Abstract
In some examples, multiple front-end device based high speed OTDR acquisition may include measuring, in parallel, light transmission with respect to specified optical fibers of a plurality of optical fibers by utilizing a plurality of analog and optic front-end devices. A front-end interlace may be operatively connected to the plurality of analog and optic front-end devices. The front-end interface may convert analog signals received from the specified analog and optic front-end devices to digital signals. A measurement controller may be operatively connected to the front-end interlace to control operation of the plurality of analog and optic front-end devices, and analyze, based on the digital signals, a property of the specified optical fibers.
