Measurement: Zero output is created by the following:
• for O/E: the LCA electrical in port is terminated with 50
Ohm load.
• for E/O: the LCA electrical out is terminated with 50 Ohm
load, LCA optical in is darkened.
• for O/O: the LCA optical in is darkened.
The average is calculated within frequency sections of 1/10
of the specified system bandwidth. The result must be in
limit in each section.
Modulated optical power The amplitude of a harmonic optical
power modulation. The modulated optical power is calculated

Modulated optical power divided by average optical power is a value
between 0 (no modulation) and 1 (maximum modulation).
Optical noise floor (LCA optical in) The optical equivalent (see

in dBm.
The optical equivalent depends on the
