Subsea Cables & Internet Infrastructure

Although most subsea cables with Singapore POPs land at Singapore, some do not, and these exceptions are the keys to better uptime for your Layer 1 network. Five fibre pair AAE1 lands at a Penang, Malaysia CLS that has a fully diverse fibre ring for automatic route protection into Singapore. Each side of the fibre ring uses a separate bridge to cross the Malaysian/Singapore border. One side of the ring terminates at the older of the two Global Switch data centers and the other at SG3. So AAE1 neither lands at Singapore nor uses any of the Singapore cable landing stations. This is one reason why AAE1 is a 'must' for network capacity buyers. Other reasons include low latency for the Marseille/Singapore end points and relatively good pricing due to the system's high capacity. Bay of Bengal Gateway also lands in Penang, Malaysia, but my understanding is that it and AAE1 use different cable landing stations. However, I have not seen backhaul maps so I cannot clai...

Building a resilient Layer 1 network where Singapore is a major POP is very difficult. Most subsea cables land in Singapore via designated sea lanes with four to five cables per lane. This increases the risk of a dragged anchor taking many cables. Although over the last ten years there have been few or none such incidents, a network planner is judged on future performance and proper risk management. Moreover, most subsea cables land at subsea cable landing stations (only 4 in total) serving many other cables. So dividing traffic among several cables is not good enough if resiliency is the goal.

A consortium consisting of TATA Communications, Lightstorm, Microsoft, and Singtel just announced a new 16 fibre pair subsea network tailored to serve the AI data center markets in Hyderabad, Singapore, and Kuala Lumpur. It includes two Indian landings, one in Southern Chennai and another at Machilipatnum, the latter being the shortest path to Hyderabad. Both Hyderabad and Lumpur host large numbers of data centers equipped with GPUs for rent to estimate AI large language models. Conversely, Singapore is a distribution point for estimated AI models. What is sometimes called AI inference. Both space and power in the city state are too limited and expensive for AI model estimation. Besides the Singapore and Indian landings, there will likely be a cable branch landing in the Malaysian province of Selangor, chosen because it is the shortest way to reach Kuala Lumpur. Public information on the new system is sparse, but it is also likely that cable will include be extended to Hyderabad and Ch...

Google announced today a $15 billion dollar infrastructure investment in India that includes a new cable landing station in Visakhapatnam (Vizag), a Mumbai to Perth subsea link, a cable connecting Vizag to Singapore via a Malaysian landing (like Bay of Bengal Gateway), a subsea network between Chennai and Vizag, and a major cable from Vizag to Capetown. Although hyperscalers are frequent targets of criticism, one cannot say they lack ambition. 😀 Google's connectivity investments aim to create seamless, high capacity cables connecting India to the US using new and physically diverse routes. 1. First cable from India's West Coast to Australia. 2. First Indian  cable to South Africa. 3. Creation of a third Indian subsea hub in Vizag to improve cable landing diversity. 4. A cable link between India's two East Coast subsea and telecom hubs. 5. India's second cable to reach Singapore via Malaysian overland routes. Remarks: 1. I think Sify is like to be the cable landing oper...

The private equity firm Cerberus has taken a majority equity stake in Datawave Networks, a Cyprus-based subsea cable developer. Datawave's key project is to deploy a linear 16 fibre pair spatial division multiplexing cable linking UAE, Oman, Mumbai, Chennai, Thailand, Indonesia, Malaysia, and Singapore. Datawave began this project in 2019 when the company was incorporated. But due to the increasing dominance of American Tech Giants, investors have been reluctant to fund private wholesale network operators. It is simply seen as too risky given lack of hyperscaler demand for leased subsea network capacity. Due to the Cerberus acquisition, SING is now fully funded with Subcom expected to complete the project in 2030. I believe part of what drove Cerberus' interest in this project was the Red Sea bottleneck. While building Marseille to Singapore would be viewed as too risky given the required capital, linking the new subsea cable hub of Oman to Singapore seems like a...

The Pacific and Southeast Asia have two major telecom hubs: Tokyo and Singapore. Tokyo's status reflects its importance as the capital of one of Asia's largest economies with huge trade and financial flows with the United States as well as a defense treaty. Tokyo dominates Japan like Paris does France. Singapore's emergence reflects Hong Kong's downfall due to the Chinese government's failure to honor its commitment to HK autonomy. China requires any political candidate for HK office to be approved by it. Hence every HK politician is de facto a Beijing puppet. Secondly, China's security laws allow the arrest of anyone criticizing the Chinese government. The collapse of HK's rule of law is illustrated by numerous arrests of anyone peacefully opposing the government. You can go to jail for wearing a T-shirt advocating HK independence. In contrast, Singapore is neutral in the geopolitical war between the US and China and its judges are independen...

The American tech giant is deploying a high capacity cable directly linking Thailand to Christmas Island, which in turn will be connected by two diverse cables to Australia. The new route is unusual as it goes around Indonesia to reach Thailand's slender West Coast leg as opposed to threading the Sundra Stait and traversing the very busy waters off Singapore and up the Bay of Thailand. I told an international development bank a few weeks ago that it would make sense to do such a landing in order to avoid the crowded and congested Thailand Bay. My idea was to link India's East Coast to Thailand via its slender Southern leg. It is always a good idea to avoid routes that are already heavily used by subsea cables to improve resiliency. In this case, it also avoids ship-infested waters that pose a high risk of subsea cable damage. This new project makes two things very clear. Google's subsea cable guys are looking to reduce their network's reliance on Singapore, which is th...

Might close my first 100G into India today. 🙂 I recommend focusing for the next six months on the India/Singapore roiute as Red Sea construction of IEX, 2Africa, and SWM6 is on hold due to the possibility of missile strikes. In contrast, IAX and Mist do not face these issues. I understand that both Marseille and Singapore are essential peering points, but Marseille/Mumbai is likely to be hell for the foreseeable future. Put your incremental effort where it earns the greatest incremental return. Today is it is Mumbai or Chennai to Singapore. I am always available to provide your advice and guidance on your hunt for a Great Deal. 😃 

SEA-H2X: A Mystery Player Among Subsea Cables This cable is very under the radar. Very few industry insiders ever mention it. Yet, it is not an insignificant project. The main 8 fibre pair trunk directly connects Singapore and Hong Kong. It uses branching units to extend the cable to Malaysia, Thailand, Philippines, and a free trade Chinese port city known as Hainan. Hauwei Marine built it with advanced branching units that include optical switching as well as flexible power distribution. The cable's design capacity is 180 Tbps. At 20 Tbps a pair, I suspect there is upside throughput potential.  Interestingly enough, it is an open cable system so each consortium member selects and buys their own submarine line termination gear which I assume includes the DWDM kit. This helps to some extent alleviate the concern that Chinese security agencies have compromised the system. But there are other ways of eavesdropping other than infiltrating the terminal gear even though that is the best ...
