Subsea Cables & Internet Infrastructure

Candle is one of the more interesting Intra-Asian cables to go live over the next several years. It is the first 24 fibre pair system to serve this region. Total transmission capacity is 570 Tbps. This makes it one of the highest capacity cables on the planet. Like Apricot, Candle avoids the South China Sea due to Beijing's territorial claims and permitting demands. The main trunk links the inseparable couple of Tokyo and Singapore with branches into the Philippines, Taiwan, Indonesia, and Malaysia. Consortium leaders include META, Softbank, and Telekom Malaysia. This project, like Apricot, exemplifies the geopolitics of American-Chinese rivalry. Hyperscalers avoid China and HK and exchange traffic at neutral Singapore. However, the routing is shorter than Apricot because Candle is deployed at the edge of the South China Sea as opposed to a long detour around Indonesia and up the East Coast of the Philippines. Like Apricot, Candle offers physical diversity to the usual suspects mak...

Japan suffers from a lack of physical diversity in cable landings. For example, the Maruyama CLS serves 8 cables, most of them major Internet arteries including ASE, APG, Jupiter, TPE, and ADC. According to the Submarine Networks website the country has more than 20 facilities. However, they are densely concentrated as the map below shows. Moreover, it would not be surprising if many of the are sharing back haul fibre. Consequently, the Japanese government is giving money to Softbank for the construction of two new cable landing stations in the Hokkaido and Fukuoka projects because they make nations's telecommunications more robust The project's anchor tenant is the ETA (East to America) subsea cable.  In general I am skeptical of subsidies for a variety of very good reasons, namely they usually distort the allocation of resources in pursuit  of political gain. However, aid for new cable landings that are diverse to the existing landing infrastructure may be exception. It woul...
