Field Trial of a 4C Fiber Optic Seabed System

A29 FIELD TRIAL OF A 4C FIBER OPTIC SEABED SYSTEM SUMMARY 1 A fiber optic 4C seabed cable has been successfully demonstrated in the North Sea. The cable design and performance is reviewed. A 2400 m array length with 4C sensor stations located every 25 m was tested in a water depth of 300 m. The cable was tested in shallow water and is relatively short in seismic acquisition terms. However we have demonstrated in the lab the optical systems capabilities beyond 3000 m depth and 12 km array lengths with channel counts in excess of 2000. In the field
