Overall Shield: The aluminum foil shielding layer can reduce EMI and RFI, provides stable transmission and offers high specification fidelity for long distance transmission. CAT 6E: 600 MHz speed high-data transfer for networking peripherals and applications that utilize RJ45 connectors including routers, switches, online gaming, video surveillance and streaming, IP cameras, POE power over ethernet, HDMI or HD base-T extenders, computers, laptops and any connection with an RJ45 connector looking to connect to the internet. Pure Copper Conductor: 23 AWG solid pure bare annealed copper for the strongest signal you can achieve in networking pure copper provides better conductivity and enhanced flexibility with an internal Spline to eliminate cross-talk providing exceptional transmission and performance with lowest possible signal loss. CMP (Plenum-Rated): Our cable is designed with your safety in mind. It has the flame retardant grade of CMP/CL3P/FPLP (Plenum-Rated) and is the highest flame retardant cable. This cable suited to go in the plenum spaces of buildings such as ceilings and enclosures, that are also used by the building for air distribution systems to transport air. CMP is higher than commercial grade cable CMR and civil grade cable CM. Attention Please: No RJ45 connectors are on this cable. This bulk ethernet cable is suitable for home improvement or engineering customers who need large-size data cables.
