Launched in Q1 of 2013 in Hong Kong, the Asia Submarine-cable Express (ASE) links Hong Kong with major business hubs in East Asia including Japan, Singapore, the Philippines and Malaysia, providing the highest possible speed, capacity and reliability. ASE is the most dedicated network infrastructure NTT Communications has invested within Asia in recent years. It will have a total capacity of more than 15 Terabits per second (Tbps), equivalent to about 60 times of the total internet traffic in Hong Kong, and will deliver ultra-low latency connectivity in the region.

Below are a few highlights of The Making of ASE. To view more photographs as well as video, please visit the NTT Com Asia Facebook Fan Page (www.facebook.com/nttca).

Asia Submarine-cable Express – Works Commencement in Hong Kong

A crane armed with a huge claw over 2.5m high was required to assist with the preparation of the sea wall to welcome the arrival of ultra-low latency network – Asia Submarine-cable Express in Hong Kong. On 4 October 2012, the crane gently lifted the first rock off the shoreline near the FDC™ in Tseung Kwan O, where the landing station is located. Rocks were temporarily removed from the sea wall to prepare for the cable. They will be returned to the original position as soon as the work completed. NTT Com Asia Facebook Fan Page To minimize the potential impact on local marina, the coastal work site was cordoned off before rocks under the sea were temporarily removed. The cranes claw was operated with controlled precision to mitigate the potential impact of the civil work on the marina.

Asia Submarine-cable Express – Cable-laying in Hong Kong Waters

On 6 October 2012, a barge was deployed offshore, at Tseung Kwan O for the cable laying works. The optical fiber submarine cable was coiled neatly on the barge for installation. This cable will be laid from Tseung Kwan O all the way through Tathong Channel into the South China Sea. A birds’ eye view of the submarine cable which will be stretched into Hong Kong Waters. The prototype of Asia Submarine-cable Express featuring double-armoured exterior for extra protection is pictured alongside the real cable. The buoys attached to the submarine cable mark the path to the shoreline of Tseung Kwan O. The cable burying machine was lifted into the sea and will be used for laying cables in deep sea. Computerized equipment on the barge will be used to monitor work in real time. Cable-laying in progress.

Asia Submarine-cable Express – Cable Landing in Tseung Kwan O

Divers check and locate the submarine cable in the sea before its landing onshore. Buoys were used to mark the path of the Asia Submarine-cable Express towards Tseung Kwan O shoreline. The submarine cable was pulled through a duct into the beach man hole. The Asia Submarine-cable Express required as many as eight powerful crewmen to assist on its landing. Once landed, the optical fibers of the submarine-cable system have to put to tests. To make it possible, it requires the removal of all the exteriors, including the double layers high tensile steel strands. The insulation layer was also carefully removed. The copper sheath was then unwrapped. Initial connection test on the optical fibers was conducted after landing.
