Asia Pacific Gateway Cable Designed for 54.8 Tbps

A consortium of communications companies, including NTT Communications, KT, Chunghwa Telecom, and others, has selected NEC to construct the Asia Pacific Gateway (APG) system, a high-bandwidth optical submarine cable system that will link 9 countries and territories in Asia. The signing took place at Beijing.


The APG system is designed for a transmission speed of 40 Gbps per wavelength, utilizing the latest Digital Coherent detection and OADM (Optical Add-Drop Multiplexing) technologies. It will be upgradeable to 100G wavelengths for a total design capacity of 54.8 terabits per second.


Asia Pacific Gateway Cable will have a length of 10,400km, linking China Mainland, Hong Kong, Japan, South Korea, Malaysia, Taiwan, Thailand, Vietnam and Singapore. APG is expected to meet the demand for intra-Asia connectivity between South East Asia and North Asia. Project completion is expected by June 2014. http://www.nec.com
