You Asked: Are optical cables supposed to be loose?

How do I keep my optical cable in place?

Banned. The best you can do if the cable will not stay in on its own is to tape it. The connection does not have to be tight, just good enough so the light meets the internals. You can hold the TosLink cable close and not be connected at all and get perfect audio as if it were connected.

Can optical cables be faulty?

Like all other cables, the joint between the plug and the cable tubing can come undone. If this happens, the cable may stop working. Further, fiber optic cables are much more sensitive to crimping than standard wire cables. Even pinching the wire too much can cause the fiber optics to get damaged.

How do I know if my optical cable is broken?

To troubleshoot, plug the suspect connector into the VFL and look at its back. If a lot of red light is visible, the connector is bad and should be replaced. If you look from the other end and see light coming only out of the fiber, that indicates a good connector. If the whole ferrule glows, it’s bad.

Does optical input have a red light?

Why can the red LED light to be seen from the DIGITAL OUT (OPTICAL) terminal? The red LED light can be seen from DIGITAL OUT (OPTICAL) when the Digital Audio Connector Adapter is inserted into the TV without an optical cable connected.

How do you test an optical cable?

Test each jumper cable by running a test signal through your cables. Connect your first jumper to the port on the top of the optical source. Plug the other end of the same cable into your optical meter. Then, press the “test” or “signal” button to send a signal from the source to the meter.

Are optical audio cables fragile?

You’ve seen standard S/PDIF connections a bunch too; they’re often called “coax digital.” Optical had certain benefits over copper cables, but they were also more fragile, and for a long time, more expensive.

Is optical better than aux?

Advantages of Optical Input Even though there is not much difference in the audio quality, it is supported by most modern home theaters. When you use optical input with a surround sound system, the result is better than AUX input. It does not require any complex wiring so that the audio quality will not be compromised.

Do high-quality optical cables matter?

When it comes to optical audio cables, the audio cable quality does not really matter since the sound you get from the optical audio cables is the same regardless of the quality you pick. The durability of the optical cable, on the other hand, is one of the factors that will have an impact on the audio quality.

Does optical cable length affect sound quality?

Unless optical S/PDIF is REALLY weird, not it won’t make a difference. With things like SONET and optical Ethernet, any length cable works just as well until you go over the max and attenuation makes your signal not go through.

How long can an optical audio cable be?

around 16 feet A: The ADAT spec puts the limit on optical cable length at five meters (around 16 feet). However, the length you can achieve depends greatly on the cables you are using. Inexpensive optical cables lose signal quite rapidly. But good-quality glass cables can be used for much longer runs.

Should optical cable light up on both ends?

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.

Are fiber optic cables fragile?

Fiber optic cable has typically been categorized as fragile, like glass, which the actual fiber is, of course. But unlike drinking glasses that break when dropped or windows that lose every battle with a kid’s baseball, glass optical fiber is incredibly strong and flexible.

Is optical cable better than HDMI?

The major difference is that HDMI cables can pass higher resolution audio which includes formats found on Blu-ray like Dolby TrueHD and DTS HD Master audio. Fiber optic cables won’t be able to transmit these high-res sound formats. HDMI can also pass video signals.

Should optical cable click in?

When you insert the optical cable, it should click into place. It is designed to fit one way only; one side is squared-off while the opposite is angled on the corners.

Can you use both HDMI and optical audio?

You will be able to insert both – optical and HDMI cords and have the audio and video signals coming through both of them. You’re not sure whether your TV will allow you to do that? You should check the instructions manual that came with your TV. Also, you can simply google it to verify.
