Description
The
return
loss
range
species
the
range
of
reection
levels
that
can
be
measured.
Reections
that
are
larger
than
10
dB
,
for
example
5
dB
, may
be
inaccurate
due
to
receiver
saturation.
Reections
smaller
than
80
dB
,
for
example
85
dB
,
may
be
less
accurate
due
to
instrument
noise
oor
limitations
.
At
1550
nm,
the
80
dB
specication
applies
only
over the
0to
100
mm
mirror
position
range
with
dispersion
correction
enabled.
(Refer

Chapter
2
to
learn
how
to
enable
the
correction
data.)
The
measurement
range
is
degraded
due
to
dispersion
eects
over
the
100
mm
to
400
mm
range
.
