category cabling intended to support 10 Gigabit applications over a distance of 100 meters At the request of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 Committee, TIA agreed to specify augmented category cabling systems and components to 500 MHz in order to support 10GBASE-T The project was assigned to TR-42.7 under Engineering Committee TR-42 The TR-42.7 Sub-Committee cooperated with several groups related to this activity TIA standards documents are developed within the Technical Committees of the TIA and the standards coordinating committees of the TIA standards board Members of the committees serve voluntarily and without commission The companies that they represent are not necessarily members of the TIA The standards developed within the TIA represent a consensus of the broad expertise on the subject This expertise comes from within the TIA as well as those outside of the TIA that have an expressed interest The viewpoint expressed at the time that this standard was approved was from the contributors’ experience and the state of the art at that time Users are encouraged to verify that they have the latest revision of the standard This standard has been prepared by the TR-42.7 Subcommittee and approved by the Engineering Committee TR-42 There are 10 annexes in this Standard Annexes A, B, C, D, E, F, G, H, I, and J, are normative and considered a mandatory part of this Standard Annex K is informative and not considered a part of this Standard vii 04/06/06 SP-3-4426-AD10-B, draft 4.0 (to be published asTIA/EIA-568-B.2-10) Annex H Impedance controlled measurement fixture (normative) H.1 10 11 12 13 14 15 16 General The impedance controlled measurement fixture consists of a metal plated pyramid with slots in each side designed to accept the twisted pair leads of a DUT (device under test) The slots are designed to maintain correct differential and common mode characteristic impedance of the pairs in the transmission line when they are separated for mating to the test fixture The pyramid also provides shielding for the pairs to reduce unwanted pair-to-pair coupling The pyramid is electrically connected to the balun ground plane through pin and socket connectors The pyramid, as shown in figure H.1, is mounted to an adapter plate that provides pin and socket connections for the test leads of the DUT A second adapter plate with longer pin and socket connectors is mounted between the balun mounting plate/ground plane and the pyramid adapter plate A common mode termination adapter (which provides common mode with differential mode resistor terminations for the inactive pairs) replaces the long pin through adapter when making FEXT loss (and optionally NEXT loss) measurements PYRASY LPTHRU THIFACE3 17 18 19 Figure H.1 - Test head assembly THI3KIT with baluns attached 20 21 22 23 24 25 26 27 Calibration standards are provided which use the same materials and positioning as the pyramid adapter The calibration reference plane (when performed correctly) is located at the top (open end) of the sockets of the pyramid adapter plate NOTE - All test fixture components referenced in this annex may be obtained from: Superior Modular Products, Inc, Swannanoa, NC 28778 Alternative equivalent components may also be used 76 SP-3-4426-AD10-B, draft 4.0 (to be published as TIA/EIA-568-B.2-10) 10 H.2 04/06/06 Additional components for connection to a network analyzer SMA cables, connectors, 50Ω SMA terminations, mounting fixtures, etc Foil tape with conductive adhesive (3M 5012C or equivalent) NOTES, The balun interfaces are designed to mate to the BH 0050-0092 baluns It is recommend using some copper foil tape as a shield A shield between the long pin adapters as shown in figure H.2 can also be created 11 12 13 Figure H.2 - Test head assembly showing foil tape applied to baluns and shielding (optional) between baluns 14 H.3 15 H.3.1 16 17 18 19 The open, short, and load calibrations

test lead to fit into the pyramid slot as shown in figure H.5 Attach a differential mode termination adapter (DMTERM23) to the pyramid adapter so that the through connecting pins connect to the near-end of the wire pair and the resistor termination connects to the far-end Perform a 1-port (open-short-load) calibration of the near-end balun using the calibration standards and the LPTHRU adapter Remove the LPTHRU adapter from the balun mounting plate Attach the pyramid assembly including the test lead to the balun mounting plate and measure the test lead return loss CMTERM 23 20 21

delay determined with an open circuit at the plug ends at 50 MHz (TDopen _ 50 MHz ) and 100 MHz (TDopen _ 100 MHz ) for each pair SP-3-4426-AD10-B, draft 4.0 (to be published asTIA/EIA-568-B.2-10) Place a short on the plug This short shall connect the pins of the pair under test at the tip of the plug and be no further than mm (0.12 in) from the point of contact Measure the S11 delay for each pair at 50 MHz (TDshort _ 50 MHz ) and 100 MHz (TDshort _ 100 MHz ) sequentially shorted in this manner A recommended procedure for establishing a suitable short delay correction is as follows: Select a plug that can be used for this procedure and is then discarded Three or more plugs are recommended Mount the plug rigidly onto a pyramid or other suitable impedance management fixture Measure the S11 round trip delay of the plug mated to the shorting jack on all pairs and record these value as Delayround trip plug jack Without removing the plug from the pyramid, trim the plastic ribs separating the blades, and solder a wire across all blades where they make contact with the jack Measure the S11 round trip delay of the plug on all pairs and record these value as Delayround trip plug To these values, subtract picoseconds for pairs 1,2; 4,5; and 7,8 and 14 picoseconds for pair 3,6 to account for the delay of the short spanning the plug blades Record these values as Delayadjusted round trip plug Determine the difference in round trip delay for each pair of the shorting jack as follows: Shorting Jack (round trip delay)= Delayround trip plug jack - Delayadjusted round trip plug When measuring the open and short delays for the test plug, the shorting jack values will need to be modified by the delay values calculated in step to determine the one way port extension (PE one way) as follows: PE one way = (Open(avg 50-100MHz)+(Short(avg 50-100MHz) – Shorting Jack(avg 50-100 MHz)))/4 The time delay for each wire pair is determined by the average of the open and short circuit time delay measurements at 50 MHz and 100 MHz (four numbers averaged) These time delay measurements represent round-trip time delays The one-way time delay is ½ of the round trip S11 delay For the purpose of NEXT loss measurements for each pair, the one-way time delays of the wire pairs involved in the measurement shall be used to set the port extension amount for each port as calculated in equation (H-1) PortExtension = TDopen _ 50 MHz + TDopen _ 100 MHz + TDshort _ 50 MHz + TDshort _ 100 MHz (H-1) NOTES, The time delay measurements are dependent on proximity to ground planes The positioning of the wire pairs should remain as constant as possible during all measurements The measurement accuracy of this method is approximately 20 ps in a round trip measurement, corresponding to a one-way distance of approximately mm (0.8 in) When the test plug NEXT loss is measured, the appropriate port extensions shall be applied after calibration to align the tp-rj data and the reference planes corresponding to the jack vector specified in table I.1 of ANSI/TIA/EIA-568-B.2-1 This may be done by turning port extensions of the network analyzer on and entering the calculated port extension constant for each port (1 and 2) of the network analyzer 82 SP-3-4426-AD10-B, draft 4.0 (to be published as TIA/EIA-568-B.2-10) 04/06/06 H.10 Alternative port extension procedure The following procedure is recommended for measuring the delay of each pair of the DUT for port extensions Create a reference short by applying copper foil tape to the mating face of a modular plug as shown in figure H.10 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 Figure H.10 - Example of coaxial test head shorting plug Measure the S11 open and short delay (round trip delay) of each pair of the FEXT coaxial termination reference test head Calculate the average of these two measurements for each pair Divide the result by two (one way delay) (Measure the open delay with the fixture unterminated Measure the short delay with the shorting plug mated to the fixture.) Mate the test plug to the coaxial termination reference test head Use common mode impedance management of the plug leads Measure the through delay of each pair (S12), and record the result Calculate the delay of each pair of the test plug as the difference between the one way delay calculated in step and the through delay measured in step Subtract ps for pairs 12, 45, and 78, and 15 ps for pair 36 to obtain the port extension for each pair Average the time delay from steps through at 50 MHz and 100 MHz When the port extension values calculated according to equation (H-2) are applied to each port (for each pair) the reference planes of measurement will be aligned to the contact point at the nose of the plug PortExtension = TDthrough _ 50 MHz + TDthrough _ 100 MHz − TDopen _ 50 MHz + TDopen _ 100 MHz + TDshort _ 50 MHz + TDshort _ 100 MHz 28 29 83 (H-2) 04/06/06 SP-3-4426-AD10-B, draft 4.0 (to be published asTIA/EIA-568-B.2-10) Annex I Accuracy requirements for level IIIe field testers (normative) I.1 General 10 11 12 13 14 15 16 The level IIIe requirements in this annex are stated for baseline performance, permanent link and channel configurations The field tester performance for the channel and permanent link shall apply to the performance at the reference plane as shown in TIA/EIA-568-B-2.1, figures and respectively 17 I.2 18 19 20 The requirements in this annex shall apply in addition those stated in ANSI/TIA/EIA-568-B.2-1 Where requirements are tighter, the tighter requirements shall apply The methods to compare results from field testers with those obtained using laboratory equipment as defined in ANSI/TIA/EIA-568-B.2, The comparison measurement procedures in this annex shall apply except as stated in ANSI/TIA/EIA-568-B.2 The methods to compare results from field testers with those obtained using laboratory equipment as defined in annex J of ANSI/TIA/EIA-568-B.2 shall apply, except that the optional the “scatter plot method” as described in clause J.4.2 shall be replaced by the method described in clause I.2 of this annex The observed accuracy from comparison methods shall be in harmony with predicted measurement accuracy from performance parameters as defined in this annex Measurement performance requirements Table I.1 – Level IIIe field tester accuracy performance 21 Parameter Baseline field tester Dynamic range Amplitude resolution Frequency range and resolution Dynamic Accuracy NEXT Dynamic Accuracy ELFEXT Source/load return loss Random Noise Floor Field tester with Level IIIe permanent link adapter dB over test limit PP NEXT and FEXT 65 dB 1) PS NEXT and FEXT 62 dB 2) 0.1 Field tester with Level IIIe channel adapter dB dB – 31.25 MHz: 150 kHz 31.25–100 MHz:250 kHz 100 MHz – 250 MHz:500 kHz 250 MHz – 500 MHz: MHz ± 0.75 3) MHz ± 1.0 4) dB dB 20 – 12.5 log(f/100), 20 dB max 12.5 dB 18 – 12.5 log(f/100), 20 dB max., 12 dB 100 – 15 log(f/100) 90 dB max 95 – 15 log(f/100) 85 dB max dB dB Residual NEXT 65 – 20 log(f/100) 5) 60 – 20 log(f/100) 5,7) 54 – 20 log(f/100) 5) dB Residual FEXT 65 – 20 log(f/100) 5) 65 – 20 log(f/100) 5,8) 43.1 – 20 log(f/100) 5) dB Output Signal Balance Common Mode Rejection 40 -
