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.

Cables will always have some sort of “maximum signal” rating, depending on the type of the cable. For Ethernet cables, it will be the maximum upload/download speed. For HDMI cables, it will be the maximum resolution of the video. And so on and so forth for other cables. Any type of “maximum” rating should be taken with a grain of salt.

Those ratings are the best possible rating the cable is capable of under theoretical, perfect conditions. For example, modern HDMI cables are all rated for 4k. But if the HDMI cable is running through a coupler, users will almost certainly not get 4k. Each time a signal passes through a connection, even just connecting a cable to something like a TV or computer, the signal quality degrades a little. Using devices like extenders and couplers will make the signal weaker; for example, coupling a 10’ cable to a 5’ cable will result in a weaker signal than just using a single 15’ cable. Here is where HDMI baluns can help.

Another key factor for signal quality is the distance of the cable. The further a signal has to travel, the more it will degrade by the time it gets from Point A to Point B. Going back to our HDMI example, a 15’ cord will give a clearer image than a 50’ cable. It is possible to get around this issue using an extender/booster. Some cables

Most devices that use USB cables come with one, but these prepackaged cables tend to be too short. Few things are as annoying as having to leave your device in a weird spot to recharge or trying to keep your phone charger from falling off the table. Using USB extension cords to get a little extra distance can be convenient or outright necessary in these situations.

There are a few facts to keep in mind when it comes to USB extension cables. First off, make sure you are picking out the correct type of extension cable. The average USB extension cord is going to be USB 2.0 A Male to Female. Some other types do exist, but typically “USB extension” means an A Male to Female cable.

Another other key detail to check is whether you need a USB 2.0 or 3.0 extension. Usually, the plastic inside the metal end of the USB cable will be color-coded, with 2.0 cables being black or white and 3.0 cables being blue. Not every manufacturer does this, so it never hurts to double-check your cable beforehand. You can use 2.0 extensions with other 3.0 cables, but you will only get USB 2.0 data and recharging speeds. If you want 3.0 speeds, every piece of equipment you are using must be 3.0 rated.
