The Asia Pacific Gateway has connectivity points with two major international submarine cable systems
NTT Communications Corporation (NTT Com), the ICT solutions and international communications business owned by Japanese group NTT, has launched the Asia Pacific Gateway (APG), a high-bandwidth optical submarine cable network with connectivity points across the Asia region.
NTT Com has implemented the new gateway in partnership with major telecommunication operators in each country. The new fiber infrastructure will increase data transmission capacity in the Asian region, improve connectivity between various regions and countries and improve redundancy by means of diverse routing.
The new APG network has a total length of 10,400 kilometers, and leverages 100 Gbps optical transmission capabilities to deliver a capacity of more than 54 Tbps. The cable system, which avoids areas prone to earthquakes and typhoons, has connectivity points in mainland China, Hong Kong, Taiwan, Japan, Korea, Malaysia, Singapore, Thailand and Vietnam.
NTT Com has also established two diverse landing points in Japan for the APG and Pacific Crossing-1 (PC-1) submarine cable which connects between Japan and the United States. The Japanese company has also implemented diverse landing points in Hong Kong and Singapore for the APG and for the Asia Submarine-Cable Express (ASE), which was launched in August 2012.
NTT Communications provides consultancy, architecture, security and cloud services for enterprises.
China Unicom trials G.metro technology in Beijing
In related news, Chinese telecommunications operator China Unicom has carried out a field trial of German firm ADVA Optical Networking’s prototype G.metro (WDM-PON) technology in a fronthaul network.
ADVA Optical Networking said that the prototype uses a single bidirectional fiber link between head-end and tail-end equipment, reducing the requirement for wavelength configuration and management.
The German company also said that this technique reduces cost and complexity for metro access network applications, including mobile fronthaul/backhaul, fixed broadband access and enterprise networks.
After evaluating ADVA Optical Networking’s G.metro technology, China Unicom showcased the device to customers at a laboratory demonstration in Beijing.
“Due to booming demand for mobile data, it’s become essential that we find innovative ways to increase capacity. Converged metro-access networks are key to this, but so are reducing complexity and improving operational efficiency,” China Unicom network technology research institute director Guangquan Wang said.
