Description
-
Nexans’s LANmark-6A series is their Cat 6A line. But as per Nexans’s website, the standard LANmark-6A options are shielded (e.g. F/FTP) — shielding is used to protect against alien crosstalk at the higher frequencies used by 10G.
-
The datasheet for LANmark-6A shows parts like N100.694G-OC (500 m reel, F/FTP) with LSZH jacket.
-
I found a listing for a “Nexans LANmark-6A U/UTP AWG24 Cat 6A LSZH Dca” (in a networking/UTP cables listing) which suggests they do offer a U/UTP version in LSZH.
-
But detailed performance and datasheet information is scarce for a 305 m U/UTP Cat6A variant from Nexans in public domain.
-
Unshielded Cat6A at 10 G is more sensitive to interference and alien crosstalk. That’s why many Cat6A products are shielded (F/FTP, S/FTP).
-
U/UTP design for Cat6A is more challenging to maintain performance margin at frequencies up to 500 MHz without shielding.
-
Nexans seems to focus their Cat6A offerings on shielded versions for better immunity, which is consistent with many high-performance cable vendors.
Special Variants / Use Cases
-
Nexans also has variants for outdoor / harsh / 5G / in & out usage, with jackets that resist UV, moisture, and environmental stress, while maintaining signal integrity. For example, “Cat.6A 5G S/FTP In & Out” for combined indoor/outdoor use.
-
Their industrial LAN line (LANmark Industry S/FTP Cat 6A) is built for use in more exposed or industrial settings.
