Appendix B. Practice Splicing

General Precautions
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 fiber that they will use in their
installation before attempting to splice fibers in those installations.
The following procedure should be used to practice fusion splicing fiber cables:
10. The splicing technician should repeat step 9 until they are able to reliably splice

• Refer to the 910FS and 910CL user manual.
• Clean all connectors before making a connection.
1. Identify the field fiber type by consulting the fiber manufacturer's data sheet.
2. Obtain an approximately 10 m length of fiber (same as field fiber).
3. Determine if this fiber type has a pre-programmed splicing profile in the 910FS.
Use this profile for splicing.
4. If there is not an exact matching splice profile, use the AUTO mode splicing profile.
5. Splice a fiber pigtail with a suitable connector for their source/power meter of like
fiber to one end of the 10 m fiber.
6. Splice a fiber pigtail with a suitable connector for the source/power meter of like
fiber to the other end of the 10 m fiber.
7. Connect a laser (SM) or LED (MM) source to one end of the fiber and a power meter
to the other end of the fiber. Refer to Figure 1.
8. Zero the power meter. Refer to Figure 2.
9. Cut the 10 m piece of fiber in the middle and splice it back together. The power
meter should read 0dB PLUS allowable splice loss X2.
