Tripp Lite Cat8 25G/40G Solid Core S/FTP Bulk Ethernet Cable, CMR Rated, Blue, 1000 ft. (305 m)

The Tripp Lite N226-01K-BL is a bulk spool of Cat8 Ethernet cable that lets network installers build custom-length runs capable of 25 Gbps and 40 Gbps throughput. The spool holds 1000 ft (305 m) of solid-core 22 AWG copper, so you can wire an entire row of server racks or several telecommunications closets without hunting for multiple shorter cables.

This cable supports frequencies up to 2 GHz, which keeps latency low and headroom high for voice, video, and large data transfers. Each twisted pair is wrapped in foil, and a braided overall shield surrounds the bundle to block electromagnetic and radio-frequency interference that often appears near power lines, HVAC equipment, or densely packed switches. The result is a stable link that holds negotiated speeds even in electrically noisy spaces.

The blue jacket carries a CMR flame rating, making the cable suitable for vertical risers and other building pathways that require enhanced fire resistance. The color also helps technicians trace runs quickly during moves, adds, and changes. Because the cable aligns with IEEE 802.3, TIA 568.2-D, and ISO/IEC 11801 specifications, it connects seamlessly to Cat8-rated patch panels, keystone jacks, and network hardware from any compliant vendor.

Whether you manage a data center, an enterprise campus, or a test lab that pushes ever-higher bandwidth, this spool gives you the flexibility to cut precise lengths, keep signal integrity intact, and stay ready for the next round of speed upgrades.
