Abstract : A considerable effort has been put into the characterization of the Contention Resolution Optics (CRO) preprototype during the eight quarter of the CORD project. Of primary concern is the instability of the optical signal polarization as it progresses through the CRO. A series of tests were conducted to pin down the source of the polarization instability. A demo unit from Hewlett Packard was received and has provided a much better insight into all of the polarization instability phenomena. Additional polarization controllers were installed. A conclusion was reached that the best way to re-assemble the CR0 in such a way that its operation be high-performance and stable for several hours was that of pervasively using short spans of polarizing fiber to connect the several different elements of the CRO.
