Figure 5-3. Testing a Connector.
Performing a Connector Test
Use the following procedures to perform return loss tests on a jumper cable connector. When testing
in the [ORL] mode, the display is live. The TURBOTEST 500B is continuously measuring return loss,
thus fiber movement will result in fluctuations in the displayed measurement values. Refer to Figure
5-3 for a related illustration.
1 Attach the APC connector on the reference cable to the Test Port.
2 Attach an adapter to the UPC connector on the reference cable.
3 Attach the jumper cable to be tested to the adapter.
4 Terminate the jumper cable after the adapter by slowly wrapping it around the supplied mandrel until
the back-reflectance reading no longer changes. In most cases 10 wraps are sufficient.
5 The TURBOTEST 500B will automatically measure and display return loss of the connection.
Note
: If you do not want to wrap the jumper cable around the mandrel, attach a Terminator to the
end of the cable to eliminate back reflections.
6 Press the [SAVE] soft key to store test results in the next available memory location.
7 If you need to save test results a specific memory location, perform the following steps:
• Press either [UP] or[ DOWN] arrow key to select a specific memory location (increase or decrease
fiber number).
• Press the [SAVE] soft key to store the test data in the selected location.
8 Unwrap the jumper cable from the mandrel, then disconnect the jumper cable from the adapter.
Attach the opposite end of the jumper cable to the adapter and perform steps 1-7 again to complete
the jumper cable test.
Saved test results can later be retrieved (refer to section titled “Reviewing Saved ORL Test Results”,
page 38).
