of these magnets alternates, and can most easily be determined by a rod-shaped magnet that is easy to hold
between two fingers.
6.4. Stripping the Fiber
The fiber end should be stripped down to the cladding over a sufficient length to allow for the desired post cleave
length plus the discard length. The discard length should ideally allow for full clamping in the FHB, and should
therefore be 1.8″ (45 mm). A Ruler Block is provided for accurate positioning of the strip interface relative to the
cleave point. The fiber must be stripped down to bare glass and thoroughly cleaned at the location where the
diamond blade strikes the fiber (the cleave point).

6.5. Loading the Fiber
To load the fiber for cleaving:
1. Make sure that the correct Cleave File (Fiber File) and/or process parameters are selected for the fiber to
be cleaved (see Section 7.4). If necessary, the critical parameters can be estimated using the Auto
Parameter Tool in the Handset Controller.
2. If the FHB lids are closed, loosen the thumbscrews, press the lifting levers down to release the clamping
force and open the lids.
3. Check that the correct FHB inserts (top and bottom) are installed and that they are free from fiber and/or
coating debris. Position the fiber in the left-hand FHB V-groove with the stripped (discard) end positioned
in the right-hand V-groove.
