A.2 Fixture 40.6.1.1.1.A - Differential Breakout Cable
A short cable is required for the transmitter jitter test and for the alien crosstalk tests. It is
connected to the end of long test cables by using a CAT 5 patch connector and is approximately 10
inches in length. It is a CAT 5 cable with four pairs of square test pins, with one pair on each
differential pair within an inch of one of the male RJ-45 connectors.
A.3 Fixture 40.6.1.1.1 - Test Cable
This cable is used for master and slave transmit jitter (IEEE 802.3, Section 40.6.1.2.5). It is made
from three segments as defined in IEEE 802.3, Section 40.6.1.1.1.
There are two segments with 120-ohm characteristic impedance, and one long CAT 5 cable section
with 100-ohm characteristic impedance. Near the UUT end of this cable, fixture 40.6.1.1.1.A
(above) is attached. Appendix C provides detailed information for the construction of this cable.
