Attenuation

Chapter 3 Optical TAPs

rev. 1

(Number of Connectors * Connector Loss) + (Fiber Length of Link A *

Fiber Loss) + (Fiber Length of Analyzer * Fiber Loss) = Attenuation

6 Subtract the output from step 5 from step 4.

Power Loss Budget - Attenuation = Actual Loss

7 Repeat step 4 through step 6 for Link B to the analyzer.

For example, Figure 8 shows cable lengths to the TAP from the

network devices and from the TAP to the analyzer. Using these cable

lengths and some information from the device manufacturers, you can

determine the power loss.

Figure 8 Cable lengths to/from the TAP

The equations here are examples of how to calculate a power loss

budget with actual values.
