The Keysight 81577A features excellent wavelength flatness and can handle high input power levels. Additionally, the 81577A features a power control to set the output power level of the attenuator.

The Keysight 81578A is designed for 50um and 62.5um multimode fiber applications. It features excellent wavelength flatness and can handle input power levels up to +27dBm.

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.

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

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.

Discontinued Head Adapter

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.

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.

The optical component analyzer combines polarization control with a polarimeter to measure polarization mode dispersion (PMD) or differential group delay (DGD), PDL and IL of optical components.
