Testing 2mm/3mm Jacketed Fibers with OFI 200

The following procedure may be used for testing 2mm/3mm jacketed fiber cables.

Note: 

It  is  important  to  place  the 

plunger in the correct position. Please 
refer to the illustration to the right. 
1  Remove the plunger cover.
2  Make sure the plunger is oriented 

as  shown  in  the  illustration.  If 
not, lift the plunger from the two 
retaining pins.

3  Rotate  the  plunger  such  that 

the  wide  groove  ( labeled 
“2mm/3mm”) is facing out and 
will  be  used  for  aligning  the 
fiber.

4  Replace the plunger and plunger 

cover.

5  Select the fiber to be tested.
6  Gently insert the fiber being tested into the fiber groove at the top of the OFI 200 head (refer 

to Figure 2-1).
