Comfortable holidays, TeleGeography Explains the Web listeners.
What had been the massive cable headlines of this yr, and what do it’s worthwhile to find out about transport networks in 2026?
To seek out out, we’re kickstarting our three-episode assessment of What to Know within the New Yr. To start out, we’ve a submarine and terrestrial infrastructure assessment alongside mates of the pod Lane Burdette and Paul Brodsky.
Hearken to the total episode under.

Key Takeaways
The Submarine Cable Funding Growth Will Hold Boomin’ in 2026
Whereas 2025 was already a powerful yr with roughly 15 new submarine cables coming into service—representing about $3.2 billion in worth—2026 is projected to see almost 40 cables come on-line.
This potential surge represents a capital expenditure of roughly $6 billion, which is the very best quantity seen in no less than a decade. Regardless of this huge inflow of capability, analysts don’t foresee a value collapse as a result of a lot of this infrastructure is being constructed immediately by content material suppliers, akin to Google, for their very own inner use relatively than for aggressive sale.
Geopolitical Conflicts are Forcing New Route Diversification
The Purple Sea has change into a important bottleneck as a result of battle in Yemen, which has made it extraordinarily troublesome for restore ships to safe permits to repair broken cables, leaving some techniques stranded indefinitely. To mitigate reliance on this route and the normal transit by way of Egypt, the trade is more and more creating terrestrial fiber networks by way of Saudi Arabia, the UAE, Jordan, and Israel.
Moreover, new submarine routes are being designed to skirt different delicate areas, such because the South China Sea, using paths by way of Indonesia and the Philippines as a substitute.
Energy Availability for AI is Dictating Community Geography
The rise of AI is reversing conventional community planning; relatively than knowledge facilities being constructed the place networks exist, community connectivity is now “chasing” knowledge facilities to places the place electrical energy is accessible.
This has led to infrastructure improvement in novel places starting from West Texas and Iowa to Christmas Island, the latter serving as a brand new hub for Google’s techniques. As a result of the long run bandwidth calls for of AI are nonetheless unknown, corporations are prioritizing the buildup of darkish fiber and various routes now to make sure they don’t seem to be caught quick later.
Terrestrial and Subsea Networks Face Drastically Totally different Bodily Limits
There is a huge disparity in capability potential between terrestrial and submarine networks as a result of availability {of electrical} energy for sign amplification.
Whereas terrestrial conduits can assist hundreds of fiber pairs as a result of energy is well accessible, submarine cables are at the moment restricted to roughly 24 fiber pairs due to the issue in sending electrical energy throughout oceans to energy amplifiers.
Consequently, whereas subsea capability is a scarce asset, terrestrial builders can push huge quantities of bandwidth and give attention to creating resilient mesh networks with 4 or 5 various routes into key nodes.
