Introduction
[7]
Introduction The Large Diameter Splicer (LDS) is designed forsplicing optical fibers and other optical devices that are beyondthe capability of conventional optical fiber splicers. The LDS is asemi-automated fiber processing station that provides far morerange of positioning adjustment than conventional optical fibersplicers. Depending on options selected, up to ten separate angularand positional axes can be controlled, allowing unprecedentedadjustment of the geometry of the splice. A sophisticated GUI, inconjunction with two high magnification, 2 MP, telecentric cameras,provides detailed real-time feedback of fiber position and shapeboth before and after the splice. The exclusive 3SAE Ring of Firetechnology provides a highly controllable plasma field thatcompletely surrounds the fibers for even heat distribution.Sufficient power is available to splice silica fibers up to 2.5mmin diameter. Similarly-sized optical devices such as lenses andprisms can also be spliced, with appropriate fixturing. Both thepositioning features and the Ring of Fire unit are controlled by awell-documented serial protocol that allows unprecedented useraccess to all aspects of the units operation, either manually or inconjunction with user-created software. This manual is intended toinstruct the user in the routine use, adjustment, and maintenanceof the LDS.

Safety Warnings and Precautions
[9]
Safety Warnings and Precautions
READ THE INFORMATION BELOW!!! Many of these safetyconsiderations are not obvious!
No coating materials containing fluoropolymers (such as PTFE orfluoroacrylates) or fluorine in any form should ever be exposed tohigh temperatures or electrical plasmas (such as in the LDS unit),as Hydrogen Fluoride and other highly toxic materials will beproduced.
It is the responsibility of the user to determine the chemicalmakeup and decomposition products of materials to be used in theLDS. Use appropriate protective measures as needed.
Operate only in a well-ventilated area. All flames and plasmadischarges in air produce ozone and nitrogen oxides in some amount.Sufficient ventilation must be provided for operatorprotection.
Do not touch the electrodes or adjacent areas while the unit ispowered on or connected to the power supply. The electrodes producehigh voltages and high temperatures that can cause burns andelectrical shock, possibly causing serious injury or death.
Fiber containing electrically conductive materials, such ascarbon coating or metallization layers, should not be used withoutspecific consultation with 3SAE Technologies Engineering Personnel.Electrically conductive fibers may cause a shock hazard, due to thehigh voltages employed in the unit.
The positioning motors of the unit can be operated with thecover open. These positioning stages move very slowly, but candevelop high forces due to the gear ratios involved. Keep clear ofpinch points and keep hair, jewelry, and clothing away from movingparts.
If required, an external safety panic button may be connected soas to disconnect power from both of the AC adapters of the LDS.Interruption of power will not damage the LDS. Be aware that amotor reset will occur when power is reapplied.
The LDS is equipped with a safety interlock that requires thelid to be closed before the LDS can fire an arc. The LDS is alsoequipped with a thermocouple to prevent the unit fromoverheating.
The LDS power supply is rated for UL and CE
Overvoltage Protection: Typical 125% max
Overload Protection: 120-150% hiccup/trip & restart modewith auto restart
Short Circuit protection: Continuous
Temperature Coefficient 0.04%/C
Efficiency: 85% typical at 230 VAC & 100% load
Safety Approvals: EN60950-1, UL1950-1, CSA C22.2 No. 60950cUL
Do not attempt to defeat or circumvent the safety interlock onthe top cover. Also, do not rely on the interlock: disconnect thepower supply entirely when working on or near the electrode blockassembly.
The use of safety glasses is recommended. Fragments of fiber cancause injury if they come into contact with eyes.
Observe all safety precautions common to the handling of opticalfibers and dispose of fiber scraps safely.
Do not operate the LDS in the vicinity of flammable vapors orliquids. Operation of the unit in such an environment may increasethe risk of fire or explosion.
The LDS is designed to splice optical glass fibers. Operation ofthe unit in applications other than the intended use can causedamage to the unit.
Safety Warnings and Precautions
[10]
Use only the A/C adapters that are supplied with the LDS. Usingan improper power supply may permanently damage the LDS.
Do not modify or disassemble the LDS or any of its accessories,including the power supplies.
Turn the LDS off when not in use.
Never plug in a power supply to the cameras. All cameras arepowered through the USB cable.
Do not expose any portion of the LDS to water or otherliquids.
The use of compressed gas or canned air to clean the LDS cancause damage to the unit. These products can contain flammablematerials or contaminants that may ignite during the electrodedischarge.
Use only factory specified electrodes; the use of non-factoryelectrodes can potentially damage the LDS.
Applications for the LDS should be developed only by personswith a full technical understanding of the materials to be used(fibers and coatings). These persons must give full considerationto the safety implications of the process to be used.
Use of the unit should be restricted to personnel that: Havebeen appropriately trained in the handling of optical fiber andrelated materials. Have read, understood, and will follow all usageand safety instructions in this manual.
Note: It is the responsibility of the user to use this productfor its intended purpose and according to this manual. 3SAETechnologies cannot be responsible for damages or injury resultingfrom failure to follow these instructions.

Global Arc Power This a DC power offset that will be added orsubtracted if a negative value is entered to the splicing powersand manual arcing powers. This feature is commonly used tocalibrate multiple splicers to one another. The default is 0, butwill accept -255 to +255 values. Camera Speed This controls theframe rate that the cameras are recording. Typically 1/2 speed issuggested. 0=full speed, 1=half speed, and 2=1/4 speed. Full speedhas a frame rate of 15 frames per second. Piezo Factor This valueis a DC offset to the Piezo Distance Moves, i.e. if there is aPiezo Move of 60 and a Piezo Factor of 0, the Piezo should move 60,but if measured and the Piezo does not move 60, instead it moves55, the Piezo Factor should be changed to 5. Piezo Home Piezo homeis the piezo location of the left platform when the fast align isactivated. The purpose of advancing the piezo forward is so thepiezo can move backward, if needed, when setting the gap. ThetaZero Position This is only available with PM functionality. This isthe calibrated theta rotation that represents how far from the homeit takes to reach 0. This is calibrated at the factory and againduring installation of the LDS. This should only be done with acalibration kit. Load X & Y Motors When toggled green, it willload the X and Y motors when the software is played. When toggledred, the X and Y motors will not be loaded. Check Box in the Load X& Y Motors This check box, if checked, will home the X and Ymotors when the software is played. Fiber Vision Factor Top Thismultiplier is used to correlate pixels to microns. This parametershould never be adjusted unless the cameras or lenses are replacedor modified. It is suggested to write down your settings beforeusing the splicer. This can be adjusted by placing a fiber in viewof the camera of a known diameter and use the measuring tool todraw a box around the O.D. of the fiber. You can select themagnifier tool to zoom in to ensure the ROI (region of interest)box is accurately drawn on the fiber. You will need to right clickand click "Zoom to Fit" to zoom out for the measured numbers toappear. Adjust the vision factors until the measured valuedisplayed matches the know fiber diameter. Default with Doublers is2.18 Default without doublers is 1.09 Fiber Vision Factor Side Thismultiplier is used to correlate pixels to microns. This parametershould never be adjusted unless the cameras or lenses are replacedor modified. It is suggested to write down your settings beforeusing the splicer. This can be adjusted by placing a fiber in viewof the camera of a known diameter and use the measuring tool todraw a box around the O.D. of the fiber. You can select themagnifier tool to zoom in to ensure the ROI (region of interest)box is accurately drawn on the fiber. You will need to right clickand click "Zoom to Fit" to zoom out for the measured numbers toappear. Adjust the vision factors until the measured valuedisplayed matches the know fiber diameter. Default with Doublers is2.18 Default without doublers is 1.09 ROF Speed This is the defaultspeed that the ROF Module run during homing and some sub routines.This speed should be defaulted to 1200 um/sec. ROF Home This is thedefault home position of the ROF Module. If your LDS has a cleaverinstalled the home position should be ~14500. If you do not have acleaver, it will be 0.

Stop Program TheStop Program button properly stops the execution of the program byreleasing computer resources related to the USB and serialinterfaces. Note: Closing the program by any other method is likelyto cause error messages both during the shutdown and the subsequentrestart of the program Configuration File (Save/Load) This savesthe every variable from each tab of the LDS so that they can beloaded at later time. The factory default Configuration File isprovided with on disc as a backup. Note: Programs will over rightthe Configuration File Tension Offset DC offset that will be addedto the load cell. Most always this parameter will be 0. TensionSpeed Motor speed in microns per second of the left and rightstepper motors. Default is 10. Tension Overshoot The amount ingrams that the tensioning process will over shoot prior to settingthe desired tension. Default is 5. Tension Delay Wait time (eachunit is equal to 10 ms) after the overshoot tension has beenreached, but before adjusting the desired load. Default is 30.Tension Window Plus/minus window of acceptable tension. Default is10. PM Mirror Installed This box should be checked if there is a PMmirror installed on the LDS. By checking this box, the right motorwill not move closer than the set limit of the box below labeled"mirror/right stage limit". This limit is designed to prevent theright fiber holder from crashing into the mirror arm. ROF / RightStage Limit This is a variable that will not allow the arc to firewhen the distance between the ROF and the right stage is less thanthe variable set. Most splicers do not use this unless they areequipped with custom fiber holders that are longer than theoriginal. Side Align Offset This will automatically add an X offsetto the fusion splice in microns after the X and Y alignment iscompleted. Top Align Offset This will automatically add a Y offsetto the fusion splice in microns after the X and Y alignment iscompleted.

Push Distance This is the travel distance in microns of the leftfiber during the push stage of the splice. Some systems areequipped with a piezo drive that is used to create this motion butthe standard LDS system will drive the left Z stage this distance.This value should always exceed the Total Fiber Gap measured by theGet Data button. The Piezo can move as slow as 3um/sec and as fastas 788um/sec. The stepper motors can move as slow as 15um/sec andas fast as 3000um/sec. Pull Distance This is the travel distance inmicrons of the left fiber during the pull stage of the splice. Somesystems are equipped with a piezo drive that is used to create thismotion but the standard LDS system will drive the left Z stage thisdistance is a backward direction. Splice Mode Selects which pushingmethod during the splice; Piezo, left stepper, or both the left andright stepper motors. ROF Splice Offset This is the offset locationin microns of the ROF during the splice. Unlike many splicers thatmove the fibers from the center of the screen for an offset splice,the LDS system can alter the heat source location of a splice tointentionally offset the heat distribution when splicing dissimilarfibers. This is useful because the fibers are still centered on thescreen. For similar fiber splicing, the ROF location should be onthe red center line. For a dissimilar splice, the ROF locationshould be altered from this center. Cleave Angle Limit This is theacceptable cleave angle limit for splicing. View Angle Limit Thisis the acceptable view angle (pitch/yaw) limit for splicing.Low/High Power This is the power range for the arc, i.e. for 1000umand smaller diameter fibers, Low Power is recommended and for1000um and larger diameter fibers, High Power is recommended. Clickon the box to toggle between Low Power and High Power. Low Power isconsidered higher resolution. Left Reset Position This is the homeposition for the fiber when Splice Reset is enabled. Right ResetPosition This is the home position for the fiber when Splice Resetis enabled. Y Reset Position This is the home position for thefiber when Splice Reset is enabled. X Reset Position This is thehome position for the fiber when Splice Reset is enabled.

Right/Left Choosing left or right will determine the side thatthe tool is measuring. If "Right" is clicked, the right side of thescreen will be "blacked-out" and it will measure the radius fromthe center line to the left of the screen. When setting up tomeasure the radius of a lens, place the fiber in the right fiberholder, position the fiber so the peak of the radius or the largestpart of the radius is on the center vertical line, toggle radius toturn on, and toggle radius to turn off. Averaged Radius This is thecombined radius averages of the Top and Side views. Arc ControlThis window provides control of the arc power and balance settings.Arc Gain The camera gain will automatically change to this settingwhen the arc is manually initiated by using Arc On. Arc On Turnsthe arc on based on the Arc Power setting. Arc On Click to turn onthe arc manually based on the arc power and arc time settings inthe arc control box. Arc Abort Turns arc off at any time when ithas been initiated by Arc On. Arc Position Selects the Current orArc Position. This is where the arc will initiate when the Arc Onis pressed. Low Power This is the power range for the arc, i.e. for1000um and smaller diameter fibers, Low Power is recommended andfor 1000um and larger diameter fibers, High Power is recommended.Click on the box to toggle between Low Power and High Power. LowPower is considered higher resolution. Set Arc Balance This setsthe Arc Balance after the slider has been moved to a new location.Set Arc Power This updates the Arc Power when changed. If youchange the Arc Power you must click Set Arc Power before the changewill be updated. Arc Power The minimum setting is 0 and the maximumsetting is 255. However, the arc may not fire at 0 depending on thearc gap and the arc balance. Arc Time This is the arc time thatwill be used if the arc is manually initiated by arc on. The rangeis from 0.1 to 99.9. Arc Power This is the arc power that will beused if the arc is manually initiated by arc on. The range is from0-255. Arc Balance Slider (side) This adjusts the arc balance orthe intensity of the plasma field horizontally. To check the arcbalance for LDF applications place a piece of ~1mm (or an operatorpreferred LDF fiber) across the V grooves and manually initiate thearc at a power level of 100. The light intensity should besymmetrical from top to bottom as the fiber is heating up in theSide View camera. If the arc is more intense on the top, loweringthe arc slider would shift the intensity from the top to thebottom. The Default setting is 170. Note: This value should notneed to be changed, but if changed, be aware that changing thisvalue can change the overall power of the plasma field and are-optimization and possible verification of the splicing programis suggested The Arc Balance values are saved in the Excel filesfor each splice.

Arc Balance Slider (bottom) This adjusts the arc balance or theintensity of the plasma field vertically. To check the arc balancefor LDF applications place a piece of ~1mm (or an operatorpreferred LDF fiber) across the V grooves and manually initiate thearc at a power level of 100. The light intensity should besymmetrical from top to bottom as the fiber is heating up in theTop View camera. If the arc is more intense on the left or right,moving the arc slider either left or right would shift theintensity from the left to the right, or vice versa. Note: Thisvalue should not need to be changed, but if changed, be aware thatchanging this value can change the overall power of the plasmafield and a re-optimization and possible verification of thesplicing program is suggested The Arc Balance values are saved inthe Excel files for each splice.

X & Y Motor Movements
[49]
X & Y Motor Movements The motors have 12mm of travel and aresettable in 0.1um increments. Each motor needs to be homed afterthe LDS has been turned on. If the software GUI is turned off andback on but the LDS is not powered down then homing should not benecessary. The reason that they are not homed automatically is thatit is often not desirable to lose a fiber alignment each time theGUI interface is turned off. Once the motors are homed the operatorshould manually set the Y motor (up and down) to ~10mm and the Xmotor to ~6mm from home. Depending on the fiber and V-grooves beingused, this should place the fibers approximately into the view ofboth cameras so that automatic alignment can occur when executed.The controllers and motors are from a third party and theinformation below is extracted directly from the manual of themotor controller. Digital Display This shows the position (inmillimeters or degrees) of the motor. The motor must be homedbefore the display will show a meaningful value, i.e. the displayedposition is relative to a physical datum, the limit switch. Home YThis sends the motor to its home position. Fine X/Y Step Size Thissetting adjusts the Fine Step Size of the jog function for both theX and Y motorized alignment. Course X/Y Step Size This settingadjusts the Course Step Size of the jog function for both the X andY motorized alignment. Master Gain Splice This is the master gainof the LDS and controls both cameras. EFI Gain Splice This is themaster gain of the EFI camera. Fine X/Y Step Size This settingadjusts the Fine Step Size of the jog function for both the X and Ymotorized alignment. Course X/Y Step Size This setting adjusts theCourse Step Size of the jog function for both the X and Y motorizedalignment.
Arc Counter
[50]
Arc Counter The LDS records the count of the electrodesinstalled in the unit as well as a life counter. Arc Counter Thisis considered the life counter of the LDS. Every time the arcfires, either manually or automatically, this number will increaseby an increment of one. Use Counter This is an algorithm thatmultiplies the power level of the arc by the time the arc is on.This is used as an electrode life counter. This number will varydepending on how the LDS is used, i.e. tapering, large diametersplicing, PM splicing, etc. Reset Arc Counters This is used when anew set of electrodes is installed into the LDS.

Fiber Diameter Scan
[52]
Fiber Diameter Scan When executed, the Fiber Scan measurescenter of the screen and begins translating the left and rightstages simultaneously in the direction selected; the fiber scanfeature begins measuring the outer diameter if the fiber. Thisprogram is useful when analyzing Splice Push and Splice Pullparameters as well as taper and MFA mechanical results (if yourunit has these functions) as well as quantifying the result of ataper. Both Top and Side views are scanned and plotted on thegraph.
Fiber Diameter Scan Graph
The data collected during a fiber scan is displayed here. Thegraph can be saved checking the box Labeled Save Graph. You mayalso overlay the load cell data (image below doesnt have the loadcell data present) by checking the box labeled Overlay Load CellData. The graph is also scaling the absolute stepper motorposition.
Performing a Scan
1 Enter a scan speed in the speed text field. 400 (400um/sec) isthe default speed. 2 Check Scan Max if you wish to scan the maximumdistance of travel and stop at any time, or you can uncheckscan
max and enter in the distance you wish to scan. 3 If cleaving,toggle the scan only/stop for cleave button so that the stop forcleave is displayed and the button is
yellow. 4 Enter in the diameter that you wish to cleave at. 5Select the direction that you want the motors to move during thescan. 6 Check save graph. 7 Check overlay load cell data. 8 Checksave absolute scan data. 9 Click begin scan. 10 Wait for scan tostop or you may stop the scan at any time. 11 Save data as pop-upsare displayed.
Camera Windows
[53]
Camera Windows The LDS has two orthogonal cameras and aredisplayed in two windows. Note: The images displayed in bothwindows can be saved by right clicking on the individual displayand choosing Save Data. This function saves the image to theWindows Clipboard and can be pasted into most standard programsNote: Both views have the capability of Digital Zoom. The DigitalZoom can be accomplished by left clicking the mouse button ineither the Top View or Side View. The window can be returned to theoriginal size by right clicking in the window and selecting Zoom toFit.
