Description

Description

LANmark-7A 1200 is a 4 pair S/FTP cable with individual pair foils and an overall braid offering superior performance up to 1200MHz. It is fully compliant with the new Category 7A standard and offers even large headroom above the Cat 7A requirement. Due to this excellent electrical performance and positive ACR up to 1200MHz the cable is suited for transmission channels with a capacity of >40Gbps.

 

Application

LANmark-7A is the highest performing standardised cabling solution in the market and will support all current data applications and all planned applications using cabling up to Class FA (see discussions at IEEE about 40/100Gbps).

  • All Ethernet applications including
  • 10/100/1000Base-T
  • 1000Base-TX
  • 10GBase-T
  • CaTV up to 862MHz
  • Cable sharing applications including CATV
  • Any future Class FA application

 

Installation

Ease of Installation is one of the main features of the LANmark-7A cable. Extra attention has been paid to ensure that the screen coverage is maintained and foils do not open during installation. The cable has been specially designed to be used in conjunction with the LANmark-7A GG45 12C connector.

To support the correct set-up of hand held analysers for installation testing, the actual cable NVP value is given in the cable’s print legend.
