Setup
1.
Make
sure
that
cable
connector
,
detectors
and
adapters
are
clean.
2.
Connect
the
equipment
as
shown
in
Figure
D-1.
Ensure
that
the
cables
to
and
from
the
attenuator
are
xed
on
the
table
and
that
both
the
optical
head
and
the
DUT
are
close
together
so
that
minimum
cable
movement
is
required
when
connecting
the
cable
to
the
head
or
to
the
DUT
.

3.
Turn
the
instruments
on,
enable
the
laser
source
and
allow
the
instruments
to
warm
up
for
at
least
20
minutes
.
Note
The
linearity
test
must
only
be
performed
at
either
1300nm
or
1550nm.
The
accuracy
test
must
be
performed
in
the
-20dBm
range
at
10W
at
both
1300nm
and
1550nm.
