53 EASYLAN 6 Expert mode Below a real case example showing the measurement results and their interpretation: Cable, ft long Cable, 4.92 ft long Cable, ft long RJ45 plug RJ45 plug Note that the cables have different lengths: L1 = ft and L2 = 4.92 ft. The cable under test is ft long. The impedance of the two cables is 120 Ω and that of the cable is 100 Ω. In this real case, the curve below shows the result of a fault location on the measuring unit side. y-axis = Fault amplitude ft x-axis = Distance in ft The displayed curve shows the NEXT evolution in the time domain. The x-axis is the distance in feet from the measuring unit or the remote unit depending on the case. By moving the cursor, the time in ns is displayed. It's the time during which the signal travels distance D represented on the x-axis. A peak with an amplitude quite important represents a fault. Here, we can see a peak around D = ft. This indicates that the fault is located at ft from the measuring unit. The measurement cable measuring ft, the fault is in the cable at ft from the RJ45 plug, close to the measuring unit side. Chapter 6 - page 51

54 On the remote unit side, the fault location curve is as follows: y-axis = Fault amplitude x-axis = Distance in ft We can see a peak at distance D = ft from the remote unit, thus implying a fault in the cable at = ft from the RJ45 plug close to the remote unit side. This result confirms the previous one obtained on the measuring unit side Results and interpretation in Return Loss We can detect anything to do with the reflection field: - Cable mounted with too low bend radius or with kinks and pinches. - Zc mismatch, 100 Ω cable tested with 120 Ω cables. - Bad CP (Consolidation Points). The results obtained in the real test described in the previous paragraph are as follows. From the measuring unit side, the fault location from Return Loss gives the following curve: ft y-axis = Fault amplitude ft x-axis = Distance in ft Chapter 6 - page 52

55 EASYLAN 6 Expert mode We can see three peaks: The first one is located at ft from the measuring unit. It shows a Zc mismatch at level of the RJ45 plug on the measuring unit side. The second one is located at ft from the measuring unit and represents a fault in the cable. This confirms the result previously found when locating faults with NEXT. The third one is located at ft and corresponds to the remote unit position, but not to a fault. The peak having the greater amplitude is the one located at ft. This let us think that the main fault is in the cable. From the remote unit side, we get the following curve: y-axis = Fault amplitude x-axis = Distance in ft Here also, we can see a strong peak located at ft from the remote unit. This confirms the result obtained when locating faults in NEXT. The 4 fault location results (2 in NEXT and 2 in Return Loss) all confirm the presence of a fault in the cable at the same place. ft Chapter 6 - page 53
