HDMI is the most common audio/video cable used today. Ushered in as the new standard for the digital age, HDMI was created in a joint project by numerous electronics manufacturers who wanted to set the stage as the switch from analog to digital technology was made. The development of HDMI cables began in 2002 and was completed the following year. Each following year saw more and more HDMI-ready products enter the market. Electronics equipped with HDMI ports became readily available across the world in the coming decade, with an estimated 3 billion HDMI-ready devices made by more than 1,300 companies as of HDMI’s 10-year anniversary in 2013.
While HDMI has been around for some time now, the technology has continued to evolve since its invention. The current standard for HDMI is version 2.0, which was introduced in 2013. This was the first version of HDMI fully capable of supporting 4k signals, which have become increasingly popular for televisions, computer monitors, and projectors. While newer versions of HDMI do exist, they exceed the specs most televisions and other electronics are currently capable of supporting. Since version 2.0 cables are more cost-effective to produce, manufacturers have stuck with them as the standard for the time being. Version 2.0 will eventually become outdated but for the time being, they are considered more than adequate.
While HDMI is certainly the most popular audio/video cable for electronics, it is not the only choice available. DisplayPort is HDMI’s main competitor, also being a digital audio/video cable. While DisplayPort is a little bit better than HDMI, it was designed specifically for use with computer monitors. It is very rare to see DisplayPort on other electronics like televisions or projectors. DVI is an older video-only cable that can be digital or analog, depending on the type of DVI, but cannot perform as well as HDMI. VGA is even older and analog-only, making it the weakest video cable still in use today.
Types of HDMI Cables
Ethernet cable has a major role anytime and anywhere the Internet is involved. Whether Internet connections are used at home or in a professional setting like an office, school, hospital, or manufacturing plant, Ethernet plays a part. Even wireless connections have to get their signals from devices like routers or wireless access points that are using Ethernet themselves. But most people who use the Internet for activities with high data usage, like video streaming, will choose Ethernet for its faster speed over Wi-Fi.
Getting hardline connections ready may sound easy, but there is a bit of a planning process that goes into it. Firstly, think about what type of Ethernet cables you will need. Ethernet is divided into different categories. The current default cable is Cat5e, although newer and faster versions are also available. Consider what kind of data speeds the cable should be expected to handle and make a decision from there. Also, ask yourself where the cable will be located. If it is sitting on a desk in a room-temperature climate, any Ethernet cable will do. But if it will be exposed to extreme temperatures, sunlight, water, oil, chemicals, or any other harsh conditions, make sure to select a cable
Cables are a specialized market where it can be difficult for new or unfamiliar users to separate fact from fiction. Between urban legends on the Internet and all the different options out there, there is misinformation that many people think is true. To clear up these misconceptions and ensure users can make educated purchases, this article will address a few of the fictions that people commonly mistake for facts.
Only Expensive HDMI Cables are 4k – False
Once upon a time, this was true. HDMI has changed over the years as the technology has been upgraded. HDMI cables supporting 4k video became standard back in late 2013. Any HDMI cable on the market today should be more than capable of handling 4k video. If you need a cable with a stronger jacket, then there are better options than a basic cable. But as far as getting a 4k signal goes, a basic HDMI cable will run just as well as an elite one.
Different Color Ethernet Cables Work Differently – False
Ethernet cables can come in any color. Most manufacturers go with simple dark colors like black or blue but some devices like modems might come with a y
Media converter is a bit of a catch-all term by itself. It refers to any device that can convert one type of signal into another type. A fiber media converter specifically refers to a media converter used to convert fiber cable to another format. Fiber media converters are sometimes just called fiber converters while general media converters are simply called converters. The phrase “fiber converters” is also typically used to describe fiber to copper (Ethernet) converters. Although other types of fiber converters do exist, they are much less common.
What are Fiber Media Converters?
Simply put, a fiber media converter is able to take fiber signals and translate them into Ethernet signals, or vice versa. Fiber transmissions are broadcast using light (lasers) signals, giving them a leg up over older cables with increased speed, less attenuation (signal loss), and greater maximum distance per cable. Ethernet signals are transmitted via electrical signals running through copper lines. On their own, these two types of signals are too different to be compatible. But with a fiber media converter, they are able to work together.
Both fiber and Ethernet signals use the same methodology for signal transmission. A series of light or electrical pulses are sent down the cables. These pulses flicker on and off very quickly, 1000s of times per second. When a pulse is on, a computer registers it as a “1”. When it is off, the machine picks up a “0”. These numbers are used to make up binary
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 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.
Fiber optic cables are a first-rate option for transmitting data, being much faster than traditional copper Ethernet lines. Fiber cable can also run for much greater distances, giving it another leg up on copper cables. However, a potential weakness of fiber is fragility. Compared to copper cables, fiber is easier to break since it contains glass. That is where armored fiber optic cables come in.
Armored fiber optic cable can do everything standard fiber can do while also carrying additional protection. Underneath the jacket, there is a metal tube protecting the delicate fibers at the core of the cable. This metal tube does not hamper performance and provides protection from heavy objects, curious rodents, and other hazards. At the same time, the metal remains flexible enough to allow the cable to bend normally.

Advantages of Armored Fiber
All the options available to normal fiber (number of fibers, PVC or plenum jackets, single-mode or multimode, etc.) are also available with armored fiber. The armor allows the cable to withstand 7x the force of conventional fiber, providing a substantially larger safety margin if a heavy object is set on the cable or falls on top of it. The protection offered by armor also increases pull tension, making fiber installations easier
Fiber optic cables provide incredible data speeds and can ensure a new or upgraded system will keep up with network demands for years to come. While the equipment specs are more than good enough to withstand the test of time, it is equally important to build a system that can physically hold up as the years go by. Physical network protection involves using the right tools and equipment to safeguard cables from external forces as well as improper use.
How To Protect Fiber Optic Networks
Raceway, also called conduit, is one of the easiest ways to protect any cable, fiber optic included. These hollow pieces of plastic act like a protective outer shell. They are available as straight sticks as well as various angled pieces for designing networks of any size and shape. Full details regarding raceway options can be seen here.
While raceway is ideal for protecting the main part of the cable, the connectors on the ends will need something a bit
While fiber optic cable has been around for a while, it is only in recent years that new innovations have made the technology economically viable. Fiber has not quite hit the same low pricing as ethernet but is well within the realm of being cost-effective. With the issue of cost set aside, the real question becomes: “Why choose fiber over Ethernet?” These two cables may both be used for data transmission, but they have a few differences along with their similarities.
What are Ethernet Cables?
Ethernet is a tried-and-tested form of cabling, having been in use commercially since the 1980s. These cables are made with copper and use electrical signals to transmit data. Electrical pulses are sent through the cable with each pulse (or lack of a pulse) representing a 1 or 0. This happens very quickly with thousands of signals per second, allowing those 1’s and 0’s to be translated into computer code.
There are a few different types of Ethernet out there. Data speeds can change greatly depending on what type of cable is used plus other factors. While Ethernet signals transmit very fast, they are not quite as fast as fiber optic signals. Using electrical signals also has a major potential drawback: interference. Equipment that gives off electromagnetic interference (EMI) or radio frequency interference (RFI) can disrupt Ethernet signals. This can cause problems in buildings with heavy machinery, such as fact
From left to right: FC, LC, SC, and ST
Fiber optic cables utilize a few different connectors that can be used to terminate the cable. While they do bear some similarities, each kind has a different enough size and shape that they are not interchangeable. When preparing any fiber-related equipment for installation, it is important to make sure the cables are equipped with the right connectors for the job.
FC is an older fiber optic connector currently being phased out of industry standards. While single mode cables still use FC, it is unusual to see them on multimode cables. FC connectors take longer to unplug compared to newer fiber optic connectors due to their threaded screw-on design. Additionally, the more complex design and use of metal make them more costly to manufacture. Despite those downsides, FC still sees some use since those threads allow it to remain secure when used on moving machinery.
LC was designed as a push-pull connector that locks in place with a latch. While being faster and easier to operate is an advantage, the main draw of LC is its small size. Being about half the size of other fiber optic connectors, LC can be used on devices that would otherwise have too little room to support a fiber optic connection.
SC is arguably the most common type of fiber optic connector used today. Designed to be simple to use and inexpensive to produce, SC uses a push-pull design similar to LC but utilizes a locking tab instead of a latch to secure the unit. The cost-effective design of SC makes it a popular choice with industries that frequently use fiber cables, such as telecom and datacom.

For decades, all varieties of cables from coax to ethernet have used electrical signals to transmit signals through metal cores. Modern technology has paved the way for improvements on these age-old cables with fiber optic cabling. These newer cables are made using optical fibers, plastic tubes filled with small pieces of glass. Each piece of glass is used as a tiny mirror to reflect lasers down the cable. Since light (lasers) moves faster than electricity, fiber optic cables can transmit data much faster than older metal-based cables. It is possible to use fiber and Ethernet together so long as you have a media converter, allowing newer technology to upgrade older existing infrastructure.
Each fiber optic cable has a different sized core measured in microns (μm). These cores are made of up optical fibers, also called strands, with each fiber acting like lanes of traffic that send and receive signals. Each fiber can only send or receive a signal, not both at the same time, so they work in pairs. As more fibers are added, more signals can be sent and received through the cable to increase data speeds. The number of strands needed will depend on how heavy network traffic will be.
Along with being faster, fiber optic cables also support greater maximum distances. For example, Ethernet cables have a maximum distance of 328 feet (100 meters). By contrast, fiber optic cables can go for hundreds of meters or even several ki
