The development of the NOE calorimeter, based on scintillating fiber technology, has undergone four years of intense R&D activity. Measurements of light attenuation and time resolution have been carried out on a variety of commercially available scintillating fibers. Both these parameters are important for the optimization of the design of the NOE calorimeter. Experimental results on the fiber attenuation length and light yield make us confident on the possibility to build a 8x8m2 cross-section calorimeter without noticeable loss of signal. The time resolution is resulted to be of the order of 1ns, sufficient for up/down discrimination in the final calorimeter setup, by means of the time-of-flight method. Several tests performed to optimize the elementary cell of the calorimeter are also described.
