Exceeds the limits established in ANSI/TIA-568-C.2 Standards for CAT.5E/Class D; Channel performance guaranteed for up to 4 connections in channels of up to 100 meters; Injected thermoplastic protective covers ("boot") to prevent "cable fatigue" during connection movements and to prevent accidental disconnection of the station. This protective cover has the same dimensions as the RJ45 plug connector and its structure prevents snagging as it overlaps the plug lock; RJ-45 connectors with double claws that ensure electrical connection with the cable cores.
