The present invention provides an optical fiber for connecting a probe head and a base station of a spectroscopic analysis system for analyzing the molecular composition of a volume of interest. The optical fiber comprises a core for transmission of excitation radiation from the base station to the probe head and a first cladding for transmission of multi-mode return radiation from the probe head to a spectroscopic analysis unit of the base station. Preferably, the first cladding is surrounded by a second cladding and therefore provides a multi-mode wave guide by itself. Appropriately designing the dimensions of the core, the first cladding and the second cladding provides an optimal collection and coupling efficiency of the optical fiber. Coating of the distal end facet of the optical fiber with multi-layer optical filters allows an effective separation of elastically and inelastically scattered radiation which is of advantage for the spectroscopic analysis.
