Fresnel
calibration
standard
The
free
end
of
the
TEST
PORT
cable
serves
as
the
\Fresnel"
calibration
standard. When
using
the
supplied
cables,
the
free
end
of
the
cable
functions
as
the
calibration
standard. This
is possible
because
the
percentage
of
light
reected
b
y
that
type of
cable connector
is known.
For
1300
nm
measurements,
the
correct
value
is
15
dB
(3.16%).
F
or
1550
nm, the
correct value
is 14.7
dB
(3.37%).
Other
calibration
standards
(cables,
connectors,
or
devices)
ma
y
have
other reection
values.
