This higher frequency allows Cat7 cables to support faster data transfer rates and more stable connections, especially over longer distances. For businesses in Hong Kong that require ultra-high-speed internet, such as those using Hikvision Hong Kong systems, Cat7 may be the better choice.

Shielding and Noise Reduction

Shielding is another critical factor to consider. Cat6A cables typically feature either unshielded (UTP) or shielded (STP) designs, with STP offering better protection against EMI. Cat7 cables, however, are always shielded, often with multiple layers of protection. This makes them highly resistant to interference, which is essential in environments with high electrical noise. For example, a 9U rack setup in a busy office might benefit from the additional shielding provided by Cat7 cables.

Connector Types (RJ45 vs. GG45/TERA)

The type of connector used can also influence your choice. Cat6A cables typically use standard RJ45 connectors, which are widely compatible with existing network equipment. Cat7 cables, on the other hand, often require specialized connectors like GG45 or TERA. While these connectors offer better performance, they can be more expensive and harder to source. This is an important consideration for businesses in Hong Kong looking to minimize installation costs.

Data Transfer Rates

Both Cat6A and Cat7 cables support data transfer rates of up to 10 Gbps, but Cat7 cables can maintain these speeds over longer distances.
