(Nasdaq: LVLT) today announced an agreement whereby Global Crossing Ltd. (Nasdaq: GBLX) will acquire a 50 percent ownership interest in the previously announced Level 3 transatlantic fiber optic cable now under construction. Level 3 also announced that it will acquire capacity on Global Crossing's transatlantic cable Atlantic Crossing 1 (AC 1). The four fiber pair, 1.28 terabit system -- announced by Level 3 in April 1999 -- is already under construction and has a scheduled in-service date of September 2000. Under the co-build agreement, Level 3 and Global Crossing will each separately own and operate two of the four fiber pairs on this transatlantic cable. Landing stations are on Long Island in the United States and on the West Coast of the United Kingdom. The cable will use advanced optical transmission technology to maximize capacity. Level 3 is managing the construction of the cable. Level 3's two fiber pairs will continue to be called Project Yellow. In addition, Level 3 will acquire capacity on Global Crossing's AC 1. This AC 1 capacity will enable Level 3 to offer protected services and develop its meshed network architecture across the Atlantic. Global Crossing's two fiber pairs will be called Atlantic Crossing 2, or AC-2, a system announced in March 1999 to provide double-redundancy across the highly trafficked Atlantic corridor, and will be fully integrated with the Global Crossing Network.
