132 submarine cables entered service since 2020 — from a 15 km island hop to 2Africa's 45,000 km loop

Asked:

“Map every submarine internet cable that entered service since 2020: name, landing points, length, owners, and capacity.”

This public-web inventory covers all 132 distinct cable systems with a stated ready-for-service or activation year from 2020 through 23 September 2026: 19 in 2020, 20 in 2021, 19 in 2022, 21 in 2023, 16 in 2024, 12 in 2025 and a provisional 25 in 2026. Lengths are in km; capacities are published design capacities in Tbps, not lit capacity — blanks mean no verified public figure.

Routes on the map are schematic great-circle lines inferred from public landing-place names, not surveyed seabed paths. 104 of 132 cables have two or more confidently located landings and are drawn; the other 28 appear only in the table — no coordinates were invented. 2026 entries reflect expected or current-RFS language and are provisional.

2Africa (2024) is the longest system at 45,000 km, ringing the African continent with dozens of landings from Europe to Asia — a Meta-backed consortium build. geocables.com

27 of the 132 systems name Google, Meta, Microsoft or Amazon among their owners — hyperscalers now back roughly one in five new cables, including Curie, Dunant, Equiano, Firmina and Nuvem. dgtlinfra.com

The spread is extreme: Coral Bridge spans just 15 km while five systems exceed 18,000 km; the seven cohorts together state about 638,000 km of new cable. submarinenetworks.com

The 2026 cohort of 25 systems is the largest of any year and states roughly 163,600 km — but many sources use expected-RFS language, so treat it as provisional. riotimesonline.com

Cables per RFS year

Bar labels show cable count; 2026 is provisional.

Length vs design capacity

69 of 132 cables publish a design capacity (Tbps, log scale). Design capacity is not lit capacity.

Method: best-effort public-web inventory of submarine cable systems with a stated ready-for-service or activation year 2020–2026, compiled as of 2026-09-23 from roughly 1,150 search-result pages (Submarine Networks, GeoCables, SubTel Forum, operator and news pages, and others); 132 rows across multiple independent hosts, the largest host supplying 32 of 132 and no single URL more than half. Length in km and design capacity in Tbps as published; blanks mean no verified figure. Map routes are schematic great circles between named landing places, not seabed paths; 28 cables lack locatable landings and are table-only. RFS years may conflate whole-system and phased-branch activation; 2026 is provisional. Not an official exhaustive register.
