Here are some factors that affect the lifespan of fiber optic delay lines:
1. Length: Generally, the longer the fiber optic delay line, the shorter its lifespan.
2. Temperature: The temperature at which the fiber optic delay line is used also affects its lifespan. Excessively high or low temperatures will shorten the lifespan of the fiber optic cable.
3. Humidity: Both excessively high and low humidity environments will reduce the lifespan of the fiber optic delay line.
4. Bending Radius: A bending radius that is too small will also affect the lifespan of the fiber optic delay line.
5. Mechanical Stress: Fiber optic delay lines may be subjected to mechanical stress during use, such as vibration and expansion/contraction. These factors will also affect the lifespan of the fiber optic cable.
