We present a detailed 2-850um SED study of a representative sample of the FIRBACK 170um population. These galaxies constitute the brightest ~10% of the contributors to the Cosmic Infrared Background. Their characterization is therefore crucial for constraining galaxy evolution models. Previous studies suggest that the sample spans z~0-1 and LIR~1010-1012Lsun. In this paper, we have combined archival Spitzer Space Telescope IRAC and MIPS data with our previous observations including deep K-band imaging, SCUBA, ISO, and VLA. This unprecedented spectral coverage allows us to discuss both the properties of individual sources, and the statistical properties of the sample.
