Shielding helps shielded plenum cables reduce electromagnetic interference (EMI) and crosstalk by limiting unwanted electrical noise from reaching the conductors. In areas with nearby motors, power wiring, or other noise sources, proper grounding and termination of the shield can help maintain signal integrity for security, networking, and AV connections.

Choose Cat 6 shielded plenum cable for network installations that need shielded, plenum-rated Category cable with 550 MHz performance and support for high-speed data transmission. Choose Cat 6A when the project calls for 600 MHz performance, 10 Gbps transmission over runs up to 328 feet, or added crosstalk and electromagnetic interference protection through U/FTP shielding.

When routing shielded plenum cables through air-handling spaces, raised floors, or drop ceilings, use cable marked CMP or another locally approved plenum rating, and follow applicable electrical, fire, and building codes. Route and support the cable to protect the jacket and shielding, maintain required clearances, and terminate or bond the shield according to the system design and manufacturer instructions.

Conductor count should match the number of circuits or signal pairs required, while wire gauge, such as 18 AWG or 22 AWG, helps determine conductor capacity and installation requirements. Choose the cable construction based on the application, including stranded or solid conductors, category-rated twisted pairs for networking, and shielded or U/FTP designs for projects where electromagnetic interference and crosstalk control matter.
