UY o amd48f eps Figure B 5 Modified Method B Smart Remote Mode Test Connections B 10 The Alternate Method Like Method B A 1 the alternate method produces results that account for the loss of two connections plus the fiber in the link An advantage of this method is that you can test links that have different connector styles at each end Figure B 6 shows reference and test connections for the alternate method The link under test has MT RJ connectors at one end and LC connectors at the other end Using an SC to MT RJ patch cord and an SC to LC patch cord for reference and test connections may seem like an easier way to connect to the link however that would require an MT RJ to LC patch cord for reference connections The reference and test connections would be the Method C A 3 configuration as shown in Figure B 3 The loss results would account for the loss of only the fiber in the link Loss Test Methods for Fiber Cabling The Alternate Method To account for the loss of both connections in the link you must add connections to each end after referencing as shown at the bottom of Figure B 6 Each fiber path then has four connections Since two connections were canceled out during referencing the test results include the loss of the two connections at the ends of the link You may also use the alternate method to test links that have the same connector style at both ends As with

6. DTX Series CableAnalyzer Technical Reference Handbook Return Loss Return loss is the difference between the power of a transmitted signal and the power of the signals reflected back The signal reflections are caused by variations in the cable s impedance Figure 3 18 shows some common sources of reflections that create return loss High return loss means the cabling reflects very little of the transmitted signal back to the source High return loss is especially important for high speed systems such as Gigabit Ethernet The bi directional full duplex transceivers used in these systems use directional couplers to distinguish between incoming and outgoing signals The couplers may interpret strong reflected signals as incoming data resulting in data errors A return loss plot indicates how well a cable s impedance matches its rated impedance over a range of frequencies Figure 3 19 describes the return loss plot For return loss failures the testers diagnostic screens D Fault Info may show more than one possible cause for the failure In this case you can use the HDTDR analyzer results to further diagnose the problem See Chapter 5 for details Note For ANSI TIA EIA 568 B 2 3 and ISO IEC 11801 2002 6 4 2 standards return loss is not evaluated where insertion loss at the same frequency is less than 3 dB If insertion loss never exceeds 3 db return loss results are marked with anion the tester and an N A in LinkWar

The reference is incorrect Set the reference again using the same reference test cords to be used for testing For multimode fiber the wrong mandrel size was used for testing Smaller mandrels create tighter bends in the fiber resulting in more loss A reference test cord or fiber segment has the wrong core size An OTDR is useful for locating mismatched fibers The cabling has a bad fusion or mechanical splice or a sharp bend Use the visual fault locator to reveal these faults The fibers are connected to the wrong ports on the tester or are swapped at one end of the cabling continued Diagnosing Fiber Cabling Faults 8 Diagnosing Failures Table 8 2 Diagnosing Fiber Test Failures cont Loss is negative The fiber ends were dirty during referencing The connections to the tester were disturbed after referencing There was a kink in a reference reference test cord during referencing The connectors were not properly aligned during referencing The testers were much colder during referencing than during testing Some other problem caused a bad reference value If loss is negative set the reference again and retest the cabling See Chapter 6 A known length of cable measures too long or too short e The wrong fiber type is selected on the Fiber Setup menu e The index of refraction needs adjustment Change n on the Fiber Setup menu continued 8 3 DTX Series Cable Analyzer Technical Reference Handbook

100. dB lower worse than worst case ACR results ELFEXT Equal Level Far End Crosstalk Test While NEXT is measured at the same end as the signal source FEXT far end crosstalk is measured at the far end Because all far end crosstalk signals travel the same distance they experience the same amount of attenuation as shown in Figure 3 20 This means that all crosstalk signals contribute equally to noise at the far end This is different from near end crosstalk At the near end crosstalk occurring closer to the source contributes more to noise than crosstalk occurring farther from the source Figure 3 14 Because of attenuation FEXT on longer cables is less than FEXT on shorter cables of the same type Subtracting the effects of attenuation normalizes the results for length and produces ELFEXT equal level far end crosstalk values Since ELFEXT does not depend on length it is used instead of FEXT to evaluate cable performance Because all far end crosstalk signals travel the same distance they tend to add up in phase Therefore high ELFEXT is critical when two or more wire pairs carry signals in the same direction 1000BASE T carries bi directional signals on all four wire pairs so ELFEXT is a critical parameter for 1000BASE T certification Like ACR ELFEXT represents a signal to noise ratio for the cabling Higher ELFEXT values mean that data signals received at the far end of the cabling are much larger than crosstalk signal
