O/E Module MN4765B OM PN: 10410-00742 Rev. H 3-7
Operation 3-3 O/E Measurements
The 3 dB bandwidth can be determined from the measurement using the
Anritsu VectorStar VNA; approximately 53 GHz in the Option 70 example
shown above in
Figure 3-3 on page 3-6 , and approximately 95 GHz in the
Option 110 example shown in Figure 3-4 below.
Phase linearity, group delay, and return loss of the O/E DUT can also be
extracted from this measurement setup. A characterized optical modulator is
also required for an O/E measurement.
