KEYSIGHT N7781B Polarization Analyzer

Characterizing polarization properties of optical signals requires a fast polarization analyzer. The N7781B provides graphical representation of the State of Polarization (SOP) on the Poincar? Sphere and fast polarization logging.

KEYSIGHT N7782B PER-Analyzer

Alignment of polarization-maintaining fiber optic devices requires a PER-analyzer. Keysight?s N7782B has been designed for high speed and highly accurate testing of the polarization extinction ratio (PER) in PM fibers and devices.

KEYSIGHT N7783B Thermal Cycling Unit

Keysight?s Thermal Cycling Unit N7783B is fully controlled by the Keysight N7782B PER-Analyzer and allows accurate and repeatable temperature cycling of the fiber under test.

KEYSIGHT N7784B Polarization Controller

Optical characterization needs the control of the state of polarization (SOP) in various ways. The N7784B provides alignment and fast stabilization of polarization into polarization maintaining fiber or with respect to an external feedback.

KEYSIGHT N7785B Synchronous Scrambler

The N7785B provides fast SOP switching in response to internal or external triggering. This supports optical network simulations that often require switching of the signal SOP in a random way within a few microseconds.

KEYSIGHT N7786B Polarization Synthesizer

The N7786B includes internal SOP monitoring and feedback to determinately set and hold chosen states or sequences of polarization. Fast switching provides single-sweep spectral PDL measurements with the N7700A software.
