Cleaning
Connections
for
Accurate
Measure-
ments
A
ccurate
and
repeatable
measurements
require
clean
connections
.
Use
the
following
guidelines to
achieve
the
best
possible
performance
when
making
measurements
on a
ber-optic
system:

K
eep
connectors
covered
when
not
in
use
.

Use
dry
connections
whenever
possible
.

Use
the
cleaning
methods
described
in
this
section.

Use
care
in
handling
all
ber-optic
connectors
.
 When
inserting
a
ber-optic
connector
into
a
front-panel
adapter
,
make
sure that
the
ber
end
does
not
touch
the
outside
of
the
mating
connector
or adapter
.
Because
of
the
small
size
of
cores
used
in
optical
bers
,
care
must
be
used to
ensure
good
connections
.
P
oor
connections
result
from
core
misalignment,
air
gaps
,
damaged
ber
ends
,
contamination,
and
improper
use
and
removal
of
index-matching
compounds
.
Use
dry
connections
.
Dry
connectors
are
easier
to
clean
and
to
keep
clean.
Dry
connections
can
be
used
with
physically
contacting
connectors
(for
example
,
Diamond
HMS-10/HP
,
FC/PC,
DIN,
and
ST).
If a
dry connection
has
40
dB
return
loss
or
better
,
making
awet
connection will
probably
not
improve
(and
can
degrade)
performance
.

Agilent
Technologies
strongly recommends
that index
matching
compounds
NOT
be applied
to their
instruments and
accessories.
Some
compounds
,
such
as
gels,
may be
dicult to
remove and
can
contain
damaging
particulates
.
If
you
think the
use of
such compounds
is necessary
,
refer
to
the
compound
manufacturer
for
information
on application
and cleaning
procedures.
