Patch cable Cat.6, U/UTP, Slim The Slim RJ45 Cat.6 U/UTP patch cable has been specially developed for very dense network environments. The particularly slim cable diameter facilitates installation in narrow patch panels and network cabinets. The halogen-free LSZH jacket is flame-retardant, low-smoke and contributes to greater safety indoors, while the lightweight design allows flexible handling. Bandwidths of up to 250 MHz are possible with pure copper conductors.
