Microbends of Fibers | previous | next | feedback |
Definition: microscopic bends of optical fibers
Microbends are microscopic bends of an optical fiber, which can cause bend losses even when the fiber is macroscopically kept straight. Also, they influence the polarization mode dispersion.
Microbends largely arise not during the process of pulling the fiber from the preform, but when the fiber is cabled or spooled. Of course, the amount of microbends strongly depends on the used cabling or spooling technology. For modern telecom fibers, microbends are carefully minimized.
