hand-held ribbon fiber identifier
Operating Instructions
Introduction
The Wilcom Model F6121R
Ribbon Fiber Identifier
is a rugged, hand-held,
easy-to-use maintenance and installation instrument that identifies optical
fibers by detecting the optical signals that are transmitted through a ribbon
fiber. Check for signal presence before re-routing or maintenance, perform
continuity tests and check cable labeling. This ribbon fiber identifier uses a
safe macrobending technique that does not disrupt traffic. At the same time,
it avoids damaging or overstressing the fiber Thus, the probability of inter-
rupting service is eliminated.
Signals that the F6121R detect include continuous signal optical transmis-
sion, and low frequency modulated tones at 270, 1000, and 2000 Hz. When
the F6121R detects traffic on a fiber being tested, one of two Traffic LEDs
on the F6121R illuminates to indicate the presence and direction of trans-
mission. The presence of tone is indicated by illumination of one of three
Tone LEDs (
Figure 1
). The F6121R also has an easy to use thumb lock
feature for hands-free operation.
Operating the F6121R
Operation of the F6121R is simple, as outlined in the
following steps:
1. Choose the correct adapter head for the type of ribbon fiber to be
tested. The F6121R is supplied with three adapters, each with
an
indexing notch
which is part of the ambient light reduction
design as shown in
Figure 2
:
(
A)
deep-slot
, for 3 mm jacketed fiber (i.e., pigtails and jumpers)
or loose tube fiber.
(B)
slotted
, to accommodate jacketed ribbon
fiber up to 12 count;
(C)
shallow-slot
, to accommodate bare
ribbon fiber up to 12 count;
2. Select the appropriate ribbon fiber adapter and slide it into the
mating slotted channel with slight downward pressure. Be sure to
place the adapter with the
indexing notch
facing the front of the
F6121R 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 fully 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.
