Fiber optic cable end beveling effect
The 8° angled bevel makes the fiber end face tighter and reflects light through its beveled angle to the cladding instead of returning directly to the source, providing better connection performance. If it is small, light reflected at the output surface (Fresnel reflection due to the index difference to air) will essentially travel backward in the. It can be either protruding (positive fiber height) or recessed (negative fiber height). Inadvertent tight bends are common in high-density installations and in plants which are frequently reconfigured (e. As a result, the connector side can be connected to equipment, while the other side is fused in the case of fusion splicing and a mechanical connection in the case.
