Figure 9: Correlation of measured output voltage to signal quality

Note: 

For a measured value to be valid, it is necessary that the partner OZD 

Profi 12M ... on the other end of the optical fiber transmits regular PROFIBUS 
telegrams. An OZD Profi 12M ... is no substitute for a calibrated, optical level 
meter. However, it provides each optical port with a voltage derived from the 
peak value of the optical PROFIBUS telegram without disrupting the 
communication of data. With regular bus operation, this analog voltage can 
be used as an indicator for an alteration in optical attenuation. Because data 
traffic and temperature can affect the voltage value, you should not set any 
warning threshold too close to the actual value.
