About the Reference for Fiber Tests

The reference procedure for fiber cable sets a baseline power
level for loss measurements. If the power level that enters the
fiber from the source changes, the reference and your loss
measurements will be incorrect. The power level can change, for
example, when the temperature at the job site increases or
decreases or when you disconnect then reconnect a test reference
cord at the tester's output port. So, it is important to set the
reference frequently.
