1. A method comprising:
providing an optical fiber coiled about a bobbin at a first location in a wellbore in a subsurface formation, wherein a first end of the optical fiber is communicatively coupled to a data processing system;
pumping a first fluid through the wellbore during a cementing process, wherein a second end of the optical fiber is dragged through the wellbore via the pumped first fluid, wherein pumping the first fluid through the wellbore comprises pumping the first fluid into an annulus between a casing and a wall of the wellbore, and wherein the second end of the optical fiber is dragged into the annulus via the pumped first fluid; and
monitoring, with the data processing system, a first wellbore condition based on a signal transmitted via the optical fiber at least while the optical fiber is dragged through the wellbore.
