Copper Ports Tests
The Copper Test page displays the results of integrated cable tests performed on copper cables by the
Virtual Cable Tester (VCT).
VCT performs two types of tests:

Time Domain Reflectometry (TDR) technology tests the quality and characteristics of a copper cable
attached to a port. Cables of up to 140 meters long can be tested. These results are displayed in the
Test Results block of the Copper Test page.
•
DSP-based tests are performed on active GE links to measure cable length. These results are
displayed in the Advanced Information block of the Copper Test page.

•
(Mandatory) Disable Short Reach mode (see the Port Management > Green Ethernet > Properties
page)
•
