Preface

Description

910FS Splicer

The Greenlee Communications 910FS Optical Fiber Fusion Splicer is intended to fuse
bers, resulting in low splice loss and long-term stable splices. Splice loss depends on
certain conditions such as ber preparation, splicing parameters, and ber condition.

The 910FS fusion splicer uses a CDS (Core Detection System), which is also widely
known as PAS (Prole Alignment System). Two cameras sense the center of the core
of the bers, with the fusion splicer then adjusting in the X, Y, and Z dimensions to
automatically and precisely align the two ber cores. A fusing arc is applied, which then
provides the lowest loss fusion splice.

The 910FS with PAS technology is designed for splicing many types of optical bers.
It is small in size and lightweight, making it suitable for any operating environment. It is
easy to operate, and it splices fast while maintaining low splice loss.

remove the battery.

910FS Splicer

Two Methods of Checking Remaining Battery Capacity

• If the battery is already installed in the splicer, turn the splicer ON. The battery is
automatically identied, and the remaining battery capacity is displayed on the
“Ready” screen.

• Press the battery check button on the battery pack. The remaining battery capacity
is indicated on the LED indicator.

910FS Splicer

Turning Splicer ON

Press and hold until the LED on the keypad turns ON (green color).

?

The “Ready” screen is displayed after all the motors reset to their initial positions.

The power source type is automatically identied. If the battery is used, the remaining
battery capacity is displayed.

Splice Mode

Use SM splice mode for standard SM ber (ITU-TG.652) splicing. It performs splices in
9seconds and is the quickest mode for SM ber splicing.

Use AUTO splice mode if ber type is not identied. Splice takes 2 seconds longer but it
covers most conventional ber splicing for the following reasons:

• AUTO mode rst identies ber type by analyzing ber prole, and the splicing
condition is chosen for the type of ber. The types of bers covered by AUTO are
all the conventional bers, such as SMF (G652), BIF (G657), NZDSF (G655), MMF
(G651), etc. AUTO mode takes longer than the SM processes but is recommended
in cases where the ber type is not positively identied or if the user is new to fusion
splicing.

• AUTO mode uses an automatic arc calibration function, which monitors the splicing
process and ensures adequate arc power for the splice.

Automatic Arc Calibration Function

When the automatic ARC calibration function is enabled the previous splice’s ARC
power is used. If the ambient conditions or type of ber has changed an ARC calibration
may be required. The automatic arc calibration function works in AUTO modes only. It
is not active in the standard splice modes. When using those modes, performing arc
calibration before splicing is strongly recommended.

Fiber Preparation

Placing Protection Sleeve over Fiber

Place the protection sleeve over the ber. Clean optical ber with alcohol-soaked gauze
or lint-free tissue approximately 100 mm (4 in) from the tip.

Note: Splice-on connectors are pre-cleaved. Do not attempt to clean the ber on the
splice-on connector. Follow the instructions supplied with the splice-on connectors.

910FS Splicer

• Clean optical ber with alcohol-soaked gauze or lint-free tissue. Dust particulates
can enter the protection sleeve, resulting in a ber break or attenuation increase.

• Make sure ber is passed through the protection sleeve.

• When protection sleeve core tube is longer than the length of outer sheath, cut off
excess sleeve to avoid micro bend after heating.

Failure to observe these precautions may result in injury and may damage the unit.

13

910FS Splicer

Stripping and Cleaning Fiber

Use the supplied ber stripping tool to strip the outer coating 30 to 40 mm (1.25 to 1.5
in) from its tip. Thoroughly clean the ber with alcohol-soaked (99% or greater) gauze or
lint-free tissue.

Fiber Cleaving

Do not let the ber end-face touch anything. Place the ber into the universal adapter,
and insert the adapter into the 910CL. Follow the instructions for the 910CL to cleave
the ber.

Loading Fiber into Splicer

1. Open the wind protector and install the ber adapters into the splicer, making sure
the ber is positioned into the center of the V-grooves.

2. Close the wind protector.

Splicing Procedure

To ensure a good splice, the optical ber is observed with the image processing system
equipped in the 910FS. However, in some cases the image processing system cannot
detect a faulty splice. Visual inspection with the monitor is often necessary for better
splicing yield. Observe the following standard operating procedure:

• After bers are loaded into the splicer, press and the bers will move toward each
other. The ber motion stops and the cleaning arc is performed. The cleave angle
and end-face quality are checked. If the measured cleave angle is greater than its
set threshold or ber chipping is detected, the beeper sounds and an error message
warns the operator. The splicing procedure pauses. If no error message is displayed,
the below stated end-face conditions are used for visual inspection. If observed,
remove the ber from the splicer and repeat ber preparation. These ber cleave
defects may cause a faulty splice.

910FS Splicer

Chip Lip Incline

• After ber inspection, the bers are aligned core-to-core or cladding-to-cladding.
Cladding axis offset and core axis offset measurements can be displayed.

• After completion of ber alignment, an arc discharge is performed to splice the
bers.

• Estimated splice loss is displayed upon completion of splicing. Splice loss is
affected by factors stated in Section 5. These factors are taken into account
to calculate, or estimate, splice loss. The calculation is based on dimensional
parameters, such as MFD, cleave quality, and fusion splice shape after the splice.
If either the cleave angle measured or the estimated splice loss exceeds its
set threshold, an error message is displayed. If the spliced ber is detected as
abnormal, such as “Fat”, “Thin” or “Bubble”, an error message is displayed. If no
error message is displayed but the splice looks poor by visual inspection through the
monitor, it is strongly recommended to resplice.

910FS Splicer

Notes:

• Splice point sometimes looks a bit fatter than other parts. This is considered a
normal splice and does not affect splice loss.

• To change threshold for estimated splice loss or cleave angle, refer to “Splice
Mode” in this manual for details.

• Splice loss may be improved in some cases by additional arc discharges.
Press for an additional arc discharge (re-arc). Splice loss estimate and
splice check are performed again. Splice loss may be worsened in some cases
by additional arc discharges (re-arcs). Additional arc discharge can be set to
“disabled”, or limited to the number of additional arcs.

• Splicing result is automatically saved in splicer memory.

Arc Calibration

When a splicing session is rst started or if the splicing environment has changed, it is
recommended that the technician perform an arc calibration.

1. Place cleaved bers into the splicer.

2. Press and navigate to the “Maintenance” menu. Select “Arc Calibration.”

3. Follow the on-screen prompts.

Note: It might be necessary to push up to three times until “the arc adjust OK”
prompt is achieved.

Heating Protection Sleeve

1. Transfer the ber with protection sleeve from the centering device to the tube heater.

2. Close the tube heater lid.

Notes:

• Make sure the splice point is located at the center of the protection sleeve.

• Make sure the strength member in the protection sleeve is placed downward.

• Make sure the ber is not distorted.

• The splice-on connector must be installed on the right-hand side of the splicer
heater. Use heater prole #1 for the SOC.

3. Press to start tube heating. The beeper sounds and the HEAT LED (red color)
turns off when tube heating is completed.

4. Open the tube heater lids and remove the protected ber from the tube heater. Apply
some tension to the ber while removing it from the tube heater.

5. Visually inspect the nished sleeve to verify that no bubbles or debris/dust is present
in the sleeve.

Note: In AUTO mode, certain parameters cannot be changed.

Parameter Description

Arc Power In SM/DS/MM/NZ/AUTO modes the arc power is xed at 40 bits.

Arc Time Arc time is xed at 1500 ms for SM and DS modes, 2000 ms for

NZ mode, and 3000 ms for MM mode. This is automatically set
depending on the ber type when AUTO mode is selected.

Edit Mode for Splicing

• Fiber Type: Select or enter the name of ber being spliced.

• Mode Title1: Enter type of ber.

• Mode Title2: Enter alternate name of ber type.

• Align: Select Core, Clad or Manual options. In manual mode the user can control the

This is a general guideline for the user to control the fusion settings. Every type of ber
has its own characteristics and properties that may require the manual setting of these
parameters. The user will have to perform careful experiments with their individual bers
to obtain optimum results.

Cleaning Fiber Clamps (recommended daily)

Refer to Figure 3.

If contaminants are present on the clamps, proper clamping may not occur, resulting
in poor quality splices. The ber clamps should be inspected frequently and cleaned
periodically during normal operation. To clean the ber clamps, do the following:

Clean the surface of the clamps with an alcohol-impregnated lint-free cotton swab.
Remove excess alcohol from the clamps with a clean, dry lint-free cotton swab.

Cleaning Wind Protector Mirrors (recommended daily)

Refer to Figure 3.

If the wind protector mirrors become dirty, the ber core position may be incorrect due
to decreased optical path clarity, resulting in higher splice loss. To clean the mirrors, do
the following.

• Clean the mirror surface with an alcohol-impregnated thin lint-free cotton swab.
Remove excess alcohol from the mirror surface with a clean, dry lint-free cotton
swab.

• Mirror should look clean with no streaks or smudges.

Cleaning Objective Lenses (recommended weekly)

Refer to Figure 4.

If the surfaces of the objective lenses become dirty, normal observation of the core
position may be incorrect, resulting in higher splice loss or poor splicer operation.
Therefore, clean both of them at regular intervals. Otherwise, dirt may accumulate and
become impossible to remove. To clean the objective lenses, do the following:

• Before cleaning the objective lenses, always turn off the splicer.

• Gently clean the lenses’ (X-axis and Y-axis) surfaces with a dry lint-free cotton swab.
Using the swab, start at the center of the lens and move the swab in a circular
motion until you spiral out to the edge of the lens surface.

• The lens surface should be clean and free of streaks or smudges.

• Turn on the power and make sure no smudges or streaks are visible on the monitor
screen. Press X/Y to change the screen and check the state of the lens surface on
both the X- and Y-screens.

NOTE:

• Do not touch the electrodes when cleaning.

• It is recommended to clean the objective lenses when replacing the electrodes.

Cleaning the Electrodes

1. Insert the electrode tip into the hole of the electrode polisher and gently rotate the
electrode.

2. Wipe the electrodes with 99% pure IPA. Do not touch the electrode surface with
your ngers.

3. Re-install the electrodes into the splicer.

4. Perform an arc calibration to calibrate the power to the electrodes.

General Fusion Splicer Cleaning (recommended daily)

• Use the cleaning brush only to clean debris from general working area, never on the
lenses, V-grooves, or mirrors.

• Periodically clean the ber adapters with isopropyl alcohol and a lint-free cotton
swab. Never touch the ber clamping area of the ber adapters.

Cleaning Fiber Cleaver 910CL (recommended daily)

Refer to Figure 5.

If the circular blade or clamp pads of the ber cleaver become contaminated,
the cleaving quality could degrade. This may lead to ber surface or end-face
contamination, resulting in higher splice loss. Clean the circular cleaving blade and
clamp pads with a lint-free cotton swab soaked with isopropyl alcohol.

Appendix B. Practice Splicing

General Precautions

• Refer to the 910FS and 910CL user manual.

• Clean all connectors before making a connection.

It is highly recommended that new 910FS users use the AUTO mode splicing
profile until they have become proficient at splicing.

Checking the Splice Quality of the 910FS

The user should practice splicing with the type of ber that they will use in their
installation before attempting to splice bers in those installations.

The following procedure should be used to practice fusion splicing ber cables:

1. Identify the eld ber type by consulting the ber manufacturer’s data sheet.

2. Obtain an approximately 10 m length of ber (same as eld ber).

3. Determine if this ber type has a pre-programmed splicing prole in the 910FS.
Usethis prole for splicing.

910FS Splicer

Optical Source

4. If there is not an exact matching splice prole, use the AUTO mode splicing prole.

5. Splice a ber pigtail with a suitable connector for their source/power meter of like
ber to one end of the 10 m ber.

6. Splice a ber pigtail with a suitable connector for the source/power meter of like
ber to the other end of the 10 m ber.

7. Connect a laser (SM) or LED (MM) source to one end of the ber and a power meter
to the other end of the ber. Refer to Figure 1.

8. Zero the power meter. Refer to Figure 2.

9. Cut the 10 m piece of ber in the middle and splice it back together. The power
meter should read 0dB PLUS allowable splice loss X2.

10. The splicing technician should repeat step 9 until they are able to reliably splice
using the desired ber.

Testing Splicing Splice-on Connectors (SOC)

The 910FS can fusion splice SOC using the universal SOC adapters. Be sure to select
the correct SOC to match the eld bers before splicing.

The following procedure should be used to practice fusion splicing with SOC:

1. Identify the eld ber type by consulting the ber manufacturer’s data sheet.

2. Obtain a “ber patch cord” with same ber and connector style as the SOC that will
be used.

3. Connect a laser (SM) or LED (MM) source to one end of the ber and a power meter
to the other end of the ber. Refer to Figure 3.

4. Zero the power meter. Refer to Figure 4.

5. Obtain an approximately 10 m length of ber (same as the eld ber).

6. Determine if this ber type has a pre-programmed splicing prole in the 910FS.
Usethis prole for splicing.

7. If there is not an exact matching splice prole, use the AUTO mode splicing prole.

8. Splice a SOC to each end of the ber. This will be called the “SOC spliced patch
cord.”

attempt to re-install; discard it.

910FS Splicer

A B C D E

Cable Preparation

Slide the 900 μm strain relief boot and then the 27 mm mini splice protective sleeve over
the 900μm eld ber. Use the 910CL to cleave the eld ber. Insert the ber adapter
with the cleaved ber into the left-hand side of the 910FS fusion splicer. Make sure to
butt the 900 μm buffer up to the edge of the ber adapter. This will ensure that the mini
splice sleeve will adhere to both sides of the 900 μm buffer.

Installation

1. Disable the “Proof Test” on the fusion splicer.

2. Remove the factory dust cap from the connector.

Note: The extended dust cap may be placed on at this time, if so desired, to aid in

the transfer of the connector. DO NOT LEAVE THE EXTENDED DUST CAP ON THE
CONNECTOR, INSIDE THE FUSION SPLICE MACHINE.

3. While holding the connector rmly, pull down on the cleave protector to remove it
from the connector (Figure 1).

Note: Do not touch the cleaved ber stub with the protector or your ngers as this

may damage the factory cleave.

4. Insert the connector into the universal splice-on connector holder so that the back
end of the connector is ush with the end of the holder (Figures 2-5). Once aligned
properly, the connector should t freely into the holder with no force required.

Figure 2 (SC) Figure 3 (FC) Figure 4 (LC) Figure 5 (ST)

5. Insert the holder into the right-hand side of the splicer (Figure 6), making sure that
the ber stub lays properly into the V-groove block of the splicer. You may use the
ber positioning tool to help align the ber in the V-groove. The ber for FC and ST
splice-on connectors must have the ber laying in the end of the ber groove in the
V-groove. The ber positioning tool can be used to align the ber with the V-groove.
Turning the ber and/or the connector may also be necessary to accomplish this.
The FC/ST ber adapter may also need to be twisted slightly to ensure that the ber
is aligned with the V-groove.

Note: Make sure that
the edge of the 900
micron tight buffer is
even with the edge of
the 900 micron fiber
adapter.

Figure 6

Note: Remove the
extended dust cap
before initiating the
fusion splice.

6. Perform the fusion splice as described in the fusion splicer manufacturer’s
instructions.

7. Once the fusion splicing cycle is completed, remove the connector from the splicer
and slide the splice protection sleeve up to cover the splice. Make sure that the
splice protector is positoned against the connector body.

Note: The extended cap may be put in place now to aid in the transfer to the splice

sleeve oven.

8. Transfer the splice to the splice sleeve heat oven on the right-hand side (Figure

7). Verify the position of the splice sleeve is butted up against the metal portion of
the splice-on connector. Use the 60 mm heater mode #1 with center and edges
activated. Press the HEAT button to run the shrink cycle.

9. Verify that the splice protection sleeve is completely shrunk onto the ber to avoid
the end catching on the strain relief boot. If the splice sleeve is not completely
shrunk, then place it back in the sleeve oven and initiate a second heat cycle.

Note: Make sure that the splice sleeve has fully cooled before sliding the strain relief

boot into place. For SC connectors, install the outer housing onto the connector,
being sure to align the angled corners of the inner housing with those of the outer
housing (Figure 8).
