In the daily use of welding machines, some friends often say that they have just maintained the machine recently, replaced the electrode rods, and made discharge corrections. Why does the welding loss still not come down?
In fact, this situation is often closely related to the user's own operating techniques. Fusion splicer is a precision instrument that can produce minimal fiber loss under optimal operating conditions. However, the prerequisite is that there is a flat and clean fiber cutting end face, which depends on standardized operating procedures and methods.
Today, we will take a look at the possible causes of fiber optic connection failures, which roughly include:
1、 Pollution;
2、 Fiber optic fragmentation;
3、 Poor cutting of optical fibers.
1、 Possible causes of pollution include:
①. Didn't clean the fiber properly, peeled off the fiber directly by hand
(Use anhydrous alcohol to clean the fiber after stripping)
②. Using contaminated cutting knives
(Use a cotton swab dipped in alcohol to wipe the cutting blade)
③. After cutting, the fiber was wiped again
(Never wipe the fiber after cutting)
④. In a dusty environment
(Why don't you put on a mask?)
2、 Possible reasons for fiber optic fragmentation include:
①. Poor cutting quality directly leads to fragmentation
(Rotate to a new blade face or adjust the blade height)
②. The end face of the optical fiber has touched something else
(After cutting the optical fiber, do not let the end face of the optical fiber connect to any object again)
3、 The reasons for poor fiber cutting include:
①. The optical fiber is not placed perpendicular to the cutting blade surface
(Ensure that the optical fiber is placed in the groove of the cutting tool fixture)
②. The coating layer of the optical fiber is placed on the cutting rubber pad
(Place the optical fiber back a bit, and the part left on the rubber pad should be the part with the coating removed)
③. No force or excessive force during cutting
(Practice more and find the right degree)
