cabling?td=products#Copper_Certification_and_Testing Line Testers and Cable Certifiers 1.Explain that to certify the cabling structure, a cabling company must measure and warrant the performance of the entire cabling system. 2.Explain the differences between continuity testers and performance testers. Outline some of the things a performance tester can be used to measure. 3.Explain TDR (time domain reflectometer). 4.Describe fiber-optic continuity testers. 5.Explain the functionality of OTDRs (optical time domain reflectometers). 6.Note the expense of cable performance testers. 7.Use Figure 5-51 to illustrate a cable performance tester. OPM (Optical Power Meter) 1.Discuss how an OPM can be used to measure the amount of light power transmitted on a fiber-optic line.
