40G Certifier Link Validation

Knowledge Base - Solution

What is the Link Validation limit under the fiber limits on the Viavi 40G Certifier?
Link Validation is an alternative limit selection to TIA or ISO. Link Validation allows the user enter a simple dB value, per wavelength, for the pass/fail analysis. It is also possible to enter a length setting for pass/fail on fiber length. NOTE: Most users do not require a pass/fail on length. The value entered for length is applied to ALL limits including TIA & ISO which is why the default setting is high.
