Effect of Optical Fiber Coating Abrasion on Aging Behavior
Optical fiber can suffer a world of indignities in specialty applications designed to reach beyond the everyday. Consider just a few examples from aggressive, short-term installation conditions to harsh, long-term application environments:
Geophysical fiber is threaded down stainless steel tubing for deployment in oil wells.
Automotive fiber is pulled through the chassis of an automobile on an assembly line only to endure a lifetime of cyclical flexure, road- and engine-vibration, as well as the high temperatures that regularly or seasonally occur in certain parts of the automobile, such as the engine compartment or roof.
- Structural sensing fiber is embedded in concrete, asphalt,
and other building materials so that it can monitor stress
and/or failure.
- Blown fibers are deployed into conduits with highly
pressurized air.
- Military fibers endure high stress and vibration during their
in-service period.
Applying coatings is one way we seek to minimize damage to the fibers, which logically occurs from these real-world treatments. Our new white paper, Effect of Optical Fiber Coating Abrasion on Aging Behavior, shows experimental results of testing performed to replicate installation and application conditions as closely as possible. Initial results show very little change in the strength of fibers coated with acrylate or polyimide after abrasion. Additional experiments are planned.
