The invisible infrastructure of global connectivity

The PLCN (Pacific Light Cable Network) submarine cable is a trans-Pacific cable system that was intended to connect the USA directly to Hong Kong and was one of the first cable projects of its kind to become the focus of geopolitical discussions about data security and cable infrastructure. As a joint project between Google and the Chinese company Pacific Light Data Communication, PLCN became a symbol of the growing strategic importance of submarine cables in the area of conflict between economic interests and national security. Submarine cables such as PLCN form the invisible foundation of global data traffic, as over 99% of international data flows through them rather than through satellites or the cloud.

Route & connection

PLCN connects Los Angeles (USA) with Hong Kong as well as with the Philippines and Taiwan as additional landing points. While the direct connection to Hong Kong has not yet gone into operation for regulatory reasons, the sections to the Philippines and Taiwan are already in use. With a total length of around 12,800 kilometers, PLCN is one of the longer trans-Pacific cable systems and connects important economic areas in the Asia-Pacific region.

PLCN at a glance

What is the PLCN cable?

PLCN (Pacific Light Cable Network) is a trans-Pacific submarine cable with its main landing point in Los Angeles, US, and branches to Toucheng in Taiwan and Baler in the Philippines. The cable spans around 12,800 kilometers and reaches a design capacity of 144 Tbit/s across six fiber pairs. It was built by TE SubCom, and its owners are Google, Meta and the Hong Kong-based company Pacific Light Data Communication (PLDC). The originally planned direct connection between the US and Hong Kong was denied by the US regulator FCC on national security grounds and remains unconnected to this day. The sections to the Philippines and Taiwan operate independently of this.

Especially in a market environment where regulatory frameworks and geopolitical developments can directly influence the availability of cable capacities, an experienced partner with in-depth market knowledge is indispensable. This is precisely where SAVECALL comes in. We continuously monitor developments in the global cable market, analyze your connectivity strategy and source capacities on the available PLCN sections specifically for your requirements.

The result for our customers:

  • Direct capacity access on active PLCN sections without reseller chains
  • Transparent price benchmarking and market data
  • Strategic consulting in the context of geopolitical cable developments
  • Negotiation of IRU structures and leased capacity models
  • Clear SLAs and ongoing capacity management

PLCN compared

On the route to Taiwan and the Philippines, PLCN competes with other modern cable systems. For procurement decisions, what matters most is which landing points are needed and how a possible regulatory restriction on individual segments affects a company’s own redundancy concept. The comparison below positions PLCN against Jupiter, which also connects the Philippines, and FASTER, which also reaches Taiwan.

Vendor-neutral assessment: SAVECALL does not rank PLCN, Jupiter and FASTER against each other, but views them as complementary building blocks for resilient trans-Pacific connectivity. Which cable or combination makes sense for a business depends on the required landing points in Taiwan, the Philippines or Japan, as well as an assessment of regulatory risk on individual segments. As a carrier-neutral consultancy, we source capacity across all relevant systems and recommend purely based on actual requirements.

Frequently asked questions about the PLCN cable

Which countries does the PLCN cable connect?

PLCN connects Los Angeles in the US via active segments to Toucheng in Taiwan and Baler in the Philippines. The originally planned direct connection to Hong Kong was not approved by the US regulator FCC and is not in operation. For companies with sites in Taiwan or the Philippines, PLCN still offers a modern, high-capacity connection to the US.

How high is PLCN’s capacity?

PLCN reaches a design capacity of 144 Tbit/s, spread across six fiber pairs using C+L band technology. This makes it one of the highest-capacity trans-Pacific cables in the world, even though the Hong Kong segment cannot currently be used.

When did PLCN go live and who operates the cable?

The active US-Taiwan and US-Philippines segments of PLCN have been operating since 2022, after the original license for the Hong Kong connection was denied by the US regulator FCC in 2020 on national security grounds. The cable was built by TE SubCom, and its owners are Google, Meta and the Hong Kong-based company Pacific Light Data Communication (PLDC), though PLDC has no access to the disconnected Hong Kong segment.

PLCN, Jupiter or FASTER: which cable is right for my business?

This mainly depends on the landing points you need and how you assess regulatory risk. PLCN offers the highest capacity on the route to Taiwan and the Philippines, Jupiter additionally connects Japan directly with the Philippines, and FASTER offers a route to Japan and Taiwan that has been established since 2016. SAVECALL advises on the right combination for your requirements on a vendor-neutral basis.

How do I plan redundancy on the trans-Pacific route?

Genuine redundancy only exists when the chosen cables use different landing points, ownership structures and physically separate routes. For PLCN, companies should also factor the regulatory history of individual segments into their risk assessment. SAVECALL plans these concepts independently of any single cable operator, with a focus on actual failover reliability.

How do I get access to capacity on PLCN?

Access to capacity on the active PLCN segments runs through direct wholesale partnerships with Google and Meta, as well as IRU or leased capacity agreements. SAVECALL negotiates these structures directly, without detours via reseller chains, and factors in the regulatory framework as needed.
