How to correctly use optical fiber welding machine

the correct use of optical fiber welding machine is the important guarantee of reduce the loss of fiber connection and the key link, the specific steps are as follows:

1. Should be in strict accordance with the welding machine instructions and operation process, correct operation welding machine.

2。 Reasonable optical fiber placement, place the fiber of V groove welding machine, the movement wants light. This is because the fiber core diameter of 10 nm single-mode fiber, if you want to weld loss less than 0. 1 db, the optical axis of the radial deviation less than 0. 8nm。

3。 Correct reasonably set depending on the type of optical fiber welding parameters ( Pre discharge current, time and andadministrative electric current, andadministrative electric time, etc. ) 。

4。 In the use and after use to remove the dust in the welding machine (timely In particular, when the fixture, the mirror and v groove of dust and fiber pulverized) 。

5。 Welding the service life of mechanical and electrical pole generally about 2000 times, use for a long time after the electrode will be oxidized, lead to loss of discharge current is big and make the weld value increases. At this time to remove the electrode, use medical absorbent cotton dipped in alcohol wiped gently and then to the welding machine, cleaning and discharge at a time. If the discharge current is still large after cleaning for many times, must replace the electrodes.
