Introducing the HP E5574A Optical Loss Analyzer
What You Can Do With the OLA
The OLA consists of
• one or two built-in Fabry-Perot laser sources,
• a 3-dB optical coupler for the connection of an external source
and for Return Loss measurements,
• a 4-paddle polarization controller for automatic sweep or manual
setting of the polarization,
• an optical output with either a FC/PC terminated fiber pigtail, or
a straight contact connector, or an angled contact connector,
• one or two optical heads, chosen to match wavelength and
sensitivity requirements,
• the signal processing and display unit.
1.2 What You Can Do With the OLA
As one can see from Figure 1-1, the OLA has one output and three
input ports. It therefore supports a variety of applications.
Operational Modes
You can set-up the OLA to perform as follows:
• It can serve as a highly stable source of linear polarized infra-red
light with a wavelength of 1310 nm and/or 1550 nm.
• It can launch its own or any light from an external source to any
optical device under test (DUT).
• It can circulate the optical output through all states of
polarization or establish any desired state of polarization.
• Once the source power has been measured and stored, you can
measure the Insertion Loss of any passive DUT, the output of
which is connected to one of the optical heads.
