If the user has not timely adopted measures to solve failures of the Optical

Fiber Fusion Splicer in case of meeting these failures, it may cause the

equipment scrap, electric shock, fire or personal injury or even death.

The AC-DC adapter and battery charger of the Optical Fiber Fusion Splicer

can only use an AC power source (100V-240V AC, 50hz-60hz). If the user

uses the improper AC power source, it may possibly lead to smoke, electric

shock, equipment damage, and even cause the fire or personal injury or

death. (Note: Usually, AC generators output abnormal high pressure and

irregular frequency, so that it is necessary to measure generator’s output

voltage value with the ammeter before connecting the AC power cord.

Abnormal high pressure or frequency can lead to smoke, electric shock,

equipment damage, and can even cause fire or personal injury or death.

Make sure the generator’s regular check and maintenance.

MAIN POINTS OF FUSION SPLICING PROCEDURES

1. How to Get Small Splicing Loss

1-1. Necessary Regular Cleaning Jobs

 To Clean V-Shaped Groove

 To Clean Reflecting Mirror

 To Clean Optical Fiber Pressure Head

 To Clean Objective Lenses

In case of cleaning Objective Lens，it is unnecessary to remove

needle electrodes

1-2. Selection/Usage of Appropriate Splicing Modes

Please select the appropriate splicing modes according to different

sorts of the Optical Fibers.

1-3. Equipment Clean-up before Each Fusion Splicing Operation

 To clean the blades of Optical Fiber Stripper.

 To clean the rubber pad and blades of the Optical Fiber Cleaver.

1-4. FUSION SPLICING PROCEDURES

 Make sure that the coating residue and other contaminants on

the optical fiber will have been removed after stripping the optical

fiber.

 Please use the pure alcohol with a concentration of more than

99%.

 Do not let the well-cut end of the optical Fiber touch any object or

be contaminated.

 Please put the end of the optical Fiber at the place between the

edge of the V-shaped groove and the center of electrode.

 Please put the optical Fiber rightly on the bottom of the V-shaped

groove.

 Make sure the correct cut length. If the cut length is too short, the

optical Fiber’s coating edge may possibly encounter the V-

shaped groove, so that two optical fibers can not be, in the

discharge process, fully close to each other, resulting in

undesirable loss of fusion splicing.

 Do not tight the optical fibers, otherwise, two optical fibers can

not be, in the discharge process, fully close to each other,

resulting in undesirable loss of fusion splicing.

 Please check the cutting angle and shape of the optical fiber’s

end face. The optical Fiber’s cutting angle will affect the fusion-

splicing quality, and a large cutting angle will increase the loss of

fusion splicing.

10

 It is possible to observe the discharge from the display screen. If

the discharge "vibration" or "flickering light" are being observed,

the discharge may be unstable at this time and will result in

adverse loss.

 In case of heating, the Optical Fiber heat-shrinkable sleeve shall

be placed in the center of the heater, so as to avoid uneven

heating and lead to additional losses.

2. Power Supply

Please only use the AC-DC Adaptor provided by the manufacturer.

Please only use the Storage Battery and Battery Charger provided by

the manufacturer.

2-1. Avoidance of Damage to AC Adapter

 The AC generators may possibly produce abnormal output of AC

high voltage or irregular frequency.

 The abnormal high voltage and frequency output from the

generator may possibly lead to smoke, electric shocks and

damage to the equipment, and even cause the fire, the personal

injury or death. So, before connecting the AC power supply, you

must use a multimeter to measure the generator output voltage.

2-2. Storage Battery

 Even if the storage battery is not used, its capacity will also

gradually go down along with the time goes, and if it is fully

discharged, it would never be able to charge into the electricity.

So, if it will be stored for a long time or it has been used, please

charge it in time.

 If it is necessary to store a pack of storage battery for a long time,

and no matter how much electricity quantity it has been charged

before, you should charge it every six months.

 For operating/charging/longtime storing the storage battery,

please refer to the conditions as below:

MAINTENANCE OF FUSION SPLICING QUALITY

1. CLEANING AND CHECKING BEFORE FUSION SPLICING

The following describes the maintenance checks for the key cleaning

points and the important parts.

1-1.Cleaning the V-Shaped Groove

If there are dusts or contaminations in the V-shaped groove, the

optical Fiber Pressure Head can not suppress the Optical Fiber

correctly, resulting in that the loss of fusion splicing is larger. So, in

regular operation, it is necessary to check more often and clean

regularly the V-shaped groove.

 To open the windproof cover.

 To clean the bottom of the V-shaped groove with a cotton swab

just having had a dip in alcohol (above 99% alcohol), and remove

the excess alcohol in the V-shaped groove with a dry cotton

14

swab.

 If contaminations in the V-shaped groove can not be removed

with a cotton swab just having had a dip in alcohol, you can use

the well-cut end face of the optical Fiber to clean the bottom of

the V-shaped groove, and then repeat the previous step.

 In case of cleaning the V-shaped groove, be careful and don’t

exert an excessive force, so as to avoid damage to the V-shaped

groove.

 Be careful and don’t touch the tip of the needle electrode.

1-2. Cleaning Up the Optical Fiber Pressure Head

If there are contaminations on the Optical Fiber Pressure Head,

the optical Fiber Pressure Head can not suppress the Optical

Fiber normally, resulting in degrading the quality of fusion splicing.

 To open the windproof cover.

 To clean the surface of the Optical Fiber Pressure Head with a

cotton swab just having had a dip in alcohol (above 99% alcohol),

and remove the excess alcohol on the surface of the Optical

Fiber Pressure Head with a dry cotton swab.

1-3. Cleaning the Optical Fiber Cleaver

If there are contaminations on the blades of the Optical Fiber

Cleaver or the rubber pad, the cleaving quality will be degraded,

and lead to dusts on the surface of the optical Fiber, resulting in

the increase of the loss of the fusion splicing. It is necessary to

clean the blades of the Optical Fiber Cleaver. or the rubber pad

with a cotton swab just having had a dip in alcohol (above 99%

alcohol)

1-4. Discharge Tests

Atmospheric environment, such as: temperature, humidity, air

pressure, is constantly changing, so that the discharge

temperature is also changing. Due to the electrode wear, it is

unable to automatically correct the discharge strength caused by

the bonding of the optical Fiber debris. The center of the discharge

sometimes will move to the left or to the right. At this time, it is

necessary to make the discharge tests to solve these problems.

It is also necessary to do discharge tests in case of using the

Optical Fiber Fusion Splicer under the following conditions: such

as ultra-high temperature, ultra-low temperature, very dry, very

wet, electrode degradation, fusion splicing of the heterogeneous

optical Fibers, cleanness, after replacing the electrode, or in the

case that above conditions exist simultaneously.

15

2. REGULAR CHECKING AND CLEANING

In order to ensure the better splicing quality, it is suggested to check

and clean the Optical Fiber Fusion Splicer regularly.

2-1. Cleaning the Objective Lens

If there are contaminations on the surface of the Objective Lens,

the normal location of the observed optical Fiber core may be

affected, resulting in the increase of the fusion splicing loss or poor

fusing splicing, so, it is necessary to regularly clean two objective

lenses, otherwise, the cumulative contaminations are difficult to

remove.

 Before cleaning, please firstly turn off the power supply.

 Using a cotton swab just having had a dip in alcohol (above 99%

alcohol), to gently wipe the surface of the objective lens, starting

the wipe from the middle of the lens to do a circular movement

until the edge of the lens, and repeating several times until there

are no contaminations or stains or stripes. Finally, use a clean

and dry cotton swab to wipe out the residual alcohol on the

surface of the objective lens.

 Be careful and don’t touch the electrode tip in case of cleaning.

 It is recommended to clean the lens in case of replacing the

needle electrode.

2-2.Replacing the Electrode

The electrode will wear in use, and the electrode tip will be

aggregated with silicon oxide, so, to regularly clean the oxide can

effectively extend the life of the needle electrode. It is

recommended to replace the electrode after Optical Fiber Fusion

Splicer has discharged 3000 times. If you continue to use the

electrode, it may most probably lead to have a very large fusion-

splicing loss and reduce the strength of the fusion-splicing points.

Steps of replacement of the needle electrode:

 To turn off the power supply of the Optical Fiber Fusion Splicer.

 To screw out fixing screws, and remove the old needle electrode

suffered from electric shock.

 To use a tissue just having had a dip in alcohol to clean the new

needle electrode, and then install correctly the needle electrode

on the Optical Fiber Fusion Splicer and tighten the fixing screws.

 To turn on the power, and put the prepared fiber into the Optical

Fiber Fusion Splicer to do the discharge tests.

1-1. “Arc Test”

In order to ensure the stable fusion-splicing quality, the user

should operate regularly. It is necessary to do arc test in case of

using the Optical Fiber Fusion Splicer under the following

conditions: ultra-high temperature, ultra-low temperature, very dry,

very wet, electrodes degradation, fusion splicing of the

heterogeneous optical fibers, cleanness, or after replacing the

electrode.

The arc test needs to use two optical fibers being ready to be

fusion-spliced, according to the general method of fusion splicing,

these optical fiber should be stripped, cleaved off, and placed on

the fixture. Press to enter arc test program. When seeing

“Place fiber and press Enter” , place the fiber well and press the

18

After arc, a numeric value will be displayed on the screen. If the

value is within the range of 45-65, it means that the arc power is

OK. If the value is less than 45, it means that the arc power is

weak, if more than 65, arc power is too strong

After arc, if shown weak or strong, please press , store the

record , and then do arc test again until shown the proper arc

power value.
