To avoid the severe nonlinear effects that can reduce conversion efficiency when coupling intense pump light into the extremely thin core, long lengths of fiber are sometimes used to maximize pump light absorption and prevent any residual light on either side of the grating. When utilizing long lengths of fiber, they are typically wound around a specific structure, requiring precise control of the winding tension and density, minimizing space requirements, and facilitating maintenance.

The bending radius of the optical fiber winding boss is 40-50 mm.

[0007] Furthermore: the bending radius of the optical fiber winding boss is 40 mm.
