Cat6 cables are an improvement over Cat5e in terms of speed and performance. These cables are designed to support higher bandwidth, allowing for faster data transmission rates of up to 10Gbps at shorter distances. Cat6 cables are backward compatible with Cat5e devices, making them a popular choice for upgrading existing networks. Their improved specifications and stricter manufacturing standards result in reduced crosstalk and better signal quality, making Cat6 ideal for data-intensive applications, multimedia streaming, and larger network infrastructures.
