Abstract: An optical fiber module is provided and includes an optical fiber structure, a light-absorbing area and a photoelectric sensor in a housing. The optical fiber structure collectively arranges a plurality of first optical fibers to form at least one optical fiber bundle with a tapered end, and a second optical fiber is connected to the tapered end of the optical fiber bundle to converge the optical fiber bundle to the second optical fiber. The light-absorbing area corresponds to an end of the second optical fiber, such that the light-absorbing area absorbs scattering signals escaped and scattered when signals are transmitted from the plurality of first optical fibers to the second optical fiber. The photoelectric sensor is arranged corresponding to the plurality of first optical fibers to receive target signals escaped and refracted when the signals are transmitted from the second optical fiber to the plurality of first optical fibers.
