These findings show XKL’s DarkStar® optical transport systems achieve the fastest latency available today. Unlike typical fiber test beds that recirculate a loop of 100km of fiber, XKL runs its tests on the complete route distance of fiber, inclusive of equipment.  As a result, XKL brings the field into its lab to evaluate fiber imperfections and simulate worst-case conditions  commonly experienced in the field.
