EN3745-510 specifies the method for testing aerospace fiber optic cables under sinusoidal vibration conditions. Cable specimens are mounted on a vibration fixture and subjected to controlled vibration profiles across specified frequency ranges and acceleration levels.
During vibration, optical transmission properties are monitored to detect any changes in attenuation or signal interruption. After testing, specimens are evaluated for physical damage and permanent changes in optical performance.
This test simulates the vibration environment experienced by fiber optic cables in aircraft, ensuring that optical connections remain stable and that cables and their terminations can withstand the mechanical stress of in-flight vibration.
