Top Features to Consider When Buying WAN Ethernet Cables

In the vast digital landscape, the internet’s arteries are the Ethernet cables that connect devices and ensure seamless data flow. When it comes to Wide Area Networks (WAN), the choice of cables is crucial to garantire a reliable and efficient connection. Navigating the myriad of options can be daunting, but understanding these key features will empower you to make an informed decision:

1. Cable Category:

The cable category defines the performance capabilities of the cable. Higher categories support faster data rates and longer distances. For WAN connections, Cat5e or Cat6 are suitable options, while Cat7 or Cat8 cables offer even higher speeds and bandwidth.

2. Cable Length:

Determine the appropriate cable length based on the distance between the network devices. Exceeding the recommended length can degrade signal quality and reliability. Opt for cables with a few extra feet to accommodate positioning adjustments.

3. Shielding:

Shielded cables shield the copper conductors from electromagnetic interference (EMI), which can disrupt signal transmission. Shielded twisted pair (STP) cables are ideal for environments with high EMI, such as industrial areas or near electrical equipment.

4. Conductor Material:

Ethernet cables use copper or copper-clad aluminum (CCA) as conductors. Pure copper cables offer superior conductivity and durability, while CCA cables are more cost-effective but may have slightly lower performance.

5. Stranding:

Cables can have solid or stranded conductors. Stranded cables consist of multiple smaller wires twisted together, making them more flexible and resistant to bending. This flexibility is crucial for WAN environments where cables are often routed through tight spaces or over long distances.

6. Connector Type:

WAN Ethernet cables typically use RJ45 connectors at both ends. These connectors are designed to be easy to terminate onto the cable and provide a secure connection. Ensure the connectors are compatible with your network devices.

7. Certification:

Look for Ethernet cables that have been certified by reputable testing organizations, such as the TIA (Telecommunications Industry Association) or the ISO (International Organization for Standardization). This certification guarantees that the cables meet industry standards for performance and reliability.


Selecting the right WAN Ethernet cables is vital for maintaining a stable and high-speed network connection. By considering factors such as cable category, length, shielding, conductor material, stranding, connector type, and certification, you can ensure you choose cables that meet your specific requirements and deliver optimal performance for your WAN setup.
