Blissful holidays, TeleGeography Explains the Web listeners.
What had been the large cable headlines of this 12 months, and what do it’s essential to learn about transport networks in 2026?
To seek out out, we’re kickstarting our three-episode evaluation of What to Know within the New 12 months.Ā To begin, we’ve a submarine and terrestrial infrastructure evaluation alongsideĀ buddies of the pod Lane Burdette and Paul Brodsky.

Key Takeaways
The Submarine Cable Funding Increase Will Preserve Boomin’ in 2026
Whereas 2025 was already a powerful 12 months with roughly 15 new submarine cables coming into serviceārepresenting about $3.2 billion in worthā2026 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 at the least a decade. Regardless of this huge 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, comparable to Google, for their very own inside use moderately than for aggressive sale.
Geopolitical Conflicts are Forcing New Route Diversification
The Pink Sea has turn into a essential bottleneck resulting from battle in Yemen, which has made it extraordinarily tough for restore ships to safe permits to repair broken cables, leaving some methods stranded indefinitely. To mitigate reliance on this route and the standard transit by Egypt, the business is more and more creating 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 an alternative.
Energy Availability for AI is Dictating Community Geography
The rise of AI is reversing conventional community planning; moderately 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, firms 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 definitely accessible, submarine cables are presently restricted toĀ 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 concentrate on creating resilient mesh networks with 4 or 5 various routes into key nodes.
