exans has announced its new
copper-based solutions to support
bandwidths of 25Gb/s and 40Gb/s
Ethernet. Developing this technology is part
of Nexans’ vision of supporting the world’s
growing data needs.
As Nexans’ LANmark-7A is now
upgraded in frequency from 1000MHz
to 1250MHz to fully cope with the
demands of 25GBase-T. Designed for
applications beyond 10G, LANmark-7A
supports existing RJ45 based legacy
equipment using the backwards-
compatibility of GG45 connectivity.
This technology allows for a seamless
migration to 25G over 30m while being
fully compatible with 10GBaseT over
distances greater than 100m.

Category 7A is currently the highest
performing standard available and
is specified to 1000MHz. Although
25GBase-T will use 1000MHz as upper
frequency some headroom is required
from the cabling. LANmark-7A has
always delivered headroom beyond the
minimum and this change formalises
that for new installations. Existing
installations of LANmark-7A may also
be qualified to support 25GBase-T. screened RJ45 compatible cable jack
specified up to 2000MHz.
LANmark-8, which will also be launched,
is based on LANmark-7A, with
enhancements including the ability to
support frequencies up to 2000MHz,
enabling transmission of 40GBase-T
over 30m. Both systems are based on
Nexans’ GG45 connector, which is a Combined with a LANmark-8 2GHz
cable, GG45 offers support for
40GBase-T.
These developments were designed
specifically to address the challenges
of supporting high frequency Ethernet
applications in excess of 10 Gigabits.
Combined with LANmark-7A cable and
patch cords, GG45 offers support for
25GBase-T.
