As MINI3S is designed for fusion splicing silica glass optical bers, it is very
important that the splicer should not be used for any other purposes. The splicer is
a precision instrument and must be handled with caution. Therefore, you must read
the following safety rules and general precautions in this manual regarding the use
and handling of MINI3S at any time. Any behaviors that do not follow the warnings
and cautions will break the safety standard about design, manufacture, and usage
of the fusion splicer. The users will be liable for any consequences incurred from
violation of the related requirements!
① Never operate the splicer in an environment where flammable liquids or vapors
exist.
② DO NOT touch the electrodes when the splicer is on.
Note: Only use specied electrodes for the fusion splicer. Select [Replace electrode]
in maintenance menu to replace electrodes, or turn o the splicer and disconnect
the AC power source or remove battery before replacing electrodes. Discharging is
prohibited before the electrodes are placed as a pair.
③ DO NOT disassemble or modify any components of the splicer without approval,
except for the permitted-to-disassemble / modify components or parts by users
stated in this manual. Component replacement and its internal adjustment must be
implemented by authorized technicians or engineers.
④ Handle the main supply cable carefully. Pull out the cable from the electrical
socket by holding only the wall plug and not by pulling the cable. Always ensure this
cable to be in good condition. Otherwise, there is a risk of re or electrical shock.
⑤ To prevent any re or electrical shock, do not expose the splicer to rain or damp
conditions.
⑥ Safety glasses should always be worn during ber preparation and splicing
operation. Fiber fragments can be extremely dangerous if they come into contact
with the eye, skin, or are ingested.

depending on its viewing angles. Note that these symptoms are not defects, but are
natural phenomenon.
3.6 Preparing the Fiber
3 steps should be carried out before splicing:.
1.Stripping
Remove at least 50mm of secondary coating (valid for both tight and loose tube
secondary coating) and approximately 30~40mm of primary coating with an
appropriate stripper.
Note: always remember to slip a
heat-shrinkable sleeve onto either
end of the bers at the beginning
of each ber preparations.
2. Clean bare bers with pure alcohol-soaked gauze or lint-free tissue.
3. Cleave the ber
In order to ensure the best splicing result, cleave the bers with high quality cleaver
such as DC-09 ber cleaver, and strictly control the cleaving lengths shown as
below.
Important!
From this moment, you must be very careful with the bers to ensure that they do
not become dirty again.(For example, avoid putting them down on a dusty working
surface, or even waving them around in the air). Also check if the V-grooves are
clean, if not, wipe them clean.
3.3 Turn On the Splicer
Press [Power] key on the operation
panel, and wait the splicer to be
turned on and move to Workbench
page.

② Open the ber holder. Position
the bers into V-grooves. Make
sure the ber ends are between
the V-groove edges and the
electrode tip.
Note: Make sure to avoid sliding the
bers along V-grooves, but rather
position them over V-grooves and tilt
them down into place (as shown in the
picture).
③ Close the ber holder.
④ Close the wind proof cover
3.8 Inspecting the Fibers

Chapter 4 Splice Mode
4.1 Displaying the Active Splice Program
MINI3S has an intuitive and simple but very powerful program structure to operate.
Splice programs dene arc currents, splice times as well as various parameters
used when performing a splice. Therefore, it is essential to select the correct splice
program.
There are a number of “Preset” splice programs for common ber combinations.
Therefore, it is much easier to modify and further optimize the parameters for more
unusual ber combinations.
The active splice program is
always displayed at the top of the
screen (see below).
4.2 Selecting a Splice Program
To select another splice program
other than the active one, you
must enter Select splice mode
menu.
① Enter main menu
② Select Splice Mode
③ Highlight the program you
want to select.
④ Back to initial interface
4.3 General Splicing Steps
This section explains the steps involved in automatic splicing process and describes
how various program parameters are related to this process. The normal splicing
process can be divided into two sections: pre-fusion and fusion.
Pre-Fusion
During pre-fusion, the splicer performs automatic alignment and focusing, where
the bers are subjected to a low pre-fusion current for cleaning purposes; a pre-
fusion image is also taken. At this point, the user is informed of any problems
recognized in the pre-fusion image, such as a poorly prepared ber. The splicer will
then issue a warning before the bers are fused together.

2322
Fusion
Splicing Process
During fusion, the bers are joined together and subjected to ve dierent currents
as illustrated below. An important parameter, which changes during splicing, is
the distance between the bers. During Pre-fusion, the bers are apart. With the
current phase changing, bers are spliced gradually.
The most important splicing parameters are the time and current, each current
phase is shown below, that the name and function and other parameters are
important to the splice process are described under “Parameters for Normal
Splicing Process” on the next page.
The following gure shows the discharge conditions (The relationship between the
“discharge intensity" and "motor move"). We can change the splicing parameters
listed below to change the discharge conditions.
A: Pre-fuse power B: Arc power C: Cleaning Arc
D: Pre-fuse time E: Arc time F: Overlap
G: Taper wait time H: Taper time related to taper length I: Taper speed

4.4 Parameters for Normal Splicing Process
Parameter Description
Template
A list of splice modes stored in the splicer database is displayed.
Upon inputting the appropriate mode, the selected splice mode
stored in database area is copied to a selected splice mode in user-
programmable area.
Name Title for a splice mode expressed in up to seven characters.
Note Detailed explanation for a splice mode expressed in up to 15
characters. It is displayed at “Select splice mode” menu.
Focus-L Set the focus parameter for lens X.
Focus-R Set the focus parameter for lens Y.
Arc adjust Set to adjust arc power according to the bers’ conditions.
Pull test If “Proof test” is set to “ON”, a pull-test is performed upon opening
the windproof cover or by pressing the SET button after splicing.
Loss
estimate
Loss estimate should be regarded as a reference. Since the loss is
calculated upon the ber image, there is certain dierence with the
real value. The estimate method is based on a single mode ber and
calculates at the wavelength of 1.31μm. The estimated value can be a
valuable reference, but cannot be used as the basis of acceptance.
Minimum
loss
This amount is added to the estimate splice loss originally calculated.
When splicing specially or dissimilar bers, a high actual splice loss
may occur even with optimized arc conditions. To make the actual
splice loss concur with the estimated splice loss, set the actual splice
loss to minimum value (minimum loss).
Loss Limit An error message is displayed if the estimated splice loss exceeds
the selected threshold (loss limit).
Core angle
limit
An error message is displayed if the bend angle of the two bers
spliced exceeds the selected threshold (Core angle limit).
Cleave angle
limit
An error message is displayed if the cleave angle of either the left or
right ber ends exceed the selected threshold (cleave limit).
Gap position
Set the relative position of the splicing location to the center of
electrodes. Splice loss may be improved in the case of dissimilar
ber splicing by shifting [Gap position] towards a ber whose MFD is
bigger than the other ber MFD.
Gap Set the end-face gap between the left and right bers at the time of
aligning and pre-fusion discharge.

Chapter 5 Splice Option
As to the Splice Mode setting.
① Select [Splice option] in menu from
main menu.
② Select a parameter to be changed.
Parameter Description
Auto start
If “Auto start” is set to ON, splicing starts automatically as soon as
the wind protector is closed. Fibers should be prepared and placed
into the splicer in advance.
Pause 1
If “Pause 1” is set to ON, splicing operation pauses when bers are
forwarded to gap-set position. Cleave angles are displayed during
the pause.
Pause 2 If “Pause 2” is set to ON, splicing operation pauses after ber
alignment is completed.
Realign after
pause 2
Alignment failure may appear after “Pause2” for a long period.
Therefore, realign after “Pause2” is needed. Setting to “OFF” will
prevent the implementation of realign function. Manual splicing,
rather than setting the realign to “OFF”, is recommended when there
is an axial displacement of the splicer

Set the overlap amount of bers at the ber propelling stage.
Relatively small [Overlap] is recommended if [Preheat Arc Value] is
low, while relatively large [Overlap] is recommended if [Preheat Arc
Value] is high.
Cleaning Arc
time
A cleaning arc burns out micro dust on the surface of the ber with
an arc discharge for a short period of time. The duration of the
cleaning arc can be changed by this parameter.
Preheat Arc
value
Set the pre-fuse arc power from the beginning of arc discharging
to the beginning of bers propelling. If “Preheat Arc Value” is set
too low, axial oset may occur if cleaved angles are relatively poor.
If “Preheat Arc Value” is set too high, ber end faces are fused
excessively and splice loss gets worse.
Preheat Arc

Chapter 7 Maintenance Menu
The splicer has a function to perform routine maintenance. This section describes
how to use the maintenance menu.
① Press Menu button, and select [Maintenance menu].
② Select a function to perform.
7.1 Replace Electrodes
As electrodes are worn out during the splicing process, oxide generated on the tips
of electrodes should be regularly eliminated. It is recommended that the electrodes
should be replaced after 2500 arc discharges. When the number of arc discharges
reaches a count of 2500, a message prompting to replace the electrodes is
displayed immediately after turning on the power. Using the electrodes without a
replacement will result in greater splice loss and reduced splice strength.
Replacement Procedure
① Select [Replace electrodes] in [Maintenance Menu].
② Instruction messages will appear on the screen to turn o the power. Click on OK
until LCD shuts down to continue.
③ Remove the old electrodes.
ⅰ ) Loosen screw located on electrode cover.
ⅱ ) Take electrodes out of the electrode covers. (Electrodes are xed in electrode
cover)
④ Clean the new electrodes with alcohol-impregnated clean gauze or lint-free
tissue, and install them in the splicer.
ⅰ）Insert the electrodes in the electrode covers.
ⅱ）Place the electrode covers on the splicer, and tighten the screws.

7.2 Stabilize Electrodes
In the event of sudden change in environmental conditions, especially when the
splicer is moved from lower altitudes to higher altitudes, the arc power may become
unstable, resulting in higher splice loss. In such case, it takes time for arc power to
be stabilized. In this case, stabilizing electrodes will expedite the process to set the
arc power stable. If many tests are needed until the “Operation Complete” message
appears in [Arc calibration], use this function as well.
Operation Procedure
① Select [Stabilize electrodes].
② Place prepared bers into the splicer for splicing.
③ Press [SET] button, and the splicer will begin to stabilize the electrodes
automatically in the following procedures:
• Repeat arc discharge ve times to measure the arc position.
• Perform splicing rapidly.
•Perform stabilizing electrodes 20 times consecutively to precisely locate the
electrodes position.
7.3 Diagnostic Test
MINI3S has a built-in diagnostic test function that allows the user to evaluate
several critical variable parameters with only one simple step. Perform this function
in case of splicer operation fault.
Operation Procedure
① Select [Diagnostic Test] in [Maintenance Menu]
② Execute [Diagnostic test], then the following checks will be made.
Parameter Description

Through image acquisition, the splicer detects dust and contaminants on the splicer,
camera, and objective lenses that may disturb normal observation of bers and
result in improper splicing. This function checks the optical path for the presence
or absence of contaminants, and judges whether they will aect the quality of ber
splicing.
Operation Procedure
① Select [Dust check] in [Maintenance menu].
② If bers are set in the splicer, remove them and press [SET] again to start the
dust check.
③ If no dust exists, splicer will prompt out message for operation completion. If
dust is detected during the dust check process, the message “Found Dust On The
Lens” will be displayed on screen. Press the return button twice, and the location of
contamination will be shown on the screen. Then clean the objective lenses, and [Dust
check] until the message “Operation Complete” is shown on screen.
Note:
If contamination still exists after cleaning the objective lenses, please contact your
nearest sales agent
7.5 Motor Calibration
Motors are adjusted at the factory before shipping. However, settings may be
changed in various reasons. This function automatically calibrates the speed of 4
motors.
Operation Procedure
① Select “Motor Calibration” in “Maintenance Menu”.
② Load prepared bers in the splicer and press “SET” button.
③ Speeds for all motors are automatically calibrated. Upon completion, message
will be displayed.
Note:
Perform this function when "Fat " or "Thin" error occurs, or ber aligning or focusing
takes too much time.
⑤ We recommend all users to do stabilizing electrodes and arc calibration after
electrodes replacing to keep good splice results and splice strength (Details are
described below).

Operation procedure
① Select [Arc Calibration] in [Maintenance Menu] to display arc calibration on the
screen.
② Place prepared bers into the splicer, and press [SET] to perform arc calibration.
③ The splicer will show up two values on the screen after each arc calibration. If the
value shown on the right-hand side meets 11±2, the message “Operation Complete”
will be shown on screen. Otherwise, set prepared bers on the splicer again and
redo arc calibration until the message “Operation Complete” is displayed.
Note :
* Use standard SM、DS or MM ber for arc calibration.
* Ensure clean bers for arc calibration. Dust on the ber surface aects arc
calibration.
7.7 Electrode Setting
Set the electrode change warnings. We recommend replacing the electrodes every
4500 discharge to ensure the best splice results.
① Select [Electrode Setting] in [Maintenance Menu].
② Set the electrode caution and electrode warning.
7.8 Quick Optimize

out simple operation for adjusting 4 motors’ calibration of fusion splicer.
1 Select quick optimize in maintenance menu.
Parameter Description
Electrode
caution
If actual arc discharge exceeds the set value, a message “Caution!
Replace Electrodes” is displayed when turning on the splicer.
Fiber Fox recommends that this parameter should be set to “2500”
Electrode
warning
If actual arc discharge exceeds the set value, a message “Warning!
Replace Electrodes” is displayed when turning on the splicer.
Fiber Fox recommends that this parameter should be set to “3500”.
Parameter Description
Adjust position Adjust the motor’s position automatically.
Motor calibration Adjust 4 motor speeds automatically.
2 Follows are the optimizing functions in Quick optimize.
7.6 Arc Calibration
Atmospheric conditions such as temperature, humidity and pressure are constantly
changing, which creates variability in the arc temperature. MINI3S is equipped with
temperature and pressure sensors that are used in a constant feedback monitoring
control system to maintain the arc power at a stable level. However, changes in arc
power due to electrode wear and glass adhesion cannot be calibrated automatically.
Also, the center position of arc discharge sometimes shifts to the left or to the
right. In this case, the ber splicing position has to be shifted in relation to the arc
discharge center. It is necessary to perform an arc power calibration to eliminate
those problems.
Note :
* Arc calibration is performed automatically in SM mode only. So, arc calibration
does not have to be performed when splicing in SM mode.
* Performing Arc Calibration function changes the arc power value. The arc power
value is used in the algorithm program for all splicing. The arc power value will not
be changed in the splice modes.
