The Agilent 11896A Polarization Controller Measures very low PDL. The Agilent 11896A motorized polarization controller adjusts polarization and not power. It¿s optical fiber loop design provides all states of polarization with extremely small optical insertion loss variations (±0.002 dB) over a wide spectral range (980 nm and 1250 to 1640 nm.) This performance combination maximizes measurement accuracy for power sensitive applications, such as polarization dependent loss and gain, because the measurement uncertainty contributed by the polarization controller is minimized. The 11896A provides fast measurements of DWDM components with a rotation rate of 360° in <0.5 seconds.
Key Features
- Single-wavelength polarization-dependent loss measurement w/ Agilent 8163A/64A/66A or 8509C (2 to 10 seconds typical measurement time for PDL < 1.0 dB)
- polarization-dependent loss measurement (w/ Agilent 8153A and 8168XX)
- Polarization-dependent gain measurements of EDFA
- Polarization nulling for EDFA characterization
- Polarization sensitivity measurements of optical coupling factor (power delta vs SOP)
- Polarized beam alignment relative to principal polarization states of the test device (w/ Agilent 8153A)
- Polarization adjustment of optical launch conditions for polarization mode dispersion measurements
