Cat8.1 cable is specially designed for data center applications, specifically “top of rack” and “end of row” topologies. The Cat8 standard is limited to a maximum of 30 meters (100ft.) for 40G speeds. Cat8.1 cable is compatible with RJ45 interfaces.
Cost Savings
Copper cabling is always cheaper to deploy than fiber; copper networks do not need transceivers or the extra power requirements that their fiber counterparts require. A Cat8 network running at 40G over a 30-meter run will not require more power than a 10G network running over 100 meters.
Deployment
Like any other category of cabling, Cat8 can be terminated on-premises; this makes installation easy to manage. Additionally, it is a plug-and-play solution, just like different categories of cable, making setup and use more straightforward and more versatile than equivalent fiber technologies
