Pleased holidays, TeleGeography Explains the Web listeners.
What have been the massive cable headlines of this 12 months, and what do you have to learn about transport networks in 2026?
To search out out, we’re kickstarting our three-episode evaluation of What to Know within the New 12 months. To start out, now we have a submarine and terrestrial infrastructure evaluation alongside mates of the pod Lane Burdette and Paul Brodsky.
Take heed to the total episode under.

Key Takeaways
The Submarine Cable Funding Growth Will Preserve Boomin’ in 2026
Whereas 2025 was already a robust 12 months with roughly 15 new submarine cables getting 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 best quantity seen in at the very least 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 straight by content material suppliers, reminiscent of Google, for their very own inside use reasonably than for aggressive sale.
Geopolitical Conflicts are Forcing New Route Diversification
The Crimson Sea has change into a vital bottleneck resulting from battle in Yemen, which has made it extraordinarily troublesome for restore ships to safe permits to repair broken cables, leaving some methods stranded indefinitely. To mitigate reliance on this route and the normal 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; reasonably than knowledge facilities being constructed the place networks exist, community connectivity is now “chasing” knowledge facilities to places the place electrical energy is obtainable.
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 methods. As a result of the longer term bandwidth calls for of AI are nonetheless unknown, corporations 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 Totally 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 assist hundreds of fiber pairs as a result of energy is well accessible, submarine cables are at present 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 large quantities of bandwidth and concentrate on creating resilient mesh networks with 4 or 5 numerous routes into key nodes.
