DESIGNATION OF COMPONENTS OF OPTICAL FIBER FUSION SPLICER

MAIN POINTS OF FUSION SPLICING PROCEDURES

How to Get Small Splicing Loss 

 Necessary Regular Cleaning Jobs 

• Clean V-Shaped Groove
• Clean Reflecting Mirror
• Clean Optical Fiber Pressure Head
• Clean Objective Lens.

In case of cleaning Objective Lens it is unnecessary to remove needle electrodes.

Selection/Usage of Appropriate Splicing Modes 

Please select the appropriate splicing modes according to different sorts of the Optical Fibers.

Equipment Clean-up before Each Fusion Splicing Operation

• Clean the blades of Optical Fiber Stripper.
• Clean the rubber pad and blades of the Optical Fiber Cleaver.

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 cut length is correct. 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 cannot be, in the discharge process, fully close to each other, resulting in undesirable loss of fusion splicing.
• Do not tighten the optical fiber, otherwise, two optical fibers cannot 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.

• 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 centre of the heater, so as to avoid uneven heating and lead to additional losses.

 Power Supply

Please only use the AC Adaptor provided by the manufacturer.

Please only use the Storage Battery and Battery Charger provided by the manufacturer.

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.

Storage Battery 

Even if the storage battery is not used, its capacity will gradually go down over a period of time, 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.

 MAINTENANCE OF FUSION SPLICIGN QUALITY

CLEANING AND CHECKING BEFORE FUSION SPLICING

The following describes the maintenance checks for the key cleaning points and the important parts.

Cleaning the V-Shaped Groove

If there is dust or contamination in the V-shaped groove, the optical Fiber Pressure Head cannot suppress the Optical Fiber correctly, resulting in large loss of fusion splicing. So, in regular operation, it is necessary to check more often and clean regularly the V-shaped groove.

• Open the windproof cover.
• 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 swab.
• If contaminations in the V-shaped groove cannot 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.

Cleaning Up the Optical Fiber Pressure Head

If there are contaminations on the Optical Fiber Pressure Head, the optical Fiber Pressure Head cannot suppress the Optical Fiber normally, resulting in degradation of the quality of fusion splicing.

• Open the windproof cover.
• 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.

Cleaning the Windproof Cover and Reflecting Mirror

If there are contaminations on the surface of the Reflecting Mirror, the definition of the light pathways will drop, causing the position of the optical fiber’s core to be inaccurate, and to lead to the increase of the loss of fusion splicing.

• Clean the Windproof Cover and Reflecting Mirror with a cotton swab just having had a dip in alcohol (above 99 % alcohol), and remove the excess alcohol on the surfaces of the Windproof Cover and Reflecting Mirror with a dry cotton swab.
• There should be no Stripes and stains on the surfaces of the Windproof Cover and Reflecting Mirror.

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)

 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 device 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.

 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.

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.

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:

• Turn off the power supply of the Optical Fiber Fusion Splicer.
• Screw out four fixing screws, and remove the old needle electrode suffered from electric shock.
• 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.
• Turn on the power, and put the prepared fiber into the Optical Fiber Fusion Splicer to do the discharge tests.

“Arc Test” Function

In order to ensure the stable fusion-splicing quality, the user should regularly operate. It is 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, or after replacing the electrode.

The discharge tests need to use two optical fibers being ready to be fusion-spliced, and according to the general method of fusion splicing, these optical fibers should be stripped, cleaved off, and placed. Press “ENTER” to enter discharge tests program.

After the discharge, a numeric value will be displayed on the screen. If the value is within the range of 20-40, it means that the discharge strength is normal. If the value is less than 20, it means that the discharge strength is weak, and it is necessary to increase the discharge strength corresponding to the executive program. If the value is greater than 40, it means that the discharge strength is too strong, and it is necessary to reduce the discharge strength corresponding to the executive program.

After the discharge, if the Optical Fibers at both sides are different in the fusion degrees, it is necessary to increase the “Gap Position” value in the “System Setting” Menu in case that the fusion degree of the optical fiber at the right is high; and it is necessary to reduce the “Gap Position” value in the “System Setting” Menu in case that the fusion degree of the optical fiber at the left is high.

“Stabilize Electrode” Function 

When a sudden change occurs in the external environment, the discharge strength may sometimes be unstable, resulting in larger fusion-splicing loss, especially, when the optical fiber fusion splicer moves from a low-altitude area to a high-altitude area, it is necessary to take a certain time to stabilize the discharge strength. In this case, the stable electrodes can accelerate the process of discharge strength’s stability, but it is necessary to do discharge trials many times so as to stabilize the electrode.

 Troubleshooting

TURNING ON POWER OF OPTICAL FIBER FUSION SPLICER AND POWER SUPPLY

·       Turn on the power switch, but the power supply does not respond.

Reason:

1. Power outlet is not plugged in.
2. The contact of the power switch is bad.
3. The storage battery is not properly inserted in.

Solution: Check to see if the power plug or the storage battery is plugged/inserted in well or not, and is connected to the optical fiber fusion splicer well or not. Then, check to see if the power switch is good or not.

• In case of turning on the optical fiber fusion splicer, it has no reaction. (The screen does not brighten.)

Reason:

1. The power supply fuse disconnects.
2. There is the short-circuit or the failure occurs inside the optical fiber fusion splicer.
3. The electricity capacity of the storage battery is not large enough or the polarity is connected in reverse direction.
4. The AC adapter is bad, the voltage output is not correct.
5. The display screen is bad.

Solution:

Check to see if the power supply fuse disconnects or not, and to see if there is the short-circuit or other failure occurs inside the optical fiber fusion splicer. Replace the power supply fuse on the main board. If there is the short-circuit or other failure inside the optical fiber fusion splicer, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

Check to see if the electricity capacity of the storage battery is large enough or not. If it is not large enough, it is necessary to discharge the storage battery. Check to see if the battery polarity is connected in correct direction or not. If it is connected in reverse direction, it is necessary to correct it.

Check to see if the voltage output of the AC adaptor is normal or not (the output voltage should be 12 V). If it is not normal, it is necessary to replace the former AC adaptor by a new one. The brightness of the display screen has been well adjusted at the factory, if the display screen cannot properly show, it indicates that the display screen is faulty, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• After turning on the optical fiber fusion splicer, it always shows “system reset” and the equipment is at all times in the “Reset” status.

Reason:

1. The photoelectric switch of the optical fiber fusion splicer is faulty.
2. The motor or the motor drive is faulty.

Solution: please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

 FUSION SPLICING OPERATIONS

• After having placed the optical fiber, there appears a very dark image or a dim image on the half of the display screen.

Reason:

1. The windproof cover is not correctly put in its position
2. The reflecting mirror in the windproof cover is positioned with a deviation angle.
3. The corresponding light does not shine.
4. The corresponding CCD signal control lines fall off or the CCD is faulty.

Solution: Check to see if the windproof cover is covered or not, with or without foreign body sticking the windproof cover. Adjust the angle of the reflecting mirror to the right position. Check to see if the corresponding light does shine or does not. If it does not shine, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• Press the “AUTO” key, but the optical fiber stops moving; press the “RESET” key, and it is able to normally reset the system, but the optical fiber still does not move. Reason:

1. The optical fiber is broken off.
2. The press board of the optical fiber did not pin the optical fiber.

Solution: Produce the optical fiber again. Lay the optical fiber again. Shut the press board, and gently pull the optical fiber back by hand. If the optical fiber can be easily pulled to move, it indicates the press board did not pin the optical fiber. Check to see if the compaction bar of the optical fiber is able to bounce or not. If the compaction bar is not able to bounce, it needs to be repaired.

Press the “AUTO” key, and the optical fiber moves forward to a certain position, and then moves forward again, and finally there will be shown “Lay Optical Fiber Again”.

Reason:

1. The length of the cleaved optical fiber is unable to meet the requirements.
2. There is an obstacle for the press board of the optical fiber to move forward.

Solution: The length of the cleaved optical fiber should be about 16mm. If it does not meet the requirements, it is necessary to produce the optical fiber again. In the advancing direction of the press board of the optical fiber, gently push by hand the press board of the optical fiber, and to check to see if it has an obstacle or not. If it has an obstacle, it is necessary to find its location, and handle it.

• Press the “AUTO” key, and in the course of the core-to-core of the optical fibers, the image of the optical fiber at one side is moving up and down in the vertical direction, and the end-faces of the optical fiber at two sides are not core-to-core, so that it is unable to do the fusion splicing.

Reason:

1. There is the dust on the precision V-shaped groove, so that the position of the optical fiber at one side is somewhat higher, the data of which is greater than the max. position value of the optical fiber at the other side moving up and down.
2. There are the dust and dark spots on the objective lens’ surface, the lights, the reflecting mirrors, and the CCD has dust or dark spots.

Solution: 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 swab. If contaminations in the V-shaped groove cannot 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. Also, clean the objective lens’ surface, the lights, and the reflecting mirrors with a cotton swab just having had a dip in alcohol (above 99% alcohol), and remove the excess alcohol on the objective lens’ surface, the lights, the reflecting mirrors with a dry cotton swab. If it is still impossible to solve these issues, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• There often occurs that the fusion splicing is done despite of optical fibers being not core-to-core, so that after completing the fusion splicing, there will be shown a large loss or a failure in the fusion splicing.

Reason:

1. An optical fiber is dirty, and its end-face is bad.
2. There are the dust and the dark spots on the objective lens’ surface, the lights, the reflecting mirrors.

Solution: Produce the qualified optical fiber again. Clean in the same way, the objective lens’ surface, the lights, and the reflecting mirrors with a cotton swab just having had a dip in alcohol (above 99% alcohol), and remove the excess alcohol on the objective lens’ surface, the lights, the reflecting mirrors with a dry cotton swab. If it is still impossible to solve these issues, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• There always occurs that the end-face of the optical fiber at one side is not good.

Reason:

1. In the Menu, the value of “End-Face Setup” is somewhat small.
2. There are the dust and dark spots on the objective lens’ surface, the lights, and the reflecting mirrors’ lens.
3. The corresponding light does not shine.
4. There is the dust in the V-shaped groove, or the optical fiber had not properly been laid into the V-shaped groove.

Solution: Enter the Menu, and increase the value of “End-Face Setup “. Clean in the same way, the V-shaped groove, the objective lens’ surface, the lights, and the reflecting mirrors with a cotton swab just having HAD a dip in alcohol (above 99 % alcohol), and remove the excess alcohol on the V-shaped groove, the objective lens’ surface, the lights, and the reflecting mirrors with a dry cotton swab. Check to see if the corresponding lights are normal or not, and to see if the optical fiber had properly been laid into the V-shaped Groove or not. If it is still impossible to solve these issues, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• The electrode does not discharge in the course of the fusion splicing.

Reason:

1. The program without the set parameters had been selected or in the program the discharge strength is set to 0.
2. The high-voltage power supply is damaged or the electrode connecting cable falls off.

Solution: Check to see if the selected program is correct or not, or to see if the set discharge strength in the program are proper or not. If it is still impossible to discharge normally, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• The fusion splicing phenomenon is normal, but the loss of the fusion splicing has been somewhat large at all times or there occurs the failure in the fusion splicing.

Reason:

1. There occurs the failure in the detection system or there is the dust on the objective lens and the reflecting mirrors’ lens.
2. In the parameters, the value of “End-Face Setup” of the optical fiber is larger.
3. After the operations of the electrode discharge and the fusion splicing, the windproof cover is opened before the equipment has completed its detection.

Solution: Clean in the same way, the objective lens’ surface, the lights, and the reflecting mirrors with a cotton swab just having had a dip in alcohol (above 99 % alcohol), and remove the excess alcohol on the objective lens’ surface, the lights, the reflecting mirrors with a dry cotton swab. Check to see if the value of “End-Face Setup” of the optical fiber is larger in the parameters or not. Then operate the electrode discharge tests again, until the discharge current is moderate.

Press the “AUTO” key, and the gap setting and the core-to-core adjustment are normal, but it fails in completing the fusion splicing, resulting in always two balls.

Reason:

1. The fusion-splicing current is too large, and the environmental humidity is too high.
2. The advancing amount is somewhat small or is 0; the advancing speed value is somewhat large.
3. The optical fiber’s press board did not pin the optical fiber.
4. The quality of the optical fiber itself is poor, being disengaged from its cladding.

Solution: Change the fusion-splicing environment to a dry one, to see if there is that issue. Confirm that for the fusion-spliced optical fiber, there is no phenomenon that it is disengaged from its cladding. Enter the “Applications Program” menu; check the parameter setting and set the correct parameters; and then do the electrode discharge tests again, until the discharge current is moderate

The multi-mode optical fiber is blistered, becoming thicker or thinner after its fusion splicing.

Reason:

1. The end-face of the optical fiber is unqualified or the surface of the optical fiber is dirty.
2. There is an issue about the parameter setting in the program.

Solution: Ensure that the end-face of the optical fiber is good, do the electrode discharge tests until the discharge current is moderate. If the optical fiber is still becoming thicker or is blistered, it is necessary to increase the values of the “Pre-Fusion Current” and “Pre-Fusion Time” in the program. In reverse, if the optical fiber is still becoming thinner or is blistered, it is necessary to decrease the values of the “Pre-Fusion Current” and “Pre-Fusion Time” in the program, and increase the quantity of the “Fusion-Splicing Boost”.

• The fusion splicing loss index has been somewhat large at all times.

Reason:

1. There is the dust on the optical fiber, and in the V-shaped groove of the Fusion Splicer.
2. The discharge current is not moderate.
3. Do the optical fiber fusion splicing without having made the optical fibers being core-to-core.
4. The electrode aging.
5. The parameters set in the program are not proper.
6. The end-face of the optical fiber is not good, and there is an issue about the optical fiber cleaver.
7. The operating environment is rather poor, such as: the gale or wet, etc.
8. The optical fiber is more special.

Solution: First of all, it is required that the test method should be correct, then do all kinds of cleaning (for the V-shaped groove, the objective lens, the lights, the reflecting mirror, and the needle electrodes); select the appropriate procedures to do the discharge tests; adjust the optical fiber cleaver to ensure that the end-face of the optical fiber is well-cleaved. If the fusion splicing loss index is still somewhat large, you may do the parameter setting many times so as to find the better parameters for the fusion splicing, by way of increasing or decreasing the values of the “Pre-Fusion Time, Pre-Fusion Strength, Pre-Fusion Boost Quantity, and Pre-Fusion Boost Speed”, or you may reset the parameters to be the default parameters set at the factory. If it is still impossible to solve these issues, please contact your dealer to repair/maintain it or send it back to the factory for repair/maintenance.

• It is sparking on the electrodes or the electrode is sparking to the metals nearby it.

Reasons:

1. The electrode connecting cable is loose.
2. The operating environment is humid.

Solution: Check to see if the electrode connecting cable is loose or not. Change the operating environment to be the dry one, to see if there is the said phenomenon or there is not.

HEATING OPERATION   

• The optical fiber heat-shrinkable sleeve has not completely shrunk.

Reason:

1. The set heating time is too short.
2. As the outside temperature is too low so that the heating has not been fully and completely done.

Solution: Adjust the program to extend the heating time.

• The optical fiber heat-shrinkable sleeve adheres in the heating tank.

Reason:

Some optical fiber heat-shrinkable sleeve may cause adhesions.

Solution: Take out the optical fiber heat-shrinkable sleeve after it is completely cooled. Or use a cotton swab to lightly poke at its edges to break it away from the heating tank.
