Japan-US Submarine Cable System or Japan-US Cable Network (Japan-US CN, J-US ) is the first high capacity trans-pacific subsea cable system using DWDM technology of 10 Gbps per wavelength. Japan-US Submarine Cable System consists of four fiber pairs, each operating at 10 Gbps DWDM, with design capacity of 640 Gbit/s (4,096 STM-1's), the equivalent of 7,741,440 simultaneous voice calls, making it the largest capacity cable in the Pacific Region. Initially, the system operated at 80 Gbit/s (512 STM-1's) with two lit fiber pairs, expanding to 400 Gbps (2,560 STM-1's) in mid 2001 by lighting the two remaining fiber pairs each with 16 wavelengths at 10 Gbps per wavelength, further upgraded to 32x10 Gbps DWDM in 2008. In June 2012, Japan-US CN consortium selected Ciena to upgrade with 100G technology.
