Best Ethernet Cable For A Mac

Not all Ethernet cable is created equally. What’s the difference, and how do you know which you should use? Let’s look at the technical and physical differences in Ethernet cable categories to help us decide. Ethernet cables are grouped into sequentially numbered categories (“cat”) based on different specifications; sometimes the category is updated with further clarification or testing standards (e.g. These categories are how we can easily know what type of cable we need for a specific application.

If you’re still using a Cat 5 cable or simply want to upgrade your old Ethernet cables, there are many enhanced options to choose from. Here are five of the best Ethernet cables on the market. What cable do i use as ethernet cable for my MacBook Pro. It does not have a conventional plug.

What are the differences between the categories and how can you know when to use unshielded, shielded, stranded, or solid cable? Keep reading for “cat”-like enlightenment. Technical differences The differences in cable specifications is not as easy to see as physical changes; so let’s look at what each category does and does not support. Below is a chart for reference when picking cable for your application based on the standards for that category.

As the category number gets higher, so does the speed and Mhz of the wire. This is not a coincidence, because each category brings more stringent testing for eliminating crosstalk (XT) and adding isolation between the wires. This does not mean your experiences have been the same. Physically you can use Cat-5 cable for 1 Gb speeds, and I have personally used cable longer than 100 meters, but because the standard has not been tested for it, you’ll probably have mixed results. Just because you have Cat-6 cable, doesn’t mean you have 1 Gb network speeds either. Every connection in your network needs to support the 1 Gb speed and in some cases, the connection will need to be told in software to use the available speed.

Category 5 cable was revised, and mostly replaced with, Category 5 Enhanced () cable which did not change anything physically in the cable, but instead applied more stringent testing standards for crosstalk. Category 6 was revised with Augmented Category 6 () which provided testing for 500 Mhz communication (compared to Cat-6’s 250 Mhz). The higher communication frequency eliminated alien crosstalk (AXT) which allows for longer range at 10 Gb/s. Physical Differences So how does a physical cable eliminate interference and allow for faster speeds? It does it through wire twisting and isolation. Cable twisting was invented by Alexander Graham Bell in 1881 for use on telephone wires that were run along side power lines. He discovered that by twisting the cable every 3-4 utility poles, it reduced the interference and increased the range.

Twisted pair became the basis for all Ethernet cables to eliminate interference between internal wires (XT), and external wires (AXT). There are two main physical differences between Cat-5 and Cat-6 cables, the number of twists per cm in the wire, and sheath thickness. Cable twisting length is not standardized, but typically there are 1.5-2 twists per cm in Cat-5(e) and 2+ twists per cm in Cat-6.
