Green shielded Cat6 Ethernet cable with RJ45 connectors, 19.69ft length

Black Box Corporation

Black Box 19.69ft Cat6 Shielded Stranded Cable Green EVNSL0272GN0020

SKU CH-1EWW-NHQGC

A 19.69 ft shielded Cat6 patch cable with double shielding for EMI and RFI protection in high-noise environments, tested to 250 MHz performance with gold-plated contacts rated for 750 mating cycles

  • Reliable Gigabit performance with 250 MHz tested bandwidth
  • EMI and RFI protection via double shielding with foil and braid
  • Durable connections rated for 750 insertion cycles
  • Superior conductivity from 50 micron gold plated contacts
  • Flexible stranded design suits patching and tight routing

Shielded Cat6 Cable for Noisy Environments

This 19.69ft shielded Cat6 patch cable uses four individually shielded twisted pairs with foil tape and an overall tinned copper braid. The double shielding protects Gigabit Ethernet signals from EMI and RFI interference in high-noise environments. It is tested to the 250-MHz Cat6 standard for reliable voice, data, and audio/video transmission. Gold-plated contacts on the RJ-45 plugs ensure superior conductivity.

Sustained Performance in High-Noise Settings

The double-shielded construction maintains signal integrity during continuous data transfer where electromagnetic interference is present. Foam insulation and foil tape around each pair combine with the overall braid to prevent distortion over the full 19.69ft length. Connectors are rated for 750 insertion and extraction cycles, supporting reliable long-term use in demanding installations. The cable meets or exceeds the industry specification for sustained Cat6 performance.

Practical Limits of the Cat6 Interface

This cable is certified for 250-MHz bandwidth, defining the upper frequency limit for the Cat6 standard it follows. Shielding effectiveness and connector durability of 750 cycles set the physical boundaries for reliable operation. The stranded conductor design suits patching applications rather than permanent in-wall runs. Buyers needing higher bandwidth categories or solid-core cable for structured cabling should select a different product type.

Questions about this item

Does the double-shielded Cat6 cable generate any heat or electrical noise when carrying gigabit traffic all day?

The cable is a passive shielded assembly with foil tape and a tinned copper braid; it produces no heat or electrical noise of its own and the shielding prevents external EMI and RFI from distorting the signal.

What equipment must I already have to use the RJ-45 male connectors on this 19.69 ft patch cable?

You need devices with standard RJ-45 Ethernet ports — such as a switch, router, patch panel or network card — that accept an 8P8C plug.

Will the 250 MHz tested Cat6 cable work with my existing Cat5e patch panel and gigabit switch?

The cable meets the Cat6 standard and is fully backward compatible with Cat5e components, so it will operate at the speed of the connected equipment.
