Every type of cable has a maximum distance. These distance limits can vary greatly from one type of cable to the next. Along with determining whether a cable will work, distance limits will also determine how well a cable works. Knowing the fundamentals behind cable distance limits is the first step in selecting the best cable for your needs.
Key Takeaways
- Every audio and video cable has a practical distance limit.
- Longer cable runs can increase signal degradation.
- Cable quality and construction can affect real-world performance.
- HDMI, DisplayPort, VGA, DVI, RCA, XLR, Toslink, and other cable types have different practical distance limits.
- Higher-resolution video generally requires greater attention to cable quality and signal bandwidth.
- Avoid unnecessary couplers and connections on long cable runs.
- Use active cables, boosters, baluns, or fibre-based solutions when passive cables cannot reliably support the required distance.
- Shielding can help reduce the effects of electromagnetic

3.5mm jacks, also called headphone jacks, are the most common type of audio cable. There are different variations of the 3.5mm audio jack, such as the smaller 2.5mm and the larger ¼”, but they are all functionally similar. 3.5mm cables are commonly available as off-the-shelf items, but sometimes a repair it easier than a replacement. Other times, users need a custom size not available as a standard cable.
Key Takeaways
- 3.5mm cables are widely used for headphones, speakers, computers, smartphones, car audio, and other audio equipment.
- The main 3.5mm connector configurations include TS, TRS, and TRRS.
- Always verify the wiring configuration before making or repairing a cable.
- Use suitable audio cables, connectors, soldering tools, and strain relief for DIY projects.
- Inspect and document existing wiring before removing a damaged connector.
- Use a multimeter to check continuity and identify short circuits before connecting the repaired cable.
- Poor solder joints and damaged shielding can

Audio and video cables go hand-in-hand, often being paired together. Some cables can even transmit audio and video on just one line. Over time a lot of new audio and video cables have been introduced, so the cable you need will often depend on the age of the equipment you are using. Most TVs, computers, and other devices can use multiple types of audio and video connections, so it is good to be able to identify them and know your options.
Key Takeaways
- Audio and video cables connect equipment and transmit analogue or digital sound and image signals.
- Common audio cables include XLR, RCA, 3.5mm, TRS, speaker, and digital audio cables.
- Common video cables include HDMI, DisplayPort, DVI, VGA, composite, component, S-Video, and BNC cables.
- Some interfaces, such as HDMI, can transmit both audio and video.
- Always identify the connector and signal type before selecting a cable.
- Cable length, shielding, construction, and signal requirements can affect system performance.
