10.2 Interconnect Cables
10.2.1 Cat X
NOTICE
Transmission problems
Routing over an active network component, such as an ethernet hub, switch, or router is not allowed. Operation
with several patch fields is possible.
Establish a point-to-point connection.
Avoid routing Cat X cables along power cables.
NOTICE
Exceeding the limit of the device class
The use of unshielded Cat X cables with higher electromagnetic emissions/radiation can exceed the limit values for
the specified device class.
Correctly install shielded Cat X cable throughout interconnection, to maintain regulatory EMC compliance.
NOTICE
Exceeding limit values for electromagnetic radiation
The limit values for the electromagnetic radiation of the device are complied with if ferrites are mounted on both
sides of all Cat X cables near the device. With installed ferrites, the devices meet the EU guidelines for
electromagnetic compatibility. The operation of the devices without mounted ferrites leads to a loss of conformity
with the EU directives.
Mount ferrites on both sides of all Cat X cables near the device to maintain regulatory EMC compliance.
Type of Interconnect Cable
The extender modules require interconnect cabling specified for Gigabit Ethernet (1000BASE-T). The use of solid
core (AWG24), shielded, Cat 5e (or better) is recommended.
Type of cable
Specification
Cat X installation cable
AWG24
S/UTP (Cat 5e) cable according to EIA/TIA-568, standard 568-A or 568-B. Four pairs of
wires AWG24.
We recommend using standard 568-A, but standard 568-B is also supported.
Cat X patch cable
AWG26/8
S/UTP (Cat 5e) cable according to EIA/TIA-568, standard 568-A or 568-B. Four pairs of
wires AWG26/8.
We recommend using standard 568-A, but standard 568-B is also supported.
The use of flexible cables (patch cables) type AWG26/8 is possible. However, the maximum possible extension
distance is halved.
