Introduction
The PMD5000 is a modular system for Jones Matrix Eigenanalysis based PMD/PDL measurements built onto the TXP platform. It is a powerful and flexible solution for all kinds of PMD/PDL related measurement tasks in laboratories as well as field applications including the analysis of installed fibers.

Modular Design
Depending on the application the PMD5000 System comprises different modules that can be used independently as well. The PMD5000 utilizes external tunable lasers as light source. We can integrate most tunable lasers with a PC interface. Drivers for the following models are readily available: Agilent Mainframe 8163A/B, 8164A/B, 8166A/B, and Module 81940A as well as Ando AQ4320A/B/D.

Analysis of Narrow Bandwidth Components
The software package version 2 for the Thorlabs PMD/PDL Analysis System PMD5000 series enhances its application especially for the analysis of narrow bandwidth components. The PMD5000 system, which is based on Jones Matrix Eigenanalysis, now allows the analyzing parameters to be changed after the device under test (DUT) has been measured. A single data set of the DUT can be analyzed for different wavelength ranges or at different zoom levels. This makes repetitive measurements with optimized parameters obsolete and contributes to speed and flexibility of the analysis. For more information please see the "User Interface" tab.

Besides a suitable external tunable laser source, the PMD5000 consists of the Deterministic Polarization Controller, DPC5500, and a polarimeter module - either the fast in-line polarimeter IPM5300 or the High Dynamic Range Terminating Polarimeter, PAX5720IR3 - plus a specific software package providing powerful PMD/PDL analysis routines. A test version of this is integrated into the TXP application software which can be found at the TXP Software tab on the TXP platform page. Please see the Components tab for the modules of the 4 standard PMD5000 Systems.

PMD5000 Series User Interface

The PMD5000 System offers a wide range of measurement data. The insertion loss (IL) and the polarization dependent loss (PDL) are displayed in a single graph. The differential group delay (DGD) versus wavelength is shown in another graph with an additional histogram. The phase difference between two Jones matrices is given in a third diagram. The second order PMD and therefore the second order DGD versus wavelength can also be measured and is displayed separately with a histogram. Another measurement is the principle state of polarization shown in a diagram in the form of Stokes parameters. All data are also available as numerical values.

The following figure shows the GUI of the measurement mode with the DGD graph.

The green vertical lines show the wavelength range for which the analyzed parameters are calculated (upper left "Calculations" pane). The blue vertical line shows a specific single wavelength (cursor) for which the parameters are calculated (lower left "Cursor" pane).

Both the wavelength range and the cursor wavelength can be set and changed after the actual measurement has been performed. This allows quick fine-tuning of the wavelength range of interest for the analysis without running a measurement again.
