No new cable is being laid; instead, new terminal equipment will let existing fibre carry more capacity to meet rising demand from cloud and AI companies. The Monet cable will gain 800Gbit/s client connections, while both cables get more flexible capacity options ranging from 100Gbit/s links to full fibre pairs. Neither company disclosed contract value or completion timeline. The upgrade builds on a partnership dating to 2017, when Ciena was first selected as Monet's technology supplier, and a 2021 capacity boost. ## Full article daily.dev links to this article rather than hosting it.

Angola Cables is installing Ciena Waveserver hardware running WaveLogic 6 Extreme optical technology on the Monet cable, enabling 800Gbit/s client connections. No new cable is being laid; the upgrade uses new terminal equipment on the existing fibre. Customers will be able to buy links ranging from a single 100Gbit/s connection up to an entire fibre pair. The contract value and completion date were not disclosed. _daily.dev surfaces infrastructure upgrades like this for engineers tracking global network capacity changes._ ### How does the Sacs subsea cable route between Africa and Brazil compare to going via Europe? The South Atlantic Cable System (Sacs) runs 6,165km from Sangano, Angola to Fortaleza, Brazil, and was projected to cut latency between Cape Town and Miami from 338ms to 163ms compared to routing via Europe. Combined with the Monet cable, which links Brazil to Boca Raton, Florida, total Africa-to-US round trip latency is about 130ms. _Engineers evaluating routing and latency trade-offs can follow subsea cable developments on daily.dev._ ### What happened when subsea cables broke off Côte d'Ivoire in March 2024? Breaks off Côte d'Ivoire in March 2024, blamed on a suspected subsea seismic event, knocked out the West Africa Cable System (Wacs) and other west coast cables, disrupting internet services across South Africa. Much of the affected traffic was quickly rerouted along alternative cables, including Google's Equiano system and the Sacs cable linking Angola to Brazil. _daily.dev helps infrastructure teams stay on top of connectivity incidents affecting internet routing resilience._ ## Similar posts on daily.dev - [Google’s newest data pipeline runs beneath the Atlantic to Portugal](https://daily.dev/posts/google-s-newest-data-pipeline-runs-beneath-the-atlantic-to-portugal-cyjhy8ez7) · The Next Web · 0 upvotes · 0 comments - [Ageing Safe cable prompts new R1.7-billion Indian Ocean link](https://daily.dev/posts/ageing-safe-cable-prompts-new-r1-7-billion-indian-ocean-link-0yvbfykc8) · TechCentral · 1 upvotes · 0 comments - [The lone ship guarding Africa’s internet](https://daily.dev/posts/the-lone-ship-guarding-africa-s-internet-6h9vrddk3) · TechCentral · 0 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking) [View this post on daily.dev](https://daily.dev/posts/africa-s-internet-bridge-to-the-us-gets-an-upgrade-1cnz40nvp) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Africa’s internet bridge to the US gets an upgrade","url":"https://daily.dev/posts/africa-s-internet-bridge-to-the-us-gets-an-upgrade-1cnz40nvp","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/africa-s-internet-bridge-to-the-us-gets-an-upgrade-1cnz40nvp"},"datePublished":"2026-09-30T09:19:01.728Z","dateModified":"2026-09-30T09:19:26.470Z","description":"Angola Cables is upgrading its Monet and Sacs subsea cable systems linking Africa, Brazil and the US using Ciena equipment, including Waveserver hardware with...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/250b5023c370cb6fbe235d82784bb9b1?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/250b5023c370cb6fbe235d82784bb9b1?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCentral","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCentral","logo":"https://media.daily.dev/image/upload/s--RsqLDZrL--/f_auto/v1717745297/logos/techcentral","url":"https://daily.dev/sources/techcentral"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/africa-s-internet-bridge-to-the-us-gets-an-upgrade-1cnz40nvp","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"networking","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCentral","item":"https://daily.dev/sources/techcentral"},{"@type":"ListItem","position":3,"name":"Africa’s internet bridge to the US gets an upgrade"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/africa-s-internet-bridge-to-the-us-gets-an-upgrade-1cnz40nvp#faq","mainEntity":[{"@type":"Question","name":"What upgrade is being made to the Monet subsea cable connecting the US and Brazil?","acceptedAnswer":{"@type":"Answer","text":"Angola Cables is installing Ciena Waveserver hardware running WaveLogic 6 Extreme optical technology on the Monet cable, enabling 800Gbit/s client connections.
