Factors Affecting Continuation Loss of Fusion Splicer

What factors will affect the fusion splicer fiber connection loss?

1.Face separation
The connection of the active connector is not good, it is easy to produce the end of the separation, resulting in greater loss of connection. When the fusion splicer discharge voltage is low, it is also easy to produce the end of the separation, this situation is generally in the tensile testing function of the fusion splicer can be found.

2.The quality of the end face
Fiber surface flatness difference will also produce loss, and even bubbles.

3.Near the point of fiber physical deformation
Cable in the erection process of the tensile deformation, then the box in the clamping cable pressure is too large, will have an impact on the loss of the connection, or even several times can not improve the welding.fiber

4.The axis of tilt
When the fiber section tilted 1 °, about 0.6dB of connection loss, if the required loss ≤ 0.1dB, the single-mode fiber inclination should be ≤ 0.3 °.

5.The axis of dislocation
Single-mode fiber core is very thin, two docked fiber axis misalignment will affect the connection loss. When the dislocation of 1.2μm, the connection loss of 0.5dB.
