Category 6a (Cat 6a) cable supports up to 10 Gbps bandwidth and can transmit those speeds at distances up to 100 meters, making it the best choice for the scenario where the distance is 55 meters. Category 5 (Cat 5) is rated for speeds only up to 100 Mbps, which is insufficient for the requirement. Category 5e (Cat 5e) supports up to 1 Gbps up to a distance of 100 meters, and while better than Cat 5, it still doesn't meet the 10 Gbps specification. Standard Category 6 (Cat 6) cable can also support 10 Gbps but only up to a distance of 55 meters, placing it at the very limit of the requirement and leading to potential performance issues, especially if there are any non-ideal conditions like EMI or cable bends.
