Operating Instructions
Introduction
The Wilcom OFI Model F6222C Probe is a rugged, hand-held, easy-to-use mainte-
nance and installation instrument that identifies optical fibers by detecting the opti-
cal signals that are transmitted through a singlemode fiber. The F6222C utilizes
non-destructive macro-bend detection, which eliminates the need to identify a fiber
by opening it at the splice point. Thus, the probability of interrupting service is
eliminated.
Signals that the F6222C detect include continuous wave live optical transmission,
and low frequency modulated tones at 270, 1000, and 2000 Hz. When the F6222C
detects traffic on a fiber being tested, one of two LEDs on the F6222C illuminates to
indicate the presence and direction of transmission. The presence of tone is indi-
cated by illumination of one of three LEDs (Figure 1). The relative level of core
power within the fiber is also displayed on the two-digit seven-segment LED dis-
play. The F6222C also has an easy to use thumb lock feature for hands-free opera-
tion
Operating the F6222C
Operation of the F6222C is simple, as outlined in the
following steps:
1. Choose an adapter head for the type of fiber to be tested.
The F6222C is supplied with three adapters (as shown in
Figure 2): (A)
foam-covered
, to accommodate 900 µm buff-
ered fiber; (B)
smooth-surfaced with foam perimeter
, for
use with ribbon fiber or a 250 µm coated fiber; and (C)
slot-
ted
, for 3 mm and
optional
2 mm jacketed fiber (i.e., pigtails
and jumpers) or loose tube fiber.
2. Select the appropriate adapter and slide it into the mating
slotted channel of the F6222C with slight downward pres-
sure, as shown in Figure 3.
3. Insert the fiber to be tested between the adapter and the top
of the clamp (refer to Figure 4). Slide the thumb switch
upward and ensure that the fiber is installed properly in the
alignment groove.
4. For
hands-free
operation, slide the thumb switch upward and
“rock” forward to lock, and the fiber will be held in place
( refer to
Figure 4
) “rock” backward to unlock.
