WebKhalifa University. I think that non-sequential mode is more accurate which allows the ray to be launched and then hit whatever object is in its path. As a result, the ray may be reflected ... WebBelow is the general asphere equation where z is the surface sag, x is the distance from the center, k is the conic constant, R is the base radius, and A# is the polynomial expansion terms. The constantly changing curvature of the aspheric surface allows the optic to correct aberrations in the optical system more efficiently than spherical lenses.

Your OSS should have the ability to assign this factor as an attribute of each cable in your network and then consider it when tracing a route. So assuming a helix factor of 2%, and a break at 34 ... remote south dfw
