6481 Series Optical Fiber Fusion Splicer
Quick Guide
This carry-around Quick Guide briefly introduces the basic functions and operating methods of the
instrument. For detailed instructions, please read the User Manual.
Before using this product, be sure to read this guide carefully, and remember to keep this guide properly
while carrying it around, so as to use and maintain this product properly by reading the guide at any time.
If the altitude is higher or the temperature changes a lot, the discharge correction shall be performed
before fusion. Discharge correction is used to optimize the discharge arc position and current size
according to the following steps:
1. Place a standard single-mode fiber with well-prepared cross-section into the fusion splicer.
2. In the menu, select [Maintenance] → [Discharge] → [Discharge Correction] and press [Enter] button
to start the discharge correction.
3. Fusion splicer automatically discharge, correct the arc position and adjust current size. If the
calibration is not successful, replace the two test fibers with the well-finished cross-sections
according to the instructions, and perform another discharge arc calibration.

Preparation of Fiber
1. First fit the fiber into the heat-shrink
tube.
2. Strip off the fiber and make sure that
the coating residue on the stripped
fiber has been removed.
3. Clean the fiber with anhydrous
ethanol at a concentration of 99% or
more.
4. Cut the fiber at the correct cutting
length.
Fusion fiber
1. Place the fiber on the fusion splicer
and make sure that the fiber is on the
bottom of V-groove and the fiber end
is placed between the edge of
V-groove and the center of electrode.
2. Check the fusion and heating modes.
In case of the fusion for the standard
single-mode fiber (ITU-T G.652),
"SM-SM" mode shall be selected.
3. Close the windshield and start fusion.
4. Observe the fusion process through
the monitor.
Heat-shrink protection
1. Take out the finished fiber.
2. Place the heat-shrink tube at the
middle of heater and move the fiber so
that the fusion point is at the center of
heat-shrink tube.
3. Close the heater cover and start
heating.
4. After heat shrink is completed, take out
the heat-shrink tube. If the heat-shrink
effect is poor, the heating time may be
modified accordingly (in the heating
mode menu).

 Cleaning of V-groove
The dirt on V-groove or fiber fixture may cause the fibers to deflect, resulting in larger fusion loss.
1. Prepare a fiber and cut about 10mm from the bottom.
2. Keep the fiber at a 45°angle.
3. Clean the contaminants in V-groove by pushing it with the end of a well-cut fiber along the one
direction.
4. If V-groove is too dirty, clean the contents in V-groove with a pointed cotton swab, and clean the
bottom of V-groove along one direction with a fine cotton swab moistened with absolute alcohol.
Note: If the left and right images are significantly misaligned after the fiber propulsion, V-groove
must be cleaned.
Cleaning and Maintenance

Cleaning of objective lens
1. Lenses that are contaminated or damaged
may result in high fusion loss or poor
connections. Therefore, both objective lenses
shall be cleaned regularly. Otherwise dust will
accumulate and eventually cannot be
removed.
2. Before cleaning the objective lens, first turn off
the power.
3. Clean the objective lens with a fine cotton
swab moistened with absolute alcohol. Wipe
the lens with a cotton swab from the middle of
lens and along the circular trajectory until the
edge of lens is wiped. Do not touch V-groove.
4. Then wipe off the remaining alcohol with a
clean, dry cotton swab.
Cleaning of fiber presser
1. Windshield is equipped with two fiber pressers that
hold the fiber against V-groove and shall be kept
clean.
2. Open the windshield and clean the fiber presser
with a cotton swab moistened with absolute alcohol.

 Prevent the debris from falling into the instrument
Debris falling inside the fusion splicer may cause malfunction, and the debris
shall be prevented from falling into the red area in the figure below.
 Monitor cover
Monitor cover protects the monitor during the daily operation of fusion splicer.
If it is necessary to remove or install the cover, please proceed as shown
below.
 Maintenance of lithium battery
1. Battery shall be charged once every three months during the long-term
storage.
2. The temperature range for the long-term storage of battery (storage time
over 6 months) is: 0 °C ~ 40 °C. The temperature range for the short-term
storage of battery is: -20°C to 60°C.
Precautions
The polished frame of monitor cover is narrow upper
and wide lower. Pay attention to the correct direction
during installation.
Open from the left when removing the cover.
