The Evolution of Ethernet Cables: Cat6 vs. Cat7 vs. Cat8

l to modern technology, transmitting signals and electricity between many devices. There are many types of wires, each of which is built with different configurations to suit other applications. Demystifying cables includes learning how cables work, how they are built, and the usage areas. Here are some cable types and what they are used to:

Coaxial Cables:

A coaxial cable is a copper cable built with a metal shield and many other components to block signal interference. It was invented in 1880. TV cable companies mostly use them to connect many satellite antennas to customer antennas in their homes and businesses. Some telephone companies also use them to connect central offices to telephone poles.

Ethernet Cables:

Ethernet cables are mainly used for wiring computer networks and data transfer. Ethernet cables have many types, but the most known and commonly used are CAT5e and CAT6, which supports high data transmission speeds. CAT5e and CAT6 cables are mainly used in homes, data centers, or offices.

HDMI Cables:

High-Definition Multimedia Interface cables provide high-quality video and audio transmission between devices. They are mainly used in DVD players, computers, gaming consoles, or Televisions. HDMI cables are essential for connecting multimedia devices with high resolution.

USB Cables:

Universal Serial Bus cables are mainly used to connect devices to computers, laptops, or other devices for data and power transmission or charging. There are many USB types, such as USB 2.0, USB 3.0, USB 3.1, and USB Type-C. Each type has different data and power transmission speeds.

Power Cables:

These cables are designed to transfer electrical power from a source into devices. Many types of power cables have different voltage ratings or connector types. These cables are mainly used in industrial and commercial settings to provide electricity to many devices.

Fiber Optic Cables:

Fiber Optic cables are the fastest data-transmitting cables using pulses of light while also being one of the most useful cable types for long-distance communication. They are built with thin strands of glass or plastic material called optical fibers, which enable carrying large amounts of data with nearly no signal loss. These cables are mainly used for internet connections, telecommunication systems, and network infrastructures.

Audio Cables:

Audio Cables connect audio between devices such as headphones, musical instruments, speakers, or microphones. The most commonly known audio cable types are RCA, External Line Return (XLR), or Tip-Ring-Sleeve (TRS) cable. Each of them is suitable for different audio signal requirements. These cables are crucial for Professional sound systems and high-quality audio production.

A Brief Overview of Cable Technology

With the evolution of cable technology, we are provided the transmission of information, signals, and power over long distances. Early stages of cable evolution started with Telegraph cables in the mid 19th- century. These cables used copper wires to transmit electrical signals, revolutionizing long-distance communication. After the first evolution, coaxial cables developed in the early 20th century and revolutionized signal transmission once more. Coaxial cables provided better signal quality and enabled higher transmission speeds. In the early 1970s, Optical Fiber Cables were first developed; they were made of glass fibers which enabled fast data transmission over long distances with nearly no signal loss. Ethernet Cables were introduced in the 1980s as an essential part of local area networks and computer networking. With the evolution of ethernet cables, data transmission speeds hit 10 Mpbs to gigabit speeds. High Definition Multimedia Interface and DisplayPort cables enabled high-definition audio and video transmission between devices. Supporting resolutions up to 8K quality. Universal Serial Bus (USB) revolutionized the connection between devices and computers; it enabled versatile data transfer and electricity transmission. USB technology evolves yearly with new versions that provide faster data transfer and more storage. Lastly, wireless connections gained popularity with the evolution of wireless technologies such as Wi-Fi, Bluetooth, and cellular network. This evolution cut the need for physical devices or cables, allowing wireless data transfer and connection between devices with nearly the same transmission speeds.

Understanding Cable Types and Their Uses

There are seven types of cables, each with different usage areas. Ethernet and Optic Fiber Cables are mostly used for internet connection or data transfer. HDMI and Audio cables are mainly used for video and audio transmission, Power cables for electricity transmission, and USBs provide portable data transfer and connecting devices with Bluetooth technology.

Factors to Consider When Choosing Cables

Customers must choose the correct type of cable they need; otherwise, it can cause bottlenecks, and electrical problems, which may break the device or cause data loss. An example is if a customer uses USB 2.0 port with USB 3.1 device, they won’t have the full benefits of the device. They also need to check the voltage on the device they want to use; for example, you can have the same power cable with different voltage levels, leading to battery failure over time or completely breaking it.

Cable Length and Signal Quality

Cable length and signal quality are important topics within cable technology. In contrast, old cable Technologies had a minimal range of signal transmission, Fiber Optic cables are currently the best option for signal quality over long distances while having the fastest data transmission; HDMI Fiber Optic Cables are essential for long-distance high-quality audio and video transmissions. CAT 6A and CAT7 ethernet cables are honorable mentions for long-distance data transmission in network areas or data centers. If a customer needs a small to medium-length cable for broadcasting or CCTV systems, a solid option is Coaxial Cables with low loss.

Connector Types and Compatibility

There are many Connector types, each with a different job in connecting devices. USB-A is a standard connector mostly found in computers and USB hubs and is compatible with USB-A-B-C connectors. USB-B is mostly used on printers and external hard drives and is compatible with USB-A-B connectors. USB-C is a connector mainly used in smartphones and tablets; it is compatible with USB-A-B-C connectors. For HDMIs, we have HDMI-A, which is the standard connector for many devices, HDMI-C, which is a mini version mostly used in tables and other small devices; HDMI-D is the micro version that is used for smartphones and some tablets. For high-resolution video and audio, we can use DisplayPort, which has a standard version, a Mini version for laptops and monitors, and an Alternate Mode to connect to USB-C devices. The most common ethernet connector is RJ-45 which is compatible with most ethernet cables such as Cat5 and Cat6. Audio connectors such as 3.5mm TRS are the most commonly used audio connectors in smartphones and headphones, and XLR is commonly used for high-end audio equipment. Lastly, Coaxial connectors are used for radio and video signals, BNC is mostly used for CCTV systems and broadcasting, and F-Type is used for TV connections and satellites.

Cable Management and Organization Tips

For cable management and organization, we recommend labeling your cables first; making tags or color-coding them will save you space and time. Using straps, cable ties, and cable clips will save you a lot of space. Check your device for a pre-built-in cable management interface; if there is none, you can always buy cable management accessories.
