How to Assess the Quality and Speed of Cat 7 Shielded Ethernet Cables
Introduction
Cat 7 shielded Ethernet cables are a high-performance cabling solution that can deliver speeds of up to 10 Gbps. They are commonly used in data centers, offices, and other commercial applications where speed and reliability are essential. However, not all Cat 7 cables are created equal, and it is important to know how to assess their quality and speed before making a purchase.
Physical Inspection
One of the first things you should do when assessing a Cat 7 cable is to inspect it physically. Look for any signs of damage, such as cuts, nicks, or kinks in the cable. Also, check the connectors to make sure they are clean and free of any debris.
Connector Type
The type of connector on a Cat 7 cable can also affect its quality and speed. The most common type of connector for Cat 7 cables is the RJ-45 connector. However, some Cat 7 cables also use the GG45 connector, which is a newer and more advanced type of connector. GG45 connectors are designed to provide better performance at higher speeds than RJ-45 connectors.
Cable Shielding
Cat 7 cables are typically shielded to protect them from electromagnetic interference (EMI). EMI can cause data errors and slow down the speed of your network. The type of shielding used on a Cat 7 cable can vary. Some cables use a braided shield, while others use a foil shield. Braided shields are more effective at protecting against EMI than foil shields, but they are also more expensive.
Cable Length
The length of a Cat 7 cable can also affect its speed. The longer the cable, the more likely it is to experience signal loss and interference. For this reason, it is important to use the shortest possible cable that will meet your needs.
Testing
The best way to assess the quality and speed of a Cat 7 cable is to test it. You can use a cable tester to measure the cable’s attenuation, delay skew, and other performance parameters. This will give you a good idea of how well the cable will perform in your network.
By following these tips, you can assess the quality and speed of Cat 7 shielded Ethernet cables and make an informed decision about which cable to purchase. Remember, not all Cat 7 cables are created equal, so it is important to do your research before making a purchase.
