Appendix B. Practice Splicing
General Precautions
• Refer to the 915FS and 915CL user manual.
• Clean all connectors before making a connection.
It is highly recommended that new 915FS users use the AUTO mode splicing
profile until they have become proficient at splicing.
Checking the Splice Quality of the 915FS
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:
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 915FS.
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.
10. The splicing technician should repeat step 9 until they are able to reliably splice
using the desired fiber.
