INTRODUCTION
1.1.INTRODUCTION
The demand for a high end fusion splicer to be used forthe manufacturing of the optical communication equipment and the fiber laser products has been increasing
every year. The high end fusion splicer S183PMII, which
we have sold so far, was a universal type that is capableof splicing the polarization maintaining fiber and the large
core diameter fiber and also capable of making the highstrength fusion splice, but it has been reported that “It istoo difficult to operate because it is too universal.”, “Sizeof the equipment is too large.” etc. Therefore, we havedeveloped the series S185HS / S185PM / S185LDF, inwhich the fusion splice function is limited and the equipment size is greatly reduced. S185HS is a fusion splicer
for high strength fusion splice, S185PM is a fusion splicer
for the polarization maintaining fiber splice and S185LDF
is a fusion splicer for the large core diameter fiber splice.

FEATURES
2.2. FEATURES
2.1 Compact SizeFigure 1 shows the appearance of the S185PM.
Compared with the conventional model S183PMII, themain body has achieved a reduction of 50% by volume
and 40% by weight and also, the AC adapter hasachieved a reduction of 40% by volume. The portability
has been greatly improved and the equipment can beused under various situations because the battery drive(option) became available in addition to the compact size
and the light weight.
2.2 The Improvement of the Fusion Splice
Performance
The resolution of the centering mechanism used for thealignment of the optical fiber has been improved threetimes in comparison to the conventional model and more
precise axis alignment has become possible. Moreover,
the resolution of the optical fiber rotating mechanism necessary for the alignment of the polarization maintaining
fiber is also doubled in comparison to the conventionalmodel and the rotatable range is also possible up to360°, as compared to the conventional 270°. Therefore, aprecise and speedy rotational alignment can be performed.
2.3 The Improvement of the Manual Fusion Splice
For optical fibers that are difficult to splice using theimage processing, the manual fusion splice function isused. But in the new product, a touch panel is adopted
and the optical fiber can be actually moved by touching
the arrow indicating the movable direction of the opticalfiber. The optical fiber can move forward and backward
without switching operation and if you touch the arrow fora short time, the fiber moves one step and if you touch it
for a long time, the fiber moves continuously while touching it. (Figure 2)

2.4The Improvement of the Discharge Control
MethodIn the conventional model, it was necessary to switch thedischarge mode to High / Normal in order to obtain theresolution of the discharge intensity and there was a difficult problem to understand the discharge intensity duplicated in each mode. In the new product, the resolution
was improved 4 times and made switching of the discharge mode unnecessary.
2.5 The Control by the Smartphone Application
With the PC control application (Splice Data Explorer 2),
the screen display and the operation, the reading of thesplicing history data, the setting of the fusion splice andthe heating conditions and the updating the firmware ofthe fusion splicer can be performed easily. (Figure 3)

Figure 3 PC control application: Splice Data Explorer 2.

By installing a Wi-Fi adapter in the fusion splicer, thesame operation as the PC control application can be performed from a dedicated application of the smartphone(Android / iPhone). The fusion splice / heating conditions
can be sent to another user via e-mail or SNS by using
the application. If the fusion splice cannot be performed
normally, you can also easily transmit the various measured values and optical fiber images. (Figure 4)

We made the body compact and lightweight by dedicating to a single function and succeeded in developing thehigh end fusion splicer of the S185 series in which thefusion splice performance was improved by improving theresolution of the alignment, the rotation and the discharge.
We will address the splice of the special optical fiber,
which new products are becoming available one after
another, by upgrading the firmware and the smartphone
application.
