Subclause 22.214.171.124.1 of the IEEE 802.3 Standard defines a test channel to be used in the testing of the jitter on the reference clock of 1000BASE-T devices. The channel consists of two short segments of 120m UTP Category 5 compliant cable, along with one (or two, if necessary) long (the exact length is dependent upon the attenuation of the entire channel) segment of 100m UTP Category 5 compliant cable. The channel is to meet or exceed the insertion loss, crosstalk, and return loss requirements as specified in clause 40.7. The objective of this paper is to outline and describe, in detail, the specifications defined in subclause 126.96.36.199.1 of the IEEE 802.3-2002 standard for the Jitter Test Channel, and observe the results of the testing of a completed test channel. Included are plots, outlining the characteristics of the constructed test channel, along with the limits of each specific test.
