97 6. Diagnostics 6.1 OMNIScanner’ s Diagnostic Functions OMNIScanner has several advanced diagnostic test functions to help you with the identification of network cabling faults. Diagnostics allows you to locate opens, breaks, and short circuits as well as NEXT and Return Loss cabling faults quickly and easily.
98 OMNISCANNER The OMNIRemote icon on the right side indicates the wiring at the OMNIRemote end of the cable link. Correct connectivity: The measured lengths of pairs 1-2, 3-6, 4-5, and 7-8 are shown on the left side of the Wiremap.
99 Wires are shorted: Wiremap finds shorts in cable. In this example, the wiremap indicates that wires 4-5 are shorted. Use the number on the left side of the screen to find the exact location of the short. For example if 36 ft is displayed, the short can be found 36 feet away from OMNIScanner.
100 OMNISCANNER 6.3 TDNXT NEXT faults are diagnosed by using the TDNXT (Time Domain NEXT) function. OMNIScanner uses TDNXT to determine the amount of NEXT as a function of distance. TDNXT with new S-Band technology (Standard Connector band technology) can help you to distinguish between connection and cable faults.
101 the NEXT at the connection point, which is typically located at the end of the test cable at 2 meters (7 ft). The measurement unit for the horizontal graph can be displayed in meters (m) or feet (ft). (See Chapter 3, Setup for further information about units.
102 OMNISCANNER 6.3.2 TDNXT E XAMPLES The following examples show the diagnostics process that is performed to identify failures on typical links with 2 meter test cables. GOOD CABLE, BAD CONNECTION: The cursor in the NEXT graph is located at the worst NEXT at 144.
103 BAD CABLE, GOOD CONNECTION: The cursor in the NEXT graph is located at the worst NEXT at 6.2 MHz, which is outside the limit line. (For display purposes the cursor is moved to the Zero- position.) The Link failed. Why? Press to open the TDNXT screen to further review and diagnose the graph.
104 OMNISCANNER The following table summarizes the typical diagnosis process. NEXT TDNXT exceeds Conclusion S-Band limits PASS N/A NEXT at link is good FAIL YES Connection fails. Replace or reterminate. Plug and/or jack can be at fault. FAIL NO Cable is not within specifications 6.
105 S-Bands provide a time domain limit to verify that the connections are within the desired category of performance. In a typical link, failures are a result of either a non-compliant connection or a faulty cable.
106 OMNISCANNER The example shows a Time Domain Return Loss that exceeds the S-Bands. The worst Return Loss is displayed at 7.0 ft, the connection. The conclusion is that the reflection at the connection is the cause of the failure. This could be due to a connector problem or excessively untwisted pairs at the connector.
107 Press to open the TDRL screen to further review and diagnose the graph. The cursor is positioned at the worst peak, which is outside the S-Bands. Looking at the TDRL graph we can reach the conclusion that the connection located at 2 meters did not meet the required performance and is the cause of failure.
108 OMNISCANNER Press to open the TDRL screen to further review and diagnose the graph. The Return Loss response from the connector located at 2 m is well within the S-Bands and performs significantly better than the requirements.
