Techwin China Vital Processes of Evaluating the Splices Do you use a high quality fiber optics splicer for fusion splicing (joining two optical fibers endend to-end end with the use of heat)? If the answer is yes, then you must definitely be aware about the process of fiber splicing. But are you aware about the ideal ways to evaluate the splices? Well, if you wish to know the best method of splices evaluation, read on.
How to Evaluate the Splices? The splices can be evaluated via the following procedure:
Good Splices With the use of both X and Y views, you need to first visually inspect the fibre splicer after running the program. There are some flaws which do not affect optical transmission; thus these flaws are acceptable. Some fibers, like titanium coated or fluorine fluorine-doped may ay result in black or white lines in the splice region. But these are not considered as faults.
Bad Splices As mentioned above, there may be some flaws which are acceptable. But there are other flaws as well which are not acceptable and require you to sta start rt the process of splicing all over again. Some flaws like lines or black spots can be improved via repeating a step, but it can be done more than twice. For larger core offsets, like bulging splices, thick black shadow, thick black line or bubbles you need d to restart the process.
Troubleshooting Splice Issues Following are some of the common splicing problems and their likely causes:
Inclusion or Bubble The causes are as follows:
Time too low or prefusion current Fusion current extremely high Poor cleave Contaminated fiber end faces
Enlargement
Incorrect current Extremely fast autofeed
Constriction
Contaminated electrodes Too wide gap Extremely high prefusion current Extremely long prefusion time Excessively slow feed rate Exceptionally high current
Matchheads
Very high gap Extremely small autofeed Exceptionally high prefusion current Excessively high fusion current Very long prefusion time Contaminated electrodes
Not Fused Through
Very short prefusion time Extremely low prefusion current
With the help of the aforementioned ways, you can effective evaluate the splices. If you discover that the splice is bad or you find any of the above mentioned issue in the splice, you can effectively try again. Now you will not face any issue operating the fiber optics splicer and can conveniently use it to fuse two splices end-to-end.
