An optical module's actual transmit power measured by an optical power meter is lower than the nominal transmit power of the power module. The possible causes are: Bores of the optical module are contaminated. Stable optical power is the foundation of every high-capacity optical transport system. 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. This is the domain of Cell-to-Module (CTM) power loss, a series of.
