1: The role of grinding angle on fiber end face
The main function of grinding the fiber, can reduce light reflection and improve return loss. Grinding the fiber into an angle, can guide some of the reflected light into the cladding. thereby reducing the amount of reflected light returning to the fiber core. increasing the return loss, and allowing more light to be transmitted in the fiber.
2: The influence of different grinding angles on return loss
Flat end face: Reflected light to the light source along the original path, with low return loss,40dB.
Angle incline plane: Reflecting light can guide into the cladding, reducing the amount of reflected light returning to the fiber core. The return loss is relatively high, usually -65dB.
Physical contact: The end face is slightly spherical, with a return loss of -40dB.
Superphysical End Face: The end face has a slight curvature and a return loss of -55dB.
Slope Physical Contact: The end face is ground to an angle, resulting in the highest return loss of -65dB.
3: Structure and transmission principle of fiber optic end face.
Fiber optic cables consist of a core, cladding, and coating, and the propagation of light in the fiber relies on the principle of total optical reflection. The refractive index of the fiber core and cladding is different. When light enters the fiber at a specific angle, it undergoes total reflection between the core and cladding, thus propagating in the fiber.
