India
India sits at the crossroads of East-West submarine routes, with cables radiating toward Europe, Africa, Southeast Asia and beyond. Chennai and Mumbai anchor the country's two primary landing clusters.

A strategic midpoint on global routes
India's position on the Eurasian landmass places it squarely along the principal submarine corridors connecting Europe to Southeast Asia and East Asia. That geography has made it an unavoidable waypoint for some of the longest cable systems in existence, and the country's two documented landing points — Chennai on the Bay of Bengal coast and Mumbai on the Arabian Sea — reflect the logic of those routes rather than any single planning decision.
The cable mix
Eight active systems serve India according to the register. The mix spans several generations of deployment, from the Tata Indicom India-Singapore Cable System (TIISCS), which entered service in 2004, through to Asia-Africa-Europe 1 (AAE-1), commissioned in 2017. I-ME-WE, ready for service in 2010, extends across more than 12,000 km, while SAFE and the Europe India Gateway (EIG) — at roughly 13,100 km and 15,000 km respectively — underline the distances these systems must bridge to connect South Asia with Europe and eastern Africa.
The remaining systems — BBG, Bharat Lanka Cable System and IOCOM — have fuller technical details pending in the register. What is clear from the list as a whole is that India is served by cables pointing in multiple compass directions: westward toward the Middle East and Europe, southward toward Sri Lanka and Africa, and eastward toward Southeast Asia and beyond.
Capacity and resilience signals
The breadth of that directional spread is meaningful. A country whose international connectivity depends on a single corridor faces acute vulnerability whenever that corridor is disrupted by a fault, an anchor drag or a seismic event. India's eight-cable inventory, spanning at least two distinct landing points and several distinct route families, suggests a reasonable degree of path diversity. Chennai and Mumbai effectively divide the country's traffic between two coastlines, so a localised incident affecting one landing cluster does not automatically strand traffic destined for the other.
That said, route diversity on paper does not guarantee capacity redundancy in practice — several of these systems share physical proximity along the seabed through the Red Sea and the Strait of Malacca, meaning a single concentrated fault zone can affect multiple cables simultaneously.
Geography as constraint and advantage
India's peninsular shape, extending into the Indian Ocean between two major sea lanes, is both an advantage and a constraint. It shortens cable runs between Europe and Asia, making Indian landing points commercially attractive. It also means that much of the country's international traffic must transit one of two choke-point zones — the Red Sea to the west or the Andaman Sea to the east — where cable density is high and repair vessel access can be complicated.
