FIBER OPTIC CERTIFICATION RESULTS
The SCT Autotest carries out all tests required by industry standards. If a test is not applicable to the selected test standard the test will be
marked ‘informative’ and will not be evaluated for certification.
RESULT SUMMARY
The result summary showing all measurements in summary format is displayed first when viewing results. The result summary display is
formatted for easy viewing of overall result performance displaying all certification result information including each measurement’s worst
case margin and the fiber it occurred on. Result details are available by highlighting the desired result and pressing [ENTER].
RESULT DETAIL
Result detail displays an individual measurement’s detail.
1.
Using the navigation keys select the measurement of interest from the result summary menu and press [ENTER].
The result detail display is formatted for easy viewing of individual measurement result performance, displaying all measurement result
information.
Measurement Results
Loss
Loss results always refer to the fiber connected to the primary unit’s fiber optic adapter input and output connector at the end of a test.
Simplex fiber loss results (non-Bi-Directional)
These loopback mode results are obtained at two wave lengths and measured in one direction on the one fiber.
1.
Loss results are obtained from the input fiber at the end of the test and labeled “Primary Input Fiber”.
The direction of the measurement was from the output connector to the input connector and labeled as “Input
Output”.
Simplex fiber loss results (Bi-Directional)
These loopback mode results are obtained at two wave lengths and measured in two directions on the one fiber.
1.
Both Loss results are obtained from the input fiber at the end of the test and labeled “Primary Input Fiber”.
The direction of the first measurement was from the input connector to the output connector and labeled as “Input >
Output”.
This direction occurs because the fiber was swapped between the first and second test and the results always refer
to the input and output connector at the end of a test.
The direction of the second measurement was from the output connector to the input connector and labeled as “Input
Output”.
Duplex fiber loss results (non-Bi-Directional)
These secondary mode results are obtained at two wave lengths and measured in one direction on each fiber.
1.
Loss results obtained from the input fiber at the end of the test are labeled “Primary Input Fiber”.
The direction of the primary input fiber measurement was from the secondary output connector to the primary input
connector and labeled as “Pri
2.
Loss results obtained from the output fiber at the end of the test are labeled “Primary Output Fiber”.
The direction of the primary output fiber measurement was from the primary output connector to the secondary input
connector and labeled as “Pri > Sec”.
Duplex fiber loss results (Bi-Directional)
These secondary mode results are obtained at two wave lengths and measured in two directions on each fiber.
1.
Loss results obtained from the input fiber at the end of the test are labeled “Primary Input Fiber”.
The direction of the first primary input fiber measurement was from the primary output connector to the secondary input
connector and labeled as “Pri > Sec”.
This direction occurs because the fiber was swapped between the first and second test and the results always refer
to the input and output connector at the end of a test.
The direction of the second primary input fiber measurement was from the secondary output connector to the primary
input connector and labeled as “Pri
2.
Loss results obtained from the output fiber at the end of the test are labeled “Primary Output Fiber”.
The direction of the first primary output fiber measurement was from the secondary output connector to the primary
input connector and labeled as “Pri
The direction of the second primary output fiber measurement was from the primary output connector to the secondary
input connector and labeled as “Pri > Sec”.
This direction occurs because the fiber was swapped between the first and second test and the results always refer
to the input and output connector at the end of a test.
