General Information
The POF Cutter Block has been designed
exclusively for cutting plastic optical fiber. Do not
attempt to cut glass fiber.
Upon inspection of the fiber cutter you will find
seven holes or apertures as shown in Figure 1.
The apertures are precisely drilled holes for
optimal cutting of the most commonly used
plastic optical fibers. See Table 1 to determine
the proper aperture for the fiber you wish to cut. If you do not find the fiber listed, please
refer to the aperture sizes in Table 2. Choose the closest aperture size that exceeds the
overall diameter of the fiber.
To eliminate a step when working with jacketed duplex fiber, the cutter splits the jacket at
the midpoint when it is pushed into the cutter. To split a 1000 μm core jacketed fiber, insert
the fiber into apertures 4a and 4b when following the instructions in the next section.
Splitting and cutting the fiber this way ensures that both fiber ends are the same length for
a professional and easy-to-use termination.

Fiber Cutting Procedure
To cut fiber with this cutter please complete the following steps:
Select the correct aperture for the fiber being cut.
Pull up the razor blade.
Push fiber into the selected aperture until it extends 2 mm beyond
the razor blade.
Press down on the top of the razor blade until the fiber is cut through.
Pull up the razor blade and remove fiber.
Replacement Blades
The replacement blades for this cutter are the same
physical size as single-edge razor blades available at
most hardware stores. We recommend “Extra KEEN”
single-edge blades because they produce superior
terminations when cutting most fiber except the 3.0
mm core bare type. Our part number for the Extra
KEEN blade in packages of 100 is IF-FC1-RP1. For
the 3.0 mm bare fiber, we recommend standard-edge
blades. The replacement package of 100 standard
blades is our part number IF-FC1-RP2.
Standard edge blades last longer when cutting all fiber diameter, but do not produce as
smooth and defect-free fiber cuts.

Blade Replacement Procedure
To replace the fiber cutter blade complete the following steps:
Using a size 1 Phillips screwdriver remove the 2-56 screw.
Adjacent to the razor blade is a #2 wave washer. Remove the washer and dull
razor blade from the cutter body.
Dispose of the razor blade carefully.
Place a new single-edge razor blade and wave washer into the slot.
Align blade, wave washer and screw holes and then re-insert the 2-56 screw.
Tighten the 2-56 screw so a slight amount of friction is placed on the razor blade.
For longer blade life, rotate a worn blade 180 degrees and re-install. This places a new
portion of the blade into use in relationship to a particular aperture.
