the
ferrule
of
a
patchcord

an
adapter
,
make
sure
that
the
ber
end
does
not
touch
the
outside
of
the
mating
connector
or

Otherwise
you
will
rub
the
ber
end

an
unsuitable
surface
,
producing
scratches
and
dirt
deposits
on
the
surface
of
your

the
dust

back
on,
or
close
the

Keep
the

on
the

always
when
