A shielded Cat6 SFTP cable features both overall and pair shielding to protect against electromagnetic interference (EMI). However, this advantage only works if the shielding layer is properly grounded. If one or both cable ends are not connected to ground, the shield becomes a potential antenna for noise. Always ensure that grounding is continuous throughout the cable route and that connectors are compatible with SFTP shielding.

The 23AWG SFTP Cat6 cable has a larger conductor diameter for better signal transmission, but that also means less flexibility. Many installers bend it too sharply to fit small spaces, causing micro-cracks in the insulation or deformation of the twisted pairs. Maintain a minimum bending radius of at least four times the cable’s outer diameter. Over-bending can lead to signal loss, increased crosstalk, and even long-term mechanical damage.

A common mistake is combining SFTP Cat6 cables with unshielded keystone jacks or patch panels. This breaks the shielding continuity and makes the network vulnerable to interference. Always use matching shielded connectors and ensure that the metallic parts have proper contact with the cable shield.

During installation, some workers pull the cable too hard through conduits or ceilings, especially over long distances. This may stretch the conductors or damage the foil shield. Use cable lubricants if necessary, and never exceed the manufacturer’s recommended pulling tension. Over-tension can reduce performance and shorten cable lifespan.

Routing Ethernet cables parallel to electrical lines introduces strong electromagnetic fields that degrade signal quality. Always maintain a separation of at least 12 inches between network cables and power cables, or use metal conduit separation when necessary. Proper separation ensures the full performance of your Cat6 SFTP high speed network cable.

Even if everything looks perfect, unseen problems such as pair reversal or shield discontinuity may still exist. Always perform a full cable certification test after installation. Testing for NEXT, FEXT, insertion loss, and return loss helps confirm compliance with Cat6 SFTP performance standards.

Temperature, humidity, and UV exposure can all affect cable performance. The blue PVC jacket Cat6 cable is ideal for indoor installation, but not suitable for direct sunlight or outdoor use. For harsh environments, consider LSZH or outdoor-rated alternatives.

Cables thrown loosely across racks or tangled inside trays create maintenance issues and signal interference. Use Velcro straps instead of plastic ties, label both ends of each cable, and organize them neatly. Good cable management extends equipment life and maintains a professional appearance.
