Polarization Controller

8169A - Keysight Technologies

The 8169A Polarization Controller, with single-mode fiber input and output, is used to change light from any polarized or unpolarized light source into any well-defined state of polarization. The design based on bulk-optic zero-order waveplates and a high-performance linear polarizer at the input provides optimum determination and repeatability of polarization states over a wide wavelength range. The 8169A is especially well suited for use together with a tunable laser to make swept-wavelength measurements of the polarization dependence of fiberoptic devices, by setting a set of relatively orthogonal polarization states for Mueller Matrix analysis. These measurements are supported by a Plug&Play driver and coordinated operation of the 8169A with a Keysight tunable laser and power meters can be enhanced with the Photonic Foundations Library software package. The fundamental basis of this flexible instrument also supports many general applications requiring polarization control and analysis.

Thermal Cycling Unit

N7783B - Keysight Technologies

Keysight's Thermal Cycling Unit N7783B is fully controlled by the Keysight N7782B PER-Analyzer and allows accurate and repeatable cycling of the temperature of the fiber under test. The PER measurement system consisting of the Keysight N7782B and the Keysight N7783B shows excellent accuracy and repeatability. Ease of use and automation interfaces, such as analog output ports for active alignment, make it particularly useful for production environments.

Multiport Power Meters

Keysight Technologies

The N77-Cs have a family-wide, common trigger concept, and a modern, browser-accessible user interface, making it convenient to configure the instrument’s functionality. High-speed measurement data acquisition, faster data interfaces, the use of dual-ported RAM for uninterrupted simultaneous measurement and readout, and fast power range switching help avoid unnecessary delays in the measurement process as well as in post-processing.
