Facebook’s fiber has landed in South Africa and it’s the world’s longest undersea cable at 45000km

Edwin Chabuka Avatar

Meta’s Facebook is joining the telecoms space and they have decided to come out of the gates with the longest undersea fiber optic cable at 45000km. To make this all happen they formed the 2Africa group which comprises other telecom operators. China Mobile International, Djibouti Telecom, Meta (Facebook), MTN GlobalConnect, Orange, Saudi Telecom Company (STC), Telecom Egypt, Vodafone, and WIOCC is the full list of the consortium.

The progress so far

The plan is for this fiber to cover the east and west sides of Africa. 46 landing points have been established in a total of 33 countries with South Africa being the latest one. There is also a 2Africa Pearls branch connecting to the Middle East and India.

2Africa subsea cable system will support the western and eastern sides of Africa, once complete in 2023 and 2024 respectively,


This fiber cable will be adding an additional 180Tbps of capacity to Africa’s internet. To get an idea of it, Zimbabwe’s average internet bandwidth for Q2 2022 was just under 100Gbps. That is 1800 times what satisfies Zimbabwe so it is a lot of capacity. Of course, all this bandwidth is not going to South Africa but rather it is the capacity of the main 2Africa cable.

Once it goes live, 2Africa will have the highest bandwidth capacity as well as being the only Pan-African subsea cable covering the east and west sides of Africa.

What’s the big deal with this cable?

Additional capacity

2Africa is just an additional link between Africa and the rest of the world when it comes to connectivity. That’s more capacity to connect with the world. Think of it as this. We already have 1 pipe irrigating a field at a certain rate in a field. That’s the internet capacity we already have right now. 2Africa is a second pipe coming in to irrigate the same field meaning the time we take irrigating is reduced.

In internet terms, Africa will have bigger pipes to connect to the world. Bigger pipes translate to faster internet as the obvious benefit, which makes sense considering Africa’s population has grown by over half a billion. In the same period, the internet penetration rate for Africa has gone from 1% to 30% and it’s a pretty exponential-looking graph.

So existing infrastructure was starting to struggle a bit with the rise in demand for internet services. And since bandwidth is a limited resource, all it meant is to manage traffic, speeds may need to be reduced.


Having more options means that there is competitive pricing of internet bandwidth. For coastal countries and especially those with landing sites for these undersea cables, bandwidth is quite affordable. This is primarily because IAPs in these countries have a direct link with the supplier which in this case is 2Africa.

2Africa is at the moment one of over 25 under sea cable providers servicing Africa and them coming into play means IAPs can negotiate for cheaper bandwidth which will also translate to the end user getting cheaper internet.


This now goes to how networks work. A few years ago, a major fiber link owned by Liquid was damaged by a farmer in South Africa causing massive internet blackouts in parts of Zimbabwe. How did this not affect every Liquid Home subscriber? This is because IAPs do not rely on one internet provider. They often have backups such that if one fails they can switch over to another and use that whilst they solve the issue with the other.

2Africa is coming in as an additional bandwidth wholeseller and one that is convenient to us on the southern side of Africa. And more of these players can be strategically chosen by IAPs to improve on availability of the service that they sell to you and me. So if a fault occurs on one link, traffic can be redistributed to other links and the service stays up.

    I honestly don’t know what an IAP is. Can you enlighten me?

    1. Guunyi

      Internet Access Provider (IAP means the telecommunications operator that provides interconnection, and gateway capacity for Internet services.

  2. The Last Don

    Obviously our service providers will still overprice and throttle the speeds like they are used to doing. At the moment they give us 2G speeds disguised as LTE.

    1. Imi Vanhu Musadaro

      I think POTRAZ needs to legally set the minimum speed for all services. Some of these hide behind saying “up to X Mbps”, and thus can’t be sued for constantly providing you lesser speeds.

    Very good news indeed! Can the author look upwards this time and update us on Starlink connectivity to Africa so far.

    1. Anonymous

      Starlink is having trouble doing business outside EU and the US for security reasons..the government can’t control Starlink ones those satellite dishes hit your country…potraz can kiss goodbye to their profits.

      1. D.K.

        Zambia and Malawi have signed some agreements with Starlink. To show that they both do not have anything to hide, governments should trust their citizens, and citizens should trust their governments for real progress to happen.

        1. Anonymous

          The reason why some countries don’t want starlink evading their space is also the same reason why EU and US didn’t want Huawei evading their space…maybe internet is not that dangerous to Zambia and Malawi considering how many of their citizens know how to use it.

    But why are the prices of airtime going up continuosly???

    1. Justforlaughs

      Because your penis is small

    What do Techzim and the fridge have in common? Even though you know there’s nothing there, you still go and check every ten minutes😹

    1. waste

      hahaha true, what a waste of time and data……

      1. Choosing Beggars

        Lets face it, the reason you/we open that ‘fridge door’ so often and have so much time to criticise is precisely because TechZim and Pindula are mostly free and available when the zesa power cuts have you in their tight, dark embrace and the wifi is dead!

  6. Unfocused Youth

    Very interesting read.

  7. Lancet 3 suicide drone

    Facebook is compromised, currently it has at least 115 people in senior positions who previously worked for the FBI, CIA, NSA, or Department of Homeland Security.

    For example, Aaron Berman leads the Disinformation Politics team at Facebook. According to his LinkedIn profile, he worked for the CIA for 17 years.
    They’re just here to increase their hegemony.

    Why does Econet reduce my US$ airtime balance each time I do a balance inquiry?.
