System dynamic range Ratio of electrical powers, expressed
in dBe. The definition of system dynamic range depends on
the type of measurement:
O/O Difference between the electrical power in dBm
measured with
LCA optical in and the
electrical in)
applied to LCA optical in).
Measurement: after O/O setup calibration do a
measurement with darkened LCA optical in.
O/E Difference between the
power
in dBm and the receiver
(of LCA electrical in)
electrical in).
Condition: wavelength as specified.
Note: O/E system dynamic range is identical to E/E
system dynamic range.
E/O Difference between the electrical power in dBm
measured with the largest possible
power
at the LCA optical in, and the
floor (of LCA electrical in)
Conditions: maximum
LCA optical in as specified.
Note: The largest possible modulated optical power at
the LCA optical in is defined by the
operating input power (of LCA optical
Measurement:
1 Measure the
receiver (dB
electrical power (dBm) corresponding to the
Maximum linear operating input power (of LCA
optical
in).
2 Measure the electrical noise floor (dBm) with
darkened LCA optical in.
3 Calculate the difference between both (expressed in
dBe).
