Your cabling configuration is checked for shield continuity, opens, shorts, crossed pairs, split pairs, and reversed pairs.

  • Page 82: Length/Delay

    • The measured length of the pairs 1-2, 3-6, 4-5, and 7-8 are shown on the left side. In the example, OMNIScanner displays split pairs on 1 - 2 and 4 - 5 although they are wired straight through, a reversed pair 3 - 6, an open on wire 7, and a short on wire 8 to the Shield.

  • Page 83: Next

    OMNISCANNER propagates down the cable (NVP), OMNIScanner then calculates the length of the cable. Skew is the difference between the delay on the longest and shortest wirepairs. The Length/Delay screen shows the test result information for all pairs. The Limit is displayed at the top of the screen.
  • Page 84 CHAPTER 5: Measurements measuring the NEXT for the OMNIRemote end, the roles of the two units are reversed. OMNIScanner provides the termination; OMNIRemote transmits and receives the signal. In the NEXT screen, the worst case margin for all near and far pair combinations is shown at the top of the screen.

  • Page 85: Attenuation

    The Attenuation function measures signal loss in a cable as a function of frequency. OMNIRemote generates and injects a signal at the far end of the cable. OMNIScanner measures the signal at the other end of the cable to determine cable loss.

  • Page 86: Return Loss

    ETURN The Return Loss function measures the uniformity of a cable’s impedance. OMNIScanner injects a signal into the cable and measures the reflected signal strength. Return Loss measures the difference between the transmitted signal delivered to the cable and the reflected signal at the input port of the cable. The reflected signal is the result of impedance mismatches in the link under test.

  • Page 87: Elfext

    ELFEXT is reported in dB and results are computed for twelve pair combinations at the OMNIScanner and OMNIRemote end of the cabling. In the ELFEXT screen, the worst case margin for all near and far pair combinations is shown at the top of the screen.

  • Page 90: Resistance

    Power Sum NEXT is calculated from NEXT for individual pair combinations and takes into account the crosstalk from multiple transmission pairs. When reporting Power Sum NEXT, OMNIScanner displays results for pairs, rather than pair combinations. The PS NEXT measurement is required to assure proper operation of networks employing simultaneous transmission on more than one pair in a link (Gigabit Ethernet, for example).

  • Page 95: Fiber Optic Measurements With Omnifiber

    Propagation Delay is the measure of the time required for a signal to advance from one end of the link to the other. When measuring propagation delay, OMNIScanner measures the round trip delay through both fibers, and then divides the result by two, assuming that the cables are equal in length.

  • Page 96: Loss

    The Loss function measures the signal loss in a fiberoptic cable. The adapters inject a signal into the fiber cable and OMNIScanner and OMNIRemote measure the received signals at 850 and 1300 nm for multimode fiber cables and 1310 for single-mode fiber cables.

  • Page 97: Power Meter

    For dual fiber testing, the arrows at the top of the screen point out the direction of the light and indicate which fiber the result is for. NOTE When measuring single-mode fiber cables, OMNIScanner displays results for the wavelength; the upper (850 nm) section will be blank. Press ESC to edit the LOSS screen.

  • Page 98: Coaxial Measurements With Omniscanner

    The Coax Tests screen displays the measured Length, Impedance, and Termination. The Length function measures the cable length. OMNIScanner will display the overall length in meters or feet. If NEF (No End Found) is displayed instead of a value, the cable is either too long or terminated in its characteristic impedance.

    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. It assists you with diagnosis and troubleshooting of NEXT failures and the verification of test cables, connectors, and plugs.

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.) Initially, the cursor is located at the point with the worst NEXT.

    Return Loss faults are diagnosed by using the TDRL (Time Domain Return Loss) function. OMNIScanner uses TDRL to determine the amount of Return Loss as a function of distance. TDRL with new S-band technology (Standard Connector Band technology) can help you to distinguish and between connection faults and cable faults.

    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.
  • Page 110 CHAPTER 6: Diagnostics 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.
  • Page 111 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. The Return Loss in the cable is the source of the failure even though the cable’s Return Loss...
