BCLS-31YL
CAT6A U/UTP LSZH Cable
Kramer’s BCLS-31YL is a high performance CAT6A U/UTP
cable designed for IT, LAN and Ethernet installations.
Constructed with 23AWG solid bare copper conductors with a
cross filler in a LSZH jacket with internal rip cord and sequential
markings every meter and packed on a fumigated plywood
reel make this cable exceed CAT6A specifications to provide
additional performance and bandwidth over the basic standard
The unique Zigzag jacket design provides excellent performance
of “six around one” bundle transmission
