Fiber Optic vs. Traditional (Copper) HDMI

Fiber optic HDMI cables are a new, top-of-the-line option for connecting HDMI devices. Using fiber optics technology instead of traditional copper, fiber optic HDMI goes above and beyond the limitations of standard HDMI cables.

Conventional HDMI is made using copper, with multiple smaller copper lines inside the main cable. The main drawback of conventional HDMI is the distance limit. Plain old HDMI caps out at a maximum limit of 65 feet, although depending on the equipment being used, the quality of the cables, and similar factors, issues can start to arise at distances as short as 50 feet.

Up until now, the only workaround to this would be using an extender balun. While HDMI baluns are certainly a fine solution, they are more cumbersome than a single HDMI cable and require a bit more work to set up. They can also have issues with maintaining 4k quality, especially over longer distances. Fiber optic HDMI not only lacks those issues but works even better than a standalone copper HDMI cable at peak performance.

There are a variety of different cables that can be used for video connections. While there have been industry efforts at streamlining, even today there are multiple options on the market. Each type of video cable is easily identified by its unique size and shape, but there are also differences when it comes to the quality of each cable signal. Knowing these differences can enable users to make educated choices when selecting cables for electronic devices.

Of all the different ports that are built into computers today, none is more prominent than the USB port. Every computer, from the most budget-friendly laptop to a high-end liquid-cooled desktop, has at least one USB port somewhere on it. The trouble is when you have a computer with USB ports and not much else. Luckily, USB adapters can be used when you need to change USB into another format.

USB to Ethernet (RJ45)

A lot of modern laptops and even some desktops are built with wireless transceivers for WiFi but no ethernet port for a hardline. So what happens when a wireless connection is too slow while you are trying to stream a TV show or download a movie? A simple USB to Ethernet Adapter can make the computer ethernet ready, giving users much faster download speeds via a reliable hardline connection. Simply plug the adapter in, connect the ethernet cable, and you will be good to go. There is even a version supporting the newer USB Type-C, seen on the latest cell phones and computers.

USB to HDMI

Like any piece of hardware out there, cables can suffer from wear-and-tear as time marches on. Even if cables keep running perfectly as the years go by, they will get to the point of being outdated. Some cables are also more prone to needing replacement than others. Knowing when to replace a cable can make electronics run better, save on your electric bill, and even prevent potential safety issues. But what exactly you need to look for when thinking about replacing something is going to depend on which type of cable we are talking about.

Ethernet – Now or the near-future

Ethernet cables have been through a lot of changes over the years. At the moment, the standard version is Cat5e cable. If the writing on the outside of the cable says Cat5 (or a lower number), it is time to be replaced. Internet service providers today work on the assumption that you are using at least Cat5e cable, as do most websites and other online services.

If you need to upgrade, it is worth taking Cat6 cable into consideration. This is the next step up for Ethernet and will be the new standard once Cat5e is inevitably phased out. Cat6 can support data speeds up to ten times faster than Cat5e. While this is overkill for at-home use right now, upgrading to Cat6 will ensure you do not have to upgrade again for a very long time.

Cables to Keep Around the House

Spring is here and a lot of us are going to use that nicer weather to get a little cleaning done. If your house is anything like everyone else's, there is probably a junk drawer somewhere with a big mess of old cables. After untangling all the knots, you will want to look at each cable to see what you should keep and what can be tossed.

Keep: Micro USB 2.0

Micro USB is better known as a “phone charger” since they are mostly used for Android phones. Not to mention tablets, streaming devices, smart speakers, and more. Micro USB is not going anywhere anytime soon, so keeping a few extras around is a good idea right now.

Keep: Micro USB 3.0

This upgraded Micro USB is mostly used for external hard drives. Some cell phones use these for charging cables too. While not as widespread as the older 2.0 version, this is new enough that hanging onto one or two of them is worth it.

Keep: Lightning

Many electronics have to be connected to a monitor before you can use them. Even devices with their own screens like smartphones and laptops have that option so users have the option of using bigger displays like televisions and projectors. Over the years, many new video cables been introduced and gradually replace the old as technology continues to grow. Modern high-def TVs have come a long way from the black and white TVs of old.

1956: Composite RCA is introduced, becoming a common standard for televisions, VCRs, LaserDisc, video game consoles, computers, and more for the next several decades. Each cable can only send a single signal, paving the way for multi-signal cables to eventually replace RCA in the future.

1979: S-Video is released as a superior (for its time) alternative to composite RCA. It is included on VCRs, home computers, and some early video game consoles up through the early 90s.

1987: VGA was initially created by IBM for their x86 machines. It worked so well that VGA went on to become an industry standard on computers, televisions, projectors, and other electronics. Over time, it becomes the most successful and longest lasting analog connector.

1990s: Component RCA, an upgrade to composite, is developed. While powerful for an analog cable, it has little time to catch on before digital cables start becoming the new standard.

1999: DVI is invented by the Digital

Hooking up a computer monitor is not terribly complicated but there are a few different types of cables that can be used to get the job done. Before even purchasing a monitor, start by checking the computer itself. Look at the back to the machine to see what kind of video ports are on there. Ideally, you will want the same type of connection on the monitor and computer. If you find yourself with a mismatching monitor and computer, you can use an adapter or converter to change one type of connection to another.

When making your selection, there are five main types of connections built onto modern monitors: VGA, DVI, HDMI, DisplayPort, and USB.

VGA

VGA (also called HD15) is an older type of video-only connection. Many used or outdated monitors will have this type of connection while newer models probably will not. VGA is the old standard for monitors and has since been replaced with newer formats. Out of all the monitor connections still in use today, VGA is the only one that is purely analog. This means VGA has a maximum resolution of 640 x 480, a far cry from the 1080p quality available with digital connections. Generally, users only want to use VGA if any of the newer, digital options are not available.

DVI

Cable switches are used to connect multiple signal inputs (computers, DVD players, video game consoles, etc.) to a single output (televisions, computer monitors, etc.). Switches all work on the same general principle and most are purely mechanical. A switch only goes from multiple inputs to one output; if you need to go from one input to multiple outputs, you will need a splitter instead.

Switches are used when you have a screen, such as a TV or computer monitor, that does not have enough ports. For example, say you have a TV with one HDMI port but you want to connect a DVD player, a laptop, and a video game console. One option would be to constantly reach behind the TV and switch the cables, but that gets old fast. The simpler solution would be using a switch that connects all three devices to the TV and lets you change between them at the push of a button.

Most switches are mechanical and do not require a power cable to work. The inside of a switch works similar to switching the rails on train tracks. Say you have a 2-way switch, so the signal can come in from Input A or Input B. If the switch is set to Input A and you press the button to change it to Input B, parts inside the switch move from A to B to change the connection. This is why switches can only use one input at a time. If a switch was built to use multiple signals at once, the signals would interfere with each other and none of them would work.

Coax Cable Switches

Coax cable switches are usually used to switch between an antenna

Coax splitters for Internet and TV are used to connect multiple TVs, computer monitors, or other devices to a single signal source. There are differences between the various types of splitters, but a few general rules apply to them all. Coax splitters only go from one input to multiple outputs; if you need to go from multiple inputs to one output, you need a switch instead.

When a signal goes through a splitter, it is divided and becomes weaker. Imagine an HDMI splitter as an example. Modern HDMI cables are capable of a 4k signal, which works fine if you are using a single HDMI cable by itself. However, say you use a 4-way HDMI splitter to run four cables to four TVs. Each signal would only have half the normal strength so none of the TVs will have 4k quality.

Because the signal is evenly divided, the signal will become weaker for bigger splitters. A 2-way splitter will have signals with ½ the normal strength, a 3-way splitter will have ⅓ the normal strength, etc. This is true even if you are not using every port on the splitter. When a cable splitter is powered on, the signal is split between every port on the unit even if not all of them are in use. For example, if you have a 3-way splitter and are only using two of the ports, each of those two lines will still only have ⅓ the normal signal strength.

Coax Cable Splitters for Internet and TV

Coax cable splitters are used to connect multiple TVs to a single coax line. These splitters are made with F-type female ports, the same type of screw-on connection seen on the backs of most TVs.

Coax splitters can be rated for different Radio Frequency (RF) ratings, measured in MegaHertz (MHz). The MHz range on the spli

Crimp tools, also called crimpers, are used to crimp connectors onto bare wire when assembling a cable. There are a few different versions of crimp tools, depending on how the crimper is made and what type of cable it was designed for.

How Do Crimp Tools Work?

Using a crimp tool is fairly simple. First, a cable must be stripped to expose the metal wire inside. Then the metal wire(s) are inserted into the connector. Single conductor cables (coax) are easier to use than multi-wire cables like ethernet or phone lines (additional details below). Once the wires are inserted, put the connector inside the crimp tool and squeeze the handle. The pressure applied by the crimper will tighten the connector to keep it in place.

Manual vs. Ratchet Crimpers

There are two main types of crimpers, manual and ratchet. Manual crimpers are powered completely by hand. The amount of pressure they can apply to a connector depends entirely on how hard you squeeze the handle. Manual crimpers are harder to use than ratchet crimp tools but are also less expensive. Generally, a manual crimper is the way to go if you plan on using the tool infrequently or for a small number of cables.

Ratchet crimpers are built using ratchets, which allow extra pressure to be applied when crimping. The extra power of a ratchet makes crimping much easier, requiring less raw strength for each individual crimp. This makes ratchet crimpers ideal for frequent usage or when you need to assemble many cables.

Coaxial Crimp Tools

Coaxial crimp tools are rated based on the type of cable they can be used with. The type of connector you are using does not impact whether a tool will be compatible. Since the metal ring where the connector meets the
