Keysight’s Thermal Cycling Unit N7783A is fully controlled by the Keysight N7782A PER-Analyzer and allows accurate and repeatable cycling of the temperature of the fiber under test. The PER measurement system consisting of the Keysight N7782A and the Keysight N7783A 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.

Application:

Splice Angle Characterization

For characterizing an optical connection between two polarization maintaining fibers (PMFs), such as an optical splice, two thermal cycling units (Keysight N7783A) can be used. This eliminates the influence of input polarization or subsequent fibers at the output and isolates the angular misalignment of the connection located between the two thermal cycling units.
