Optical fiber Quality Control

High bit rates and narrow channel spacing require optical fibers with perfect uniformity along the manufactured length.

Optical fiber quality control The use of dense WDM systems has been strongly stimulated by the rapidly growing bandwidth requirements of internet and multimedia communication.
Quality control of fiber coils for gyroscopes, metrology, and dispersion compensation requires precise and individual component qualification and testing in order to validate demanding requirements in terms of strain characteristics.

Optical Fiber Quality Control - monitoring approach

Quality control of fiber optic coils for gyroscopes and dispersion compensation requires precise individual component qualification and testing using distributed fiber optic strain analyzer.

The long lifetime requirement of fiber optic cables can be met only with strain-free fibers. The validation of strain-free conditions requires the measurement of residual fiber strain during and after cable installation which cannot be done with traditional OTDR. Furthermore, the development of high bit rate network requires low polarization mode dispersion (PMD) to achieve rated transmission bit rate. It is recognized that local fiber strain has a direct impact on the increase of PMD valued and performance degradation.
