The paper reports on spectroscopic studies of the interaction of high-current Plasma-Focus (PF) discharges with a CD2 100-{mu}m-fiber within the PF-1000 facility operated at 600-650 kJ. Visible radiation (VR) spectra were recorded with a MECHELLE registered 900 spectrometer at different instants. The exposition was varied from 100 ns to 200 {mu}s. Hydrogen- or deuterium- and carbon-ion-lines were identified. The electron concentration of the core, as estimated from the Stark broadening of the CII-CIV lines, was above 1019 cm-13. From the intensity ratio of carbon-ion lines (CIII/CII and CIV/CIII) it was estimated that the electron temperature of the core was above 5 eV. For deuterium shots it was observed that the CD2-fiber induced a decrease in the neutron yield (to about 1010), but the obtained spectroscopic data are of interest for understanding of the physical processes.
