How to Generate a Baseline Trace Using Fiber Rings
1.Use the Fiber Ring as a launch cable.
Connect the Fiber Ring between your OTDR and the fiber link under test. This will allow you
to measure the loss of the near-end connection.
2.Use the Fiber Ring as a receive cable.
Cconnect the Fiber Ring to the far-end connector of your fiber link under test. This will
allow you measure the loss of the far-end connection.
3.By using Fiber Rings as both launch and receive cables, as shown in the diagram below,
you can measure total insertion loss of the fiber link under test.
