A.6 Fixture 40.8.3.1.C
Fixture 40.8.3.1.C is a square pin fixture for MDI return loss. It allows a single Balun to test all 4

The short CAT 5 cable with four pairs of square pints mates to the Balun test fixture for return loss
tests. 100-ohm resistor loads are installed on the channels that are not being tested.
A.7 Fixture 40-28A
Fixture 40-28A is used for the alien crosstalk noise rejection test. It requires one-half meter long
CAT 5 cable with female test pins on the transmit differential (positive and negative) pins at one
end. The transmit differential pins correspond to the orange and orange-white twisted cable pair in
the CAT 5 cable.
