical cables change audio data on the source end from electrical signals (digitally encoded) to light.&nbsp;<\/p>\n\n\n\n<p>Then, an <a href=\"https:\/\/en.wikipedia.org\/wiki\/Light-emitting_diode\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">LED<\/a> light drives the signals to the receiving end via a cable. At this point, the light pulses change back to electrical pulses.&nbsp;<\/p>\n\n\n\n<p>As a result, the audio moves through the connected component for amplification or devices like stereo receivers, home theater, etc.&nbsp;<\/p>\n\n\n\n<p>Afterward, the signal will finally change to analog for you to hear the sound effect through headphones or speakers.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"where-can-you-use-an-optical-cable\">Where Can You Use an Optical Cable?<\/h3>\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"b79181\" data-has-transparency=\"false\" style=\"--dominant-color: #b79181;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"670\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/2-43-jpg.webp\" alt=\"A man inserting the cable into an optical input\" class=\"not-transparent wp-image-8037\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/2-43-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/2-43-300x201.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/2-43-768x515.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A man inserting the cable into an optical input<\/em><\/p>\n\n\n\n<p>Optical cables are useful for telephone lines, cable television, internet, and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Computer_network\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">computer networking<\/a>. Also, you can use these cables for the following:<\/p>\n\n\n\n<ul>\n<li>Transferring data at high speeds in the military industry<\/li>\n\n\n\n<li>The lighting of vehicles in the automotive industry<\/li>\n\n\n\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Endoscopy\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Endoscopy<\/a> in the medical industry<\/li>\n<\/ul>\n\n\n<h3 class=\"wp-block-heading\" id=\"optical-cable-connector-how-does-it-look\">Optical Cable Connector: How Does It Look?<\/h3>\n\n\n<p>In truth, the connectors are different for various devices. And it\u2019s because manufacturers design a device\u2019s connector based on the function. For instance, an external speaker features an input connector, unlike TVs that have output connectors.<\/p>\n\n\n\n<p>Also, optical cables have different ends compared to HDMI cables, which have the same ends. So, it\u2019s crucial to connect the right end to the device.&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"hdmi-cable-what-it-is\">HDMI Cable: What It Is<\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"dcdcda\" data-has-transparency=\"false\" style=\"--dominant-color: #dcdcda;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"600\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/3-34-jpg.webp\" alt=\"A close view of an HDMI cable\" class=\"not-transparent wp-image-8034\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/3-34-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/3-34-300x180.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/01\/3-34-768x461.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A close view of an <a class=\"wpil_keyword_link\" href=\"https:\/\/www.clooms.com\/best-2-1-hdmi-cable-ps5\/\" title=\"HDMI cable\" data-wpil-keyword-link=\"linked\">HDMI cable<\/a><\/em><\/p>\n\n\n\n<p>It\u2019s no surprise that HDMI cables are so popular. After all, they provide an all-in-one solution. Also, these cables offer high-definition transmission for video and audio signals. Hence, you can easily connect your video and audio with the HDMI cable.&nbsp;<\/p>\n\n\n\n<p>Also, it\u2019s a great option for gaming consoles like Xbox One, PS4, etc., as these devices feature HDMI port connections.

In other words, this HDMI is an excellent choice for multitasking on different windows. Also, you can watch movies on your TV from a laptop with this cable. In addition, HDMI cables provide high-definition content when you link the Set-Top Box and gaming console to your television.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"hdmi-connector-how-does-it-look\">HDMI Connector: How Does it Look?<\/h3>\n\n\n<p>The HDMI connector has a design that looks like a USB port. The only difference is that the connector is usually longer than the USB port, with unequal slot side lengths and a trapezium shape. Further, the HDMI connector is typically next to USB ports on laptops, TVs, etc.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"optical-cable-vs-hdmi-cable-the-major-difference\">Optical Cable Vs.

So, if your soundbar or TV lacks an HDMI connector, you can use an optical cable. But it\u2019s crucial to note that this cable won\u2019t support HD audio formats.<\/p>\n\n\n\n<p><strong>Do you need an HDMI cable if you have an optical cable?<\/strong><\/p>\n\n\n\n<p>Yes, you do because it will be the second cable for transmitting your video signal.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"rounding-up\">Rounding Up<\/h2>\n\n\n<p>Optical cables support most PCs and gaming consoles.
