Cat6a Ethernet Cable 101: Understanding The Different Types

Cat6a Ethernet cable can be your best option if you seek a fast and reliable Ethernet line for your network. It is the latest iteration of Ethernet cables and offers better performance than its predecessor. This article discusses the different Cat6a Ethernet cables available, their features, and how to choose the right one for your network.

What is Cat6a Ethernet Cable?

Cat6a Ethernet cable is a twisted pair cable for transmitting data at high speeds over long distances. It is an upgraded Cat6 Ethernet cable that accommodates up to 10Gbps of transmission at a frequency of 500MHz, making it perfect for high-performance networks.

Types of Cat6a Ethernet Cable

Shielded (STP) Cat6a Ethernet Cable

Shielded Cat6a Ethernet cable has an additional shielding layer around each pair of wires. This shielding helps to reduce crosstalk, electromagnetic interference, and radio frequency interference, which can cause data errors and performance degradation. Shielded Cat6a Ethernet cables are recommended for environments with high levels of electromagnetic interference, such as factories or hospitals.

Unshielded (UTP) Cat6a Ethernet Cable

Unshielded Cat6a Ethernet cable does not have any additional shielding. It is the most commonly used type of Cat6a Ethernet cable and is suitable for most network environments. Unshielded Cat6a Ethernet cables are cheaper and easier to install than shielded cables.

Plenum-rated Cat6a Ethernet Cable

Plenum-rated Cat6a Ethernet cables are built for usage in plenum spaces or spaces in a building where air is circulated, such as the space above a suspended ceiling or below a raised floor. These spaces require special cables that meet specific fire and smoke safety standards. Plenum-rated Cat6a Ethernet cables are more expensive than regular Cat6a Ethernet cables, but they are essential for compliance with building codes and safety regulations.

Riser-rated Cat6a Ethernet Cable

Riser-rated Cat6a Ethernet cables are used in vertical applications, such as between floors in a building. They are designed to prevent the spread of fire from one floor to another and must meet specific safety standards. Riser-rated Cat6a Ethernet cables are less expensive than plenum-rated cables and are suitable for most commercial and residential applications.

Factors to Consider when Choosing the Right Cat6a Ethernet Cable

  1. Distance – Cat6a Ethernet cables can transmit data up to a maximum distance of 100 meters.
  2. Speed – Cat6a Ethernet cables support speeds of up to 10Gbps at a frequency of 500MHz. You may need to use a Cat7 Ethernet cable if you need higher speeds.
  3. Environment – If you’re working in an environment with high electromagnetic interference, you should use shielded Cat6a Ethernet cables. Otherwise, unshielded cables are suitable for most network environments.
  4. Safety standards – If you’re working in a building with specific fire and smoke safety standards, use plenum or riser-rated Cat6a Ethernet cables.


Cat6a Ethernet cable is a high-performance Ethernet cable suitable for most network environments. Several types of Cat6a Ethernet cables are available, each with its own features and benefits. Choosing the suitable Cat6a Ethernet cable depends on your specific needs. Doing so ensures you get the right cable for your setup.
