What does it mean if the optical module power is too high
Overloading of optical power, also known as saturated optical power, refers to the maximum allowable optical power that the optical module can withstand without causing signal “explosion” and subsequent data loss. The unit of measurement for overload optical power is dBm. When the optical modules at both ends of the link work normally, the transmit optical power is within a certain range, which can be learned by checking the corresponding product datasheet or reading the module threshold on the switch. If it still does not work, change the module. Even minor deviations—whether too high, too low, or unstable—can impact signal integrity, trigger service alarms, or interrupt traffic on DWDM, OTN, or long-haul optical line systems.

The optical power meter has a positive value after calibration
The magnitude of this error is a function of both wavelength and connector type, and, as a result, the power meter should be calibrated with the same fiber and connector with which it is to be used. This application note demystifies how EXFO's IQS-12002 Optical Calibration System can guide. This reflected energy causes the optical power meter to read higher than it would for a coUimated beam equal in power. NIST developed a testing system to provide absolute power calibrations for optical power meters. Due to the fact that this capability largely depends on the quality of the calibration process, it is important to carefully select your calibration provider.
