Independent fiber-optic reference apparatuses and methods thereof

Abstract

A reference management apparatus includes a reference signal housing, a fixed length propagation device, an oscillator device, and a reference management computing device. The reference signal housing having a propagation signal output and a propagation signal input. The fixed length propagation device is coupled between the propagation signal output and the propagation signal input. The reference signal management computing device is coupled to the oscillator device and the propagation signal input. The reference signal management computing device also comprises at least one of configurable hardware logic configured to implement or a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to: detect a start and an end of a transmission of at least one pulse signal through the fixed length propagation device; measure propagation time of the at least one pulse signal through the fixed length propagation device; and utilize the measured propagation time for managing a reference signal.
