Cable Information

Data cables

Data cables are copper or fiber optic cables that are used to transmit data between devices. These come in different types like Ethernet, fiber-optic, HDMI, and coaxial, depending on what you need to transmit and how far the devices are from each other.

Twisted Pair Cables

Twisted pair cables are used in telephone and computer networking. They are specially designed with shielding to prevent signal degradation from other sources. The unique twisting technique used in these cables protects your important data communications from distortion. However, these cables have a transmission limit of up to 300 feet.


Cat5 was a common Ethernet standard, but it is outdated. Its bandwidth was 100 Mbps at distances up to 100 meters. It's not recommended to use Cat5 for networks these days as the cables are not available for sale. So, if you're looking to set up a network, it's probably best to go with a more modern standard.


Cat5e is an enhanced standard of Cat5 cable, apparent by the ‘e’ in its name. These cables are designed to handle speeds of up to 1000 Mbps and are commonly used for Gigabit Ethernet in residential and commercial settings. While it may not be the fastest option available, it is a cost-effective choice. An IEEE standard aims to increase its speed to 5 Gbps over existing cables, also compatible with Cat6 cabling.


Cat6 cabling is wound more tightly and has a nylon spline and shielding to reduce crosstalk and interference. It allows for faster speeds of up to 10 Gbps but only on shorter runs of up to 55 meters. The wires are stiffer and more difficult to terminate, and traditionally more expensive than Cat5e.


If you're looking for a reliable cable that can handle higher speeds, then Cat6a is a great option. The “a” in its name stands for augmented, which means they are thicker and more heavily shielded than previous standards, virtually eliminating crosstalk. They maintain 10 Gbps speeds over longer distances of up to 100 meters, ideal for industrial use but less flexible for residential deployment.

Cat7 & Beyond

Cat7 is a new shielded cable that delivers speeds of up to 100 Gbps for distances of 5 meters or less. It reverts to 10 Gbps at longer distances. Cat8 is still in development, but it promises a bandwidth of 40 Gbps, although no equipment is available just yet. These cables are best suited for data centers rather than homes.

Fiber Optic Cable

Fiber Optic Cable is a fast and reliable option for data connections. This type of cable uses light and glass to transfer data, which means you won't have to worry about any signal issues. Although it's a bit fragile due to its glass components, it's still a great choice for anyone who wants a speedy connection.

Coaxial (Coax)

Coaxial cable is a type of electrical cable used for transmitting high-frequency signals. It consists of a central copper conductor, an insulating layer, a metallic shield, and an outer protective jacket. Coaxial cables are commonly used for CCTV cameras, modems, TVs, and certain types of data networking.
