APPLICATIONS
●●
● Recirculating loop experiments: - Loop-synchronous polarization scrambling System test: polarization sensitivity analysis on link / transmission quality Characterization of optical components The results obtained in re-circulating loop experiments depend heavily on the PMD and PDL properties of the loop. Loop synchronous polarization scrambling schemes have proven to be necessary for generating results comparable to deployed systems. The synchronized scrambling feature of the N7785B is a unique enhancement to conventional polarization scramblers. The polarization can be scanned according to a pseudo-random but reproducible path. Instead of a continuously changing SOP, the SOP is switched in discrete steps that are synchronized with an input or output trigger signal. After switching, a stable SOP is quickly reached and held until the next step. The N7785B is ideally suited to provide the synchronous scrambling capability in such experiments.
