TOKYO, February 28, 2011 - NEC Corporation (NEC; TSE: 6701) and Pacnet today announced the signing of a multi-million dollar contract to upgrade the 9,620km EAC Pacific Cable Network (“EAC Pacific”) which represents two of the five fiber pairs of the Unity Cable System, connecting Chikura, Chiba, off the coast of Japan near Tokyo, to Los Angeles, California.
The PC-1 submarine cable system is owned and operated wholy by Pacific Crossing, an NTT Communications Corporation company. This trans-pacific submarine cable system PC-1 netowrk consists of 4 optical fiber pairs, uses the state-of-the-art technology for optical transmission and submarine cable system, forms protected network rings, connecting the U.S. and Japan. The 21,000km PC-1 submarine cable system offers the highest reliability and the lowest latency across the Pacific. Supported by extensive backhaul into major U.S. and Japanese cities, Pacific Crossing’s infrastructure offers seamless interconnection to virtually every major international network operator for onward global access. With PC-1 network, Pacific Crossing delivers state-of-the-art capacity and managed network services at competitive prices to a growing customer base of carriers and media and information transport-intensive enterprise customers. PC-1 offers protected trans-pacific capacity up to 10Gbps (SDH and wavelength), as well as Ethernet services up to 10G LAN PHY and 10G WAN PHY. The PC-1 network was upgraded with 100G coherent technology to offer 100GE connections from Japan to the USA in July 2013

On August 17, 2009, Magnitude 6.7 earthquake hit the east coast of Taiwan, after the spread of Typhoon Morakot on August 9, the deadliest typhoon to impact Taiwan in recorded history. Eight submarine cables were cut by the earthquake and landslides caused by the Typhoon Morakot.
In January-February 2008, multiple submarine cable cuts occured in the Persian Gulf and the Mediterranean regions. The cable cuts caused internet disruptions and slowdowns, affecting at least 60 million users in India, 12 million in Pakistan, six million in Egypt and 4.7 million in Saudi Arabia. The cable cuts called into doubt the safety of the undersea portion of the Internet cable system.
2011 March 11 05:46:23 UTC, A magnitude 8.9 earthquake struck off the northeastern coast of Japan (modified to magnitude 9.0 later), at 38.322°N, 142.369°E and 373 km (231 miles) NE of TOKYO. The earthquake and its aftershocks and the tsunami resulted in multiple submarine cable cuts that threatening much of the intra-Asia and trans-Pacific telecommunications.
AAG cable network forms a linear trans-Pacific route, spans 20,000km directly between the South East Asia and the USA, with trunk route between Malaysia and the USA via Hong Kong, the Philippines, Guam and Hawaii, with branches into Singapore, Thailand, Brunei Darussalam and Vietnam. AAG cable network offers the shortest latency between Hong Kong and the US west coast.
