What is the global submarine cable industry thinking about right now? What are the key debates and headlines to know across the subsea landscape?
These are some of the questions Submarine Networks World attendees are asking as they gear up for the conference in Singapore—and we have all the info you need to know before you go.
Quick info on Submarine Networks World 2026
Submarine Networkss World is happening September 23-24 at the Sands Expo and Convention Centre in Singapore. This is one of the world’s largest gatherings of the global subsea communications community, offering a subsea-specific platform to exchange knowledge, explore the latest projects, develop strategies and form new partnerships to continue keeping the world connected.
There is a lot of interesting presentations on the agenda, but you won’t want to miss TeleGeography Research Director Alan Mauldin‘s keynote on September 23rd at 9:10 a.m. titled “Paradox: The Hidden Logic Behind the Submarine Cable Industry.”

We have a few quick suggestions to gear up for this event:
Few telecommunications industry trends have been as impactful in the past decade as the rise of content providers as the dominant users of international capacity. We’ve posted submarine cables owned by content providers for nearly a decade. When we first published this list in 2017, we had 20 cables listed. Fast-forward to today, and our list has grown to over 60—a sizable markup. Take a look at the list.
Traditional shared wavelengths can struggle to keep pace with increasing traffic volumes, yet building a private dark fiber network from scratch is a logistical nightmare with significant operational overhead. To solve this, wholesale providers have introduced a “middle ground” option to the connectivity menu: MOFNs. (Managed Optical Fiber Networks, that is.)
Forecasting new and soon-to-be-retired submarine cables is notoriously challenging—yet as the backbone of intercontinental communications, countless industries need to make plans based on what’s happening under the sea at any given time.
We’re now tracking future cable activity with our new submarine cable forecasts. These forecasts cover 10 years and will be updated quarterly for all datasets.
The Strait of Hormuz is a crucial artery, not only for the transit of oil and cargo but also for the data flowing through submarine cables on the seafloor.Given recent hostilities, which have included damage to data centers in the UAE and Bahrain, it is worth considering whether the potential risk to telecommunications infrastructure extends to the submarine cables in the region. Here’s what you need to know about cables in the Strait of Hormuz and in the region.

A steady stream of investment has driven tremendous growth in subsea cable infrastructure to keep pace with ever-increasing bandwidth demand. According to new data from TeleGeography’s Transport Networks Research Service, the aggregate cost of new construction over the past nine years has averaged over $2 billion annually. Take a look at the current state of submarine cable investment in 2026.
