size reduced variation of the OCCSC3xx series. The latest submarine cable structure is called OCC-SC520, SC530 and SC540 in which the 3-Divided steel segments size was optimized to allow for more fibers that can be inserted in the submarine cables. Also, we will be able to se-
lect the cable design depends on the various system requirements (Capacity, Length, Power Feeding Voltage and etc…). The structure change from tightunit to loose tube design was very important for cabling the large effective area fibers. The OCC-SC3xx
and SC5xx series, loose tube design submarine cable, optical fibers are loosely packed with minimum stress. This innovation in our cable manufacturing process has some advantages, especially for cabling large effective area fibers because of the inner space availability within the 3-Divided steel segments that allows cabling optical fibers with almost zero stress.

The development towards higher bit rate optical communication systems has been rapidly evolving in recent years and the advances in transmission technologies have increased the level of requirements for each element of the system. For high capacity long haul submarine transmission systems, the deployment of “Ultra Low Loss” and “Ultra Large Effective Area” fibers have be-
