Abstract

An optical fiber coil for a fiber-optic measuring device and a method for producing it. An opitcal fiber is applied to a winding body in a quadrupole winding pattern in directly successive winding layers such that the turns of the individual winding layers have, at irregular spacings, as large a number of crossover points as possible. The spacings between the individual turns in each winding layer are variable, but, on average, they correspond to approximately half the diameter of the optical fiber. The optical fiber coil is preferably applied to the winding body without the use of fixing and buffer means.
