Test and verify signal performance is as expected via Link Loss Budget analysis. Remove or add attenuators as
needed to maintain proper power margin.
Upon successful completion of Step # 5, manually switch the Network Element to “Protect” and verify valid switch via
PM (Performance Monitoring) analysis.
Upon successful completion of Step # 6, perform steps 3-5 as above applied to the TX (Working) and RX (Working)
fiber pair.
Upon successful completion of Step # 7 and verification that the “Working” path is properly operating via PM Analy
