Description: The Agilent 8509C lightwave polarization analyzer offers high-speed, calibrated polarization measurements of both optical signals and components. These capabilities are provided by innovations in hardware, software, and applications of Jones matrix and Stokes vector mathematics.
The 8509C analyzer facilitates a greater understanding of the polarization properties of lightwave signals and materials in helping to develop higher performance lightwave components and systems, as well as more effective test and manufacturing processes. These developments involve many types of polarization-sensitive devices which are used in communications, sensors, optical computing and material analysis; devices such as single-mode fibers, polarization maintaining fibers, isolators, optical switches, lasers, beamsplitters, modulators, interferometers, retardation plates and, of course, polarizers and polarization adjusters.
Polarization characteristics affect all lightwave transmissions. The polarization of a lightwave signal is defined by its E-field components. As a signal propagates, interaction with optical components and other lightwave signals (in interfero-metric applications) modifies the magnitude and phase of the signal’s E-field components. Polarization-dependent loss, gain or even signal distortion may occur depending on the application.
Polarization mode dispersion (PMD) is a key hurdle limiting the transmission of signals at 10 Gbit/s and above. The Agilent 8509C lightwave polarization analyzer in conjunction with the Agilent 8164 series tunable laser source or the Agilent 8168 laser can be used to measure PMD of fiber and components down to 1 fs resolution.
This unit has the following features:
Measurement Capabilities: Polarization Mode Dispersion (PMD), Polarization Dependent Loss (PDL), Polarization Maintaining Fiber
(PMF) launch alignment (polarization cross talk), Degree of Polarization (DOP), Stokes Parameters and Average power measurements
Wide wavelength range: 1280-1640 nm S, C and L band coverage
Polarization Mode Dispersion accuracy: +/- 0.05ps (50fs)
Polarization Mode Dispersion measurement range: 0.01 ps (10 fs) to 400 ps. Measure very low PMD using the highly accurate Jones
Matrix Eigenanalysis (JME) method. PMD measurements can also be made using the Fixed Analyzer (or wavelength scanning) method
Wide dynamic range: +10 dBm to –55 dBm
High-speed measurements: Polarization measurement rate of > 3500 points per second
Operation Verification: An automated internal process that allows the customer to check the basic functions of the analyzer in order to
obtain the highest possible accuracy in PMD measurements
PMD Statistics: PMD statistics window allows viewing of PMD statistics. A Maxwell curve is automatically fitted to the data and the
parameters that define the shape of the fitted Maxwell curve is displayed
Low PDL measurements: 0.05 dB. PDL measurement using JME and power max-min methods
1 pm relative wavelength accuracy (with Agilent 86120C wavelength meter) - It allows very precise characterization of optical components
and fiber for chromatic dispersion
0.1 pm wavelength resolution - The best resolution on the market. This allows for optical fiber and component manufacturers to measure
their devices with very small step sizes
Easy PMD measurements of optical fiber and components - large measurement dynamic range. Ability to measure very small dispersion
values
