   Quality part 2
Fiber core fractures and the presence of contamination on ferrules, alignment sleeves or dust caps cause wide variations in both insertion loss and return loss performance.
Surface defects and cleanliness are critical, but will not always be detected with IL or end face geometry testing. A smooth but fractured fiber will not necessarily fail end face geometry checks for radius of curvature, apex offset and fiber height.
End face inspection examples: Contamination (1), Debris (2), Liquid Residue (3) and Adhesive Region Failure (4).
Mechanical reliability parameters include Flex, Torsion and Pull Testing, Cable Retention, Impact Testing, Vibration Testing, Durability and Transmission with an Applied Load.
These mechanical tests verify that a fiber jumper can endure the installation and maintenance performed in a typical fiber optic network, and that they can dependably withstand the internal stresses imposed by spring loaded physical contact over time under in a variety of environmental conditions.
Figure 5 shows fiber break after 50N axial pull for 60s. Figure 6 shows connector deformation after 20N for 60s at 90º pull.
