When the project is finished, the installer should present the project manager a book or flash drive of test results along with a summary in the documentation package on the cable plant. The manager must review the data and decide if the installation was done properly. Do you know how to analyze the data and make that decision?

3. Insertion loss data taken with an optical loss test set or light source and power meter should be compared to ______ to confirm if the fiber passes testing.
A. TIA standards
B. Test equipment “pass/fail” criteria
