Comfortable holidays, TeleGeography Explains the Web listeners.
What have been the large cable headlines of this yr, and what do that you must find out about transport networks in 2026?
To search out out, we’re kickstarting our three-episode evaluate of What to Know within the New Yr. To begin, we’ve got a submarine and terrestrial infrastructure evaluate alongside buddies of the pod Lane Burdette and Paul Brodsky.
Hearken to the complete episode beneath.

Key Takeaways
The Submarine Cable Funding Increase Will Maintain 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 practically 40 cables come on-line.
This potential surge represents a capital expenditure of roughly $6 billion, which is the best quantity seen in a minimum of a decade. Regardless of this large inflow of capability, analysts don’t foresee a worth collapse as a result of a lot of this infrastructure is being constructed immediately by content material suppliers, resembling Google, for their very own inner use somewhat than for aggressive sale.
Geopolitical Conflicts are Forcing New Route Diversification
The Purple Sea has grow to be a crucial bottleneck as a consequence 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 standard transit by Egypt, the business is more and more growing terrestrial fiber networks by 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 Indonesia and the Philippines as a substitute.
Energy Availability for AI is Dictating Community Geography
The rise of AI is reversing conventional community planning; somewhat than knowledge facilities being constructed the place networks exist, community connectivity is now “chasing” knowledge facilities to areas the place electrical energy is on the market.
This has led to infrastructure growth in novel areas 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, firms are prioritizing the buildup of darkish fiber and numerous routes now to make sure they don’t seem to be caught brief later.
Terrestrial and Subsea Networks Face Drastically Completely different Bodily Limits
There is a large disparity in capability potential between terrestrial and submarine networks as a result of availability {of electrical} energy for sign amplification.
Whereas terrestrial conduits can help hundreds of fiber pairs as a result of energy is definitely accessible, submarine cables are at the moment restricted to roughly 24 fiber pairs due to the problem in sending electrical energy throughout oceans to energy amplifiers.
Consequently, whereas subsea capability is a scarce asset, terrestrial builders can push large quantities of bandwidth and give attention to creating resilient mesh networks with 4 or 5 numerous routes into key nodes.
