A form of increased attenuation caused by either having the fiber curved around a restrictive radius of curvature, or microbends caused by minute distortions in the fiber imposed by externally induced perturbations. Excessive bend loss may result from poor drawing or cable manufacturing techniques.
A form of increased attenuation in a fiber that results from bending a fiber around a restrictive curvature (a macrobend) or from minute distortions in the fiber (microbend).
Attenuation to an optical signal that occurs when an optical fibre is bent around a tight radius. Light effectively ‘spills out' from the core and is lost in the cladding.
A form of increased attenuation in a fibre that results from bending a fibre around a restrictive curvature (a macrobend) or from minute distortions in the fibre (microbends).
A form of increased attenuation caused by (a) having an optical fiber curved around a restrictive radius of curvature or (b) microbends caused by minute distortions in the fiber imposed by externally induced perturbations.
