Telstra will invest hundreds of millions of Australian dollars to ensure the leading position of the submarine network in the Asia-Pacific region
A few days ago, Telstra announced that it had signed two new investment agreements for the laying of an international submarine cable system. The laying of the submarine cable will enable the connection of Hong Kong and China to the west coast of the United States. In the first investment, Australian Telecom will work with its partners to lay Hong Kong-United States (HKA) submarine cables, of which Australia Telecom will provide 50% of its fiber-optic cable pairs.
At the same time, Australian Telecom will provide capacity investment for Pacific Optical Network (PLCN), which is used to connect Hong Kong with the United States. After the project is completed, it will achieve a network transfer rate of 6 TB per second.
Paul Abfalter, OTT's director of emerging markets and telecommunications, said that Hong Kong's arrival in the United States is one of the fastest growing global demand for capacity. The investment in these two new submarine cables will further increase the capacity of the line to further meet people's needs.
Meet the growing market demand to ensure smooth connection
Paul Abfalter introduced that Australian Telecom has seen tremendous growth opportunities in the area of Internet connectivity in Asia. At present, Asia has nearly half of the world's Internet consumers and generates tens of millions of new services every year.
With the ever-increasing scale of the cloud computing market and the ever-increasing amount of data used in people's daily lives, the capacity demand for submarine cable is growing at a rate of over 40% every year. China is the biggest driver of traffic growth in Asia. In November 2017, only on the day of the “Double 11” Shopping Festival, China’s IP network traffic grew by 25%.
The explosive growth in market demand has made new and expanded submarine networks an inevitable choice for submarine network operators.
The two submarine cables invested by Australia will not only meet the market's demand for transmission capacity, but will avoid the natural disaster-prone areas, thus providing Australian Telecom customers with more flexible and safe link options.
According to Paul Abfalter, the two new submarine cables will provide customers with a more direct route between Asia and the United States than the AGG submarine cable connecting Hong Kong, Guam and Hawaii and connecting Southeast Asia with the US West Coast. Due to the shorter distance, the delay will be lower.
This means that in the event of a natural disaster or a vessel hitting a submarine cable used by a customer, they can have more backup lines to choose from.
This has also been the direction of Australian Telecom's efforts. In the first half of 2017, Australian Telecom’s “uninterrupted” service enabled Australian Telecom to provide world-leading and reliable network availability for Hong Kong to Singapore, Japan to Hong Kong and other Asia's busiest submarine cable lines.
This network advantage also makes Australian Telecom a leader in programmable networks. Australia Telecom's programmable telecom network launched in May last year is the best example. By providing automated, near-real-time on-demand provisioning capabilities, consumer-based pricing, and new data insights on network usage, Telstra can help customers optimize IT and expand global markets.
Continuous investment to ensure the leading position in the submarine network in the Asia-Pacific region
Paul Abfalter said that the submarine network is a key component of Australia Telecom’s global growth strategy. It is also a major emerging cloud and content provider, global and regional mobile service providers, and Australia’s demand for connectivity across the Asia Pacific region. One of the important services provided by the company.
Australia Telecom plans to invest hundreds of millions of Australian dollars to increase network transmission capacity and maintain Australia Telecom’s leading position in the submarine network in the Asia Pacific region.
It is reported that apart from investing in the new submarine cable between Hong Kong and the west coast of the United States and the INDIGO submarine cable system connecting Australia, Singapore and Indonesia, Australian Telecom will continue to expand investment in submarine cable to consolidate Australia. Telecom's network leadership. This includes: Increased capacity investment from Australia to the United States, and will invest in ground networks in countries such as China, Taiwan, Japan, and the Philippines to consolidate Australia Telecom’s unique network leadership.
At present, Australian Telecom owns and operates Asia’s largest and most diversified submarine network, which provides about 30% of the total capacity of the area.
