Whats the difference between CAT5e, CAT6, CAT6a, CAT7, CAT8
Your network's performance can either be an asset or a bottleneck for your small business. The type of Ethernet cable you choose plays a critical role in determining how fast and reliable that network is. Let's help demystify the categories of Ethernet cables, helping you make the right choice for your business.
Ethernet Cables: What You Really Need to Know
Before diving into the various types of Ethernet cables, it's crucial to get familiar with some key characteristics that can significantly influence your network performance:
- Speed: This is how quickly data can travel through your cables, generally represented in Gigabits per second (Gbps). Don't forget that your switches, routers, and other hardware also need to support these speeds for optimal performance.
- Maximum Cable Run: This refers to how far the cable can stretch while still delivering a reliable signal. It's usually quantified in metres, and going beyond these limits can result in reduced speeds or data loss.
- Shielding: Many cables come with metallic shielding to help minimise electromagnetic interference (EMI). This is vital in busy office environments filled with electronic devices.
- Outdoor Suitability: Not all cables are cut out for the elements. If you're considering running cables outside for surveillance cameras or other outdoor tech, make sure to go for options specifically designed for outdoor use, featuring UV and weather resistance.
By understanding these aspects, you'll be better equipped to make an informed decision that suits your unique networking needs, both indoors and outdoors.
