Overview

Kramer’s BCLS−21 is a high−performance CAT 6 U/UTP cable designed for IT, LAN and Ethernet installations. It is constructed with four pairs of 23AWG solid bare copper conductors with a cross filler. It is enclosed in an LSZH jacket with internal rip cord and sequential markings every meter and packed in a Reelex II carton for easy to pull−out.

BCLS−21 cable exceeds CAT 6 specifications to provide additional performance and bandwidth beyond the basic standard.
