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).
