Randomization of Optical Cable Engineering Testing
Randomization is not necessary for most applications involving human interaction. The brain cannot discern different intensity values when so much energy is present.

The power loss in optical power meter testing is too high
Compare your readings to the expected power range, typically around -3 dBm to -10 dBm for single-mode fibers; a sudden drop may indicate excessive loss or damage. Cross-checking with another OPM can confirm if the issue lies with the fiber or the meter. 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. While some loss is expected, excessive or unexpected loss can lead to poor performance, network.
