☆ Notice: 1> Please do not press “HEAT” after you press “RUN” and when machine in status of

auto splice, otherwise will have error.

2>Fusion splicer will estimate loss one time only after splicing automatically.

3> Only the electrode is well, arc parameter is optimized, fiber character is

identical, then fusion loss is of reference.

4> Best to arc test before splicing.

6.3.5 Splicing partial core fiber If loss is unsteady during splicing, the measures are as follows:

1> Check whether the arc is steady and whether the parameter is proper. 2> If opposite position is steady and the parameter is proper, maybe fiber’s core

is partial. The solution is minish the value of “fusion time” and “fusion push”.

3> If method<2> is useless, to obtain best loss, you must mark direction angle on the

fiber to test fiber’s fusion.

6.3.6 Evaluating fusion quality

Fusion quality is judged by estimating loss, fusion shape and fusion process. Only combine them together, and then the evaluation is external.

1> If fusion process is steady and the spliced fiber’s shape as follows as Table 3,

then the fusion status is well.

c> After confirming, press “ENT” to save arc parameter. d> Press “MENU” to exit menu in turn.

10> Select two pieces of fiber to be spliced and make end-surface. 11> Raise the windshield and the fiber holder in turn. 12>Load two pieces of fiber into worktable and close windshield. 13>Press “TEST” in auto working mode, XL-FS25A will check the quality of fiber’s end-

surface, gap, calibrate cursorily, arc automatically, and then correct value of arc current.

14>If “Too large fusion current” or “Too small fusion current” is displayed on the screen,

please repeat step 10~13 until “Right fusion current” is displayed. So test is finished, and arc program will be rectified to be arc program No.6.

Notice:

1) The selected fiber must be accord with actual fiber. Best to arc test before splicing.

2) Arc test will correct arc position and arc current, so it is normal if gap position changed after test.

3) During the process of arc test, if “Proper fusion current” is not be displayed on screen, please do not enter the parameter menu of the arc program.

4) During the process of arc test, if “Right fusion current” doesn’t be displayed, to avoid useless current, do not enter splice program parameter menu.

5) During the process of arc test, “Right fusion current” has definite range; you can select proper arc current base on actual demand.

6) Arc test is efficient only when electrode is well, so you must check electrode at first. (Consult 6.2.1)

7) The value of “Fusion program” after arc test mustn’t be the best arc parameter due to

consider the factor of “current” only.

8) when pressing "test"button to make splicer arcing for testing,in order to avoid causing errors, don't

press "heat" button.

8.4 Optimization of arc parameter

Those factory-set arc parameters can satisfy splicing of standard fiber basically.

But in order to obtain the best efficiency, it is necessary to optimize arc parameter.

8.4.1 Optimization of SM fiber arc parameter You need some instruments to test fiber’s loss, for example: lamp-house, OTDR.

The process of optimization of arc parameter is same as process of fusion, you

can use instrument to test loss and change arc parameter properly, until loss is of coherence and is the smallest. The general principles of optimization of arc parameter are: 1> Increase of current will get similar effect with extending time in definite range. 2> “Pre-fusion current” mustn’t be bigger than “Fusion current”. 3> Do not modify value of “Fusion push”. 4> Best to change value of “Push speed” after selecting current usually.

Notice:

1> Optimization of arc parameter is effective only when arc electrode is well. 2> Fusion loss displayed on screen is of reference only when arc parameter

is well and spliced fibers’ physical parameter is accordant.

8.4.2 Optimization of MM fiber arc parameter

Optimization of MM fiber arc parameter is different with SM fiber. The relation between selection of MM fiber arc parameter and fusion loss is undemanding. If process of splicing is smooth and splice spot is symmetrical, then loss is satisfied, and you needn’t to test fusion loss. Following are general principles of optimization of arc parameter when splicing MM fiber:

1> The value of “Pre-fusion current” mustn’t be bigger than the value of “Fusion current”. 2> The value of “Pre-fusion time” must bigger than splicing SM fiber.

The possible questions and measures are as follows: 1> There is bubble when splicing.

Solution: Increase value of “Pre-fusion time”, then try to decrease value of “Fusion current” if it is insufficient.

2> Fusion is insufficient and the light string is broken in the center of fiber.

Solution: Increase value of “Fusion time” or decrease value of “Fusion current”.

3> Fiber’s splicing spot becomes smaller.

Solution: Try to decrease value of “Pre-fusion current” or value of “Fusion current”.

Notice: MM fiber fusion program uses special arc mode. It is normal that screen menu shakes or you can hear “pa pa” when splicing.

Operations are as follows:

1) Enter the menu of arc parameter.

2) Increase 1 step size( 10m/s)to the value of “Pre-fusion time”.

3) Splice fiber; increase the value of “Pre-fusion time” until no bubble.

4) Decrease the value of “Pre-fusion current” if no bubble and fiber thins.

13 Addenda B Explanations about arc

It is necessary to select proper arc fusion program if you want to obtain low

fusion loss. Fusion splicer can modify arc current and arc position automatically.

Basic theory: The gap position of fiber’s surface before arc is L0 and L1, The gap position of fiber’s surface after arc is L2 and L3. The formula is as follows:

Δ L = (L3-L2) – (L1-L0)

Base on the value of “ΔL”, you can modify the quality of arc current. The shrinking value of left fiber “ΔL” is gotten from following formula:

ΔL1 = L2 – L0

The shrinking value of right fiber “ΔL” is gotten from following formula:

ΔL2 = L3 – L1 Base on the value of ΔL1 and ΔL2, you can modify gap position to fit the change of arc position.
