Probable cause that fiber optic connectors appear contamination

General after fiber cleaver cutting, the cutting angle is typically 1-3 degrees, the use of precision fiber cleaver. Through the above description, it is easy to see non-polished fiber optic splice site for the splicing process and technique sensitive, the key of non-polish field termination technology is still the installer must keep the general cutting and termination processes, and to make the installation process controlled and avoiding rework, always in connection by detecting (such as visible light detection) in order to establish confidence in the termination process, domestic fiber optic can reduce the risks of connection failure .

Causes may lead to splice failures generally include:

First:contamination

Second: fiber splinters

Third: bad cut or broken fibers and so on.

First, probable causes that fiber optic connectors appear contamination are as following:

1. The use of contaminated cutting tool (clean the tool surface by wiping ethanol)

2. After cutting, clean the optical fiber again

3. Placed the connectors or optical fiber in a dusty surface

4. In a dusty environment

5. The insertion of broken fiber, excessive force

Note that once pollution has been brought to the internal fiber optic connectors, and especially after joining hydrogel contact, will be very difficult to be cleared out, this also means that the optical fiber connector is scrapped.

Second, probable reasons that the optical fiber may result in fragmentation:

1.The optical fiber insertion force debris contaminated overproduction

Insert broken fiber caused by fragmentation

3.The embedded fiber debris will cause cracks and fiber optics faults, and the embedded fiber is difficult to be cleared of debris out, in this case an optical fiber connector will be scrapped.

Third, the cause of the fiber cut bad or broken are:

1.Blunt or rip cutting blade – can not properly cut fiber

2.The cutting tool ruler bent tongue on the fiber applied to the excessive concentration of bending force

3.The optical fiber is bent too much or too tight bending radius

4.There is no force in the cutting or insufficient force

5.When the absence of debris or no contamination case, this failure to allow fiber optic connectors are re-cut the connection again.
