    The basics of testing should include all measurements commonly made and the instruments used for making those measurements. This includes continuity checking and tracing, measuring optical power,  insertion loss testing with a power meter and source and using OTDRs. Particular attention should be paid to understanding the methods of testing and the errors inherent in the measurements. The student needs to understand that the loss of the cable plant must be measured with a light source and power meter per industry standards, and OTDR testing is optional.
   Various methods of making the same test should be understood, especially the differences between insertion loss and OTDR testing and the effects of the various methods used in setting the "0 dB" reference in insertion loss testing.
