Is It Worthwhile to Use Cat 7 Ethernet Cable?


The-Differences-between-CAT5e-CAT6-and-CAT6A-CablesEthernet cables provide a stable internet connection between electrical devices, which are standardized cables to facilitate easy communication between disparate electronic equipment. These electronic devices can either be fax machines, printers, scanners, or personal computers. Ethernet cables can be categorized into several types based on different specifications. Category 7 Ethernet cable, also refers to Cat 7, which is the wire used for cabling infrastructure of Gigabit Ethernet. it is known that Cat7 is the more expensive option compared to Cat 5e and Cat 6 cables. Users might be wondering whether it is worth the extra money to consider Cat 7 cables. The answer to this solution will be clearly introduced in this passage.

Quick Review of Cat 7 Cables

The Cat 7 cable refers to the transmission cord standard cable used in the 10G Ethernet and other Cat 5/Cat 6 downhill compatible networks. The Cat 7 cable is an 8-core safeguarded cable that each pair of cable has a shield. The program of Cat 7 cables is incompatible with RJ45. A Cat 7 cables can offer the performance of up to 600MHz, which is 6 times as fast as cat 5e and 2. 4 times as fast as cat 6. Besides this, Cat 7 cable, whilst being the more expensive option, is also considered the most durable, and has a longer lifespan than Cat 5 and Cat 6, improving its overall return on investment, and is the best choice for wiring with the future in mind.

Comparing Cat 7 Ethernet Cable With Cat 5/Cat 6 Cables

The mostly used Ethernet cables are not a brand name or generic, they are separated into different standard categories like Cat 5, Cat 5e, Cat 6 and Cat 7. Each one of them is backward compatible, meaning that you can plug a newer cable into a device created for a slower cable, and you will not have any compatibility problems. For companies that are still using the older Ethernet cables, maybe it is time for them to upgrade to a newer version. Cat 7 as the newly released category, opposes the better performance than the former Category Ethernet cables. The following chart shows the distinctions in different Ethernet Categories.


Cat 7 cables require its twisted wires to be fully shielded known as Screen Shielded Twisted Pair (SSTP) or Screened Foiled Twisted Pair (SFTP) wiring, which completely eliminates alien crosstalk while significantly improving noise resistance. Thus it allows the user to get higher possible speeds even with longer cables. When compared at lengths of 100 meters of cable, the following numbers show the difference in Ethernet cable categories:

Cat 5 Ethernet cable is typically too slow for business networks, allowing the user to transmit up to 100 Mb/second speed at 100 Mhz. Cat 5e Ethernet cable allows up to 1 Gb/s internet speed with 100 Mhz. Cat 6 Ethernet cable allows up to 1 Gb/s, but cable lengths up to 55 meters can get internet speeds of 10 Gb/s at 250 Mhz. Cat 7 Ethernet cable is the newest cable category, operating at speeds of 10 Gb/s at 100 meters of cable and transmitting frequencies up to 600 Mhz.

Why Implementing Cat 7 Cable?

SSTP-CAT7-CABLE-23AWGAs noted before, Cat 7 cable is able to achieve higher transmission speed and longer distances than the preceding Ethernet cables like Cat 5, Cat 5e, and Cat 6 cables. What’s more, Cat 7 has an overall shield as well as individual shielding of every pair. Therefore it is much more resilient to interference compared to a CAT 5 cable. The picture shows an SSTP Cat 7 cable.

To better meet the future demand, Cat 7 cables is a dispensable solution as it can create an expandable and flexible cabling system which will save you the expense of re-wiring for new features in the future! One point that we shouldn’t miss out is that Cat 7 cable has a copper cross-section than the Cat 5, which means the individual cores in Cat 7 are easier to work with. Then opt for Cat 7 cables will benefit you a lot.

Solid or Stranded Ethernet Cables

This refers to different methods the wires used within the cable. The solid cable uses one single piece of copper for an electrical conductor. The stranded cable uses multiple (and thinner) copper cables twisted together for the electrical conductor. This makes the stranded cable more flexible, perfect for navigating a complex space. The solid cable is far less flexible making it ideal for permanent installation in the walls or outdoor. This wiring method is not suitable for fiber optic cables like ST-LC patch cord.

Our Recommendations

In summary, careful planning and product selection will be the key to a successful installation. The resolution, distance, signal types, environment, and physical layout are the important factors that you should consider when choosing a transmission media. Cat 7 cable can support 10 Gigabit Ethernet with plenty of margins to spare, and it has the pair-sharing capability, making it possible to use one cable to power several different devices at the same time utilizing each pair as needed.
