Preface
Description
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.

Section 2. Operation
Setup
Installing Battery in Splicer
The 910FS can be powered by an external power adapter and battery.
Inserting the Battery
Remove the protective cover from the battery contacts. Insert the battery into the battery
compartment until it clicks into place.
Removing the Battery
Turn off the splicer. Push the release button, located on the side of the splicer body, and
remove the battery.
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.

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.
• 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.

14
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.
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.

16
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.
Cooling Tray
Place the splice into the cooling tray on the back of the 910FS splicer.
Splice-on Connectors
The 910FS uses the Greenlee version of splice-on connectors. The 910FS currently
supports SC, LC, FC, and ST versions (both PC and APC nish, where applicable).
Follow the instructions supplied with the SOC packaging.
