Typical Jacketed Fiber Construction
When working with a jacketed fiber, you must pare away the jacketing to expose the enclosed fiber.
The procedures for crimping and polishing are the same. However, when working with a jacketed
fiber, you will need to expose the fiber by removing a few millimeters of the black inner tube
jacketing.
Crimping Jacketed Fibers
Follow the steps below to attach and crimp an SMA connector to the end of a jacketed fiber using your
Fiber Optic Termination Kit.
► Procedure
1. Trim the end of the fiber jacketing to the appropriate length, exposing the enough of the bare
fiber so that it can thread through the hole in the SMA Ferrule. Use a razor blade or some
other stripping tool to expose the appropriate length of fiber (this tool is not included with the
Fiber Optic Termination Kit).
2. Place the SMA crimp sleeve (the hollow tube that accompanies the SMA connectors) into the
0.178 channel of the 5-cavity crimp tool and close the crimp tool so that it gently secures the
crimp sleeve into place.
3. Apply some epoxy to the inside of the SMA crimp sleeve and slide the crimp sleeve onto the
jacketing of the fiber.
4. Thread the exposed end of the bare fiber and the protective inner tube through the SMA
connector barrel and out of the hole in the SMA ferrule.
5. Spread the Kevlar strength member so that it encloses the SMA connector barrel.
6. Apply some epoxy to the exterior of the SMA connector barrel and slide the SMA connector
barrel inside the connector sleeve.
7. Firmly crimp the SMA connector barrel and the SMA crimp sleeve together so that the crimp
sleeve covers the Kevlar strength member, the SMA connector barrel, and the end of the outer
jacketing.
8. Apply a drop of epoxy to the tip of the SMA ferrule, directly where the bare fiber is protruding
from the ferrule tip.
9. Allow the epoxy to cure for a minimum of two hours.
