Introducing the HP E5574A Optical Loss Analyzer
What You Can Do With the OLA
• You can measure the optical power of any active optical device
connected to one of the optical heads.
• You can measure two optical powers simultaneously (which is
mandatory for comparing active or passive optical devices and
for measuring optical couplers).
• You can measure the polarization dependent characteristics of
the DUT, be that two-port devices or couplers.
• By connecting the sensor head to the optical input, you can
measure the backreflection of a DUT, called Return Loss.

The OLA Applications

The OLA applications include the following measurements:
Insertion Loss (IL)
You measure the power loss of passive optical components.
Polarization Dependent Loss (PDL)
You measure the maximal power fluctuation caused by the DUT's
sensitivity to changes in polarization.
Coupler Test
You measure the Coupling Ratio (CR), Splitting Ratio (SR),
Insertion Loss (IL), Excess Loss (EL), and Directivity (DIR) of
optical couplers.
Polarization Dependent Coupler Test
You measure the Polarization Dependent Coupling Ratio (PDCR),
Splitting Ratio (PDSR), Loss (PDL), and Excess Loss (PDEL) of
optical couplers.
PDL / Insertion Loss
You measure the Polarization Dependent Loss (PDL) and the
averaged Insertion Loss (IL avg) simultaneously.
