The BCLS-11 (1000') by Kramer is a high-performance Cat 5e U/UTP cable for IT, LAN, and Ethernet installations. Its design exceeds Cat 5e specifications and provides a larger bandwidth than the basic standard cable (sweep frequency up to 350 MHz).
The cable is constructed with four pairs of 24-gauge solid bare-copper conductors. The low-smoke zero-halogen jacket emits limited smoke and no halogen when exposed to high sources of heat, protecting people and equipment from toxic and corrosive gas.
Other features include an internal rip cord to prevent damage to the individual conductors when stripping off the jacket, sequential markings every meter, and a Reelex II carton to help you easily reel out the cable when deploying it.
