Patch cords with PS-GG45 7_A plugs allow for Class F_A compliant cabling systems (up to 1000 MHz) and for Class F installations (up to 600 MHz). The PS-GG45 7_A plug uses only 4 x 2 contacts in the top nd bottom corners of the PS-GG45 7_A module, whereby best NEXT und RL values can be achieved.
The unused contacts will be connected through a switch to ground. 
Measurement cords with PS-GG45 7_A plugs are primarily needed for acceptance testings.

Future viability

GG45 cabling systems that use standard patch cords (RJ45/RJ45) provide enough electrical reserve capacities for 10-gigabit Ethernet applications (10GBase-T).

When deploying adapter patch cords with one RJ45 and one PS-GG45 plug you can achieve more than 1000 times better reserve capacities in the Channel.

These reserve capacities are large enough also for the transmission of future applications in Class F_A cabling systems up to 1000 MHz.
