Essentials for Reliable Fiber Test Results
13
The gray mandrels included with the DTX-MFM2 are
compliant with ANSI/TIA-568-C for 62.5 µm fiber with a
3 mm jacket. Mandrels for 50 µm fiber are available from
Fluke Networks. Refer to the appropriate standard for
mandrel requirements if you follow other standards. Table
1 shows a partial list of mandrel requirements for TIA
standards.
Figure 5 shows how to wrap the fiber around a mandrel.
Place mandrels on the tester’s output fibers, as shown in
Figures 8 through 15.
In the reference and test connection diagrams shown on
the tester, mandrels are indicated by a loop in the fiber.
