N7786B

Agilent N7786B Polarization Synthesizer Data Sheet SOP switching occurs within a few microseconds. An electrical trigger input can be used to synchronize the scrambler with external events. As an SOP switch , the N7786B cycles through a sequence of SOPs with a speed of more than 40 KHz, which corresponds to a cycle time of less than 25 microseconds. The sequence of SOPs can easily be defined by the user using Stokes coefficients. Figure 1. N7786B Bench-top Instrument Introduction The Agilent N7786B contains a high-speed LithiumNiobate based polarization controller and a polarization analyzer plus a microcontroller-based driving circuitry. This unit can operate in various modes: As a polarization stabilizer, it provides a stable output state of polarization (SOP) even with fluctuations and drifts of the input SOP. The stabilized output signal is guided in a standard single-mode fiber (SMF). The output SOP can be defined in the following ways: ● Set-and-forget: When the front button is pushed, the current SOP is stored and maintained, even if polarization changes occur on the instrument input. ● Defined stokes: The target output SOP can be defined by the user using the Stokes parameters. ● As a synchronous scrambler, the device switches www.DataSheet4U.com the SOP of the output signal in a random (pseudo) way with a cycling speed of up to 100 KSOPs/s. As a traditional scrambler, the N7786B varies the output SOP in a random way. Full coverage of the Poincaré Sphere is achieve...
