Zusammenfassung:	A system is provided which includes a bottomhole assembly, a cable assembly, and a controller. The bottomhole assembly is disposed in a wellbore traversing a subterranean formation from a surface of the earth, and includes a drill tool. The cable assembly includes a fiber optic line coupled with the bottomhole assembly. The fiber optic line has a length that traverses a length of the wellbore from the bottomhole assembly to the surface. The fiber optic line is a distributed sensor and measures one or more downhole parameters along the length of the fiber optic line during the drilling of the wellbore. The controller is coupled with the cable assembly, and receives data from the fiber optic line during the drilling of the wellbore by the drill tool.
