Cleaning Suggestions
Following
is
a
list
of
suggestions
for
cleaning
connectors,
ferrules,
and
bulkheads:
• Always
maintain
dust
caps
and
dust
plugs
installed
when
connectors
or
adapters
are
not
mated.
Store
spare
dust
caps
in
a
zip
‐
lock
bag
when
not
in
use.
• Avoid
allowing
unmated
connectors
to
touch
surrounding
unrelated
surfaces
and
do
not
touch
a
connector
or
bulkhead
ferrule
for
any
reason
other
than
while
performing
the
cleaning
process.
• Use
a
fiberscope
or
videoscope
to
verify
proper
cleaning
of
connectors
prior
to
mating
connecting
components
together.
• Use
an
appropriate
quality
fabric
type
cleaner
and
pure
alcohol
(reagent
grade,
99.5%
pure)
when
cleaning
the
endface
of
connectors.
The
alcohol
can
be
applied
with
either
laboratory
grade
lint
‐
free
tissues
or
with
pre
‐
moistened
optical
grade
wipes.
• Use
microporous
fabric
spiral
wrapped
cleaning
tips
to
clean
bulkhead
ferrules.
• Do
not
use
compressed
air
to
clean
optical
bulkheads.
Cleaning the Connectors
To
clean
the
connector,
complete
the
following
steps:
1. Wrap
the
cleaning
wipe
around
the
exposed
connector
endface,
apply
firm
pressure,
and
twist
the
wipe
around
the
ferrule
back
and
forth
in
quarter
to
half
‐
turn
rotations
at
least
three
times.
2. Press
the
endface
of
the
ferrule
directly
into
a
clean,
wet
spot
on
the
wipe
and
twist
the
ferrule
while
applying
pressure
to
perform
a
wiping
action.
3. Inspect
the
endface
of
the
ferrule
with
either
the
fiberscope
or
videoscope.
If
further
cleaning
is
warranted,
use
the
fabric
type
cleaner
to
continue
cleaning
according
to
the
cleaner
instructions.
Remember
an
angle
polished
connector
is
in
use
so
refer
to
that
specific
section
of
the
fabric
type
cleaner’s
instructions.
Cleaning the Bulkhead
To
clean
the
bulkhead,
complete
the
following
steps:
1. Remove
any
dust
caps
or
connectors
from
bulkhead.
2. Insert
a
new
fabric
spiral
wrapped
cleaning
tip
into
the
ferrule
of
the
bulkhead.
3. Using
your
fingers,
apply
a
firm
pressure
to
the
cleaner
as
you
twist
the
cleaner
handle
two
or
three
times
to
create
a
wiping
action
of
the
cleaning
tip
on
the
ferrule
endface.
4. Discard
the
cleaning
tip
after
using
on
a
bulkhead.
