How Long Can Optical Cables Be?

Is Optical better than coaxial?

The answer to this will depend on the kit you’re using.

If it’s a straight choice between coaxial and optical, we’d go for the former.

In our experience, a coaxial connection tends to produce better audio quality than optical, allowing for a higher level of detail and greater dynamics..

Do optical audio cables really make a difference?

If you’re transmitting PCM, the audiophile answer is that different optical cables can cause different amounts of jitter. The reality is, the digital-to-analog converter in your gear has vastly more effect on the sound. Could a “better” optical cable result in audibly better PCM sound? Doubtful.

What is the best optical audio cable to buy?

What are the benefits of an optical audio cable?

A potential benefit of optical connections is that they won’t be affected by electrical interference. In theory, coaxial could be. Another consideration is that the sound quality may vary by device. Before you hear a digital audio signal it needs to be converted to analog audio.

What is the difference between optical and Toslink?

Yes that is the correct cable. Toslink and optical are just different names for the same thing.

How can I test my optical audio cable?

An optical audio cable should have a red light at each of the connectors when it’s in place and working correctly. If you don’t see the light at either of the ends, the cable isn’t connected properly, is broken, or you might just have a faulty cable.

Should I use PCM or Dolby Digital?

Distinguished Member. Dolby Digital is compressed so PCM is better. Dolby True HD, DTS HD MA, Atmos and DTS X are also lossless, so should be similar quality to PCM. If the source audio is stereo, it should only be coming from your front left and right speakers unless you use an up mixer.

Does length of optical audio cable matter?

Length. Any length that is over 10 meters is a poor choice as it causes the reliability of the transmission to go down. Most optical audio cables will not be longer than 5 meters without a signal booster.

Do optical audio cables go bad?

Well, an optical cable won’t “go bad” in the sense of wearing out or corroding, but it can break, which has pretty much the same result. Such a cable is little more than a bundle of glass or plastic fibres and if you bend one of them too far, it snaps like a piece of vermicelli.

Why is my optical cable not working?

The optical cable may be faulty. Your TV isn’t updated with the latest software version. The connected third-party sound bar, or home theater system may not be compatible with your TV.

Can optical carry Dolby Atmos?

Optical cables don’t carry Atmos, however. Connecting a source like Blu-ray directly to the receiver/sound bar has another benefit: Dolby True HD and DTS Master Audio. These higher-fidelity formats can’t be sent over ARC.

Is optical cable better than HDMI?

Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables). … Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio.

Do Audiophile USB cables make a difference?

As we see, there is no difference between the worst performing USB cable (long and generic) and the shortest one (USB stub). High performance DACs are liable to be even more immune to such vagaries, completely neutering any electrical advantage to shorter, better USB connections.

What is better optical or RCA cable?

If the distance is sufficiently less than 50′, within the length of available optical cables, use optical. If not, you’ll have to use the RCA cables. If it sounds good, fine. If you get hum or RF rubbish, look for a better system.

Is Optical better than Bluetooth?

So yes, compared to Bluetooth specs to date, the optical will be of better quality. Neither will be as good as HDMI cable, which allows eight channels at 192kHz sampling and 24-bits/sample to be transferred, uncompressed.

Do Ethernet cables affect sound quality?

The Ethernet cable is [also] a big problem. It runs long and can pick up low-frequency noise which cannot be filtered out. This noise will introduce jitter at low frequencies which no PLL circuit can get rid of and it will affect sound quality a lot.

Is Optical better than arc?

HDMI ARC and optical cables both share the same purpose. They both transmit multi-channel audio from one device to another. So far, so good. The only significant difference in terms of function is that an optical cable won’t transmit video.

Can you use HDMI and optical audio at the same time?

However, you can’t have the sound coming from both HDMI and Optical at the same time, tho. You can have video from HDMI at the TV’s resolution, and have audio coming from your receiver via optical, which is what I did, or you can have both audio and video going straight to your television, but you can’t have both.

Are thicker optical cables better?

Yes, thicker optical cables are more flexible, with a higher tensile strength than copper or steel fibers, low power loss, and has a much greater bandwidth.

Are there different sizes of optical cables?

There are different types of optical, but again, other than better build quality, a fibre-optic is the same whatever the price. The main difference is hybrid TOSlink connections, where one end is a 3.5mm headphone plug, and the other end a conventional optical connector, which Apple use for most of their computers.
