Resiliency is critical

As of June 2023, that’s a whopping 485 in-service systems, with another 70 planned.The number of cable systems we study is constantly increasing. This is due to massive investment in this infrastructure—both along major routes and to small islands.

++ MainOne Network Outage: Submarine Cable Fault Disrupts Services in West Africa ++On Thursday, March 14, 2024, MainOne experienced a significant network fault, disrupting services for customers. The fault, occurring on the MainOne network, resulted from environmental factors like landslides and earthquakes, leading to a cut on the submarine cable system in the Atlantic Ocean off the coast of West Africa.Repair efforts are underway, managed by Atlantic Cable Maintenance and Repair Agreement (ACMA). However, the repair process, involving identifying the fault, retrieving spares, sailing to the fault location, and conducting repairs, is estimated to take 1-2 weeks, with additional transit time for vessel mobilization.#techafricanews #africa #westafrica #network #outage #submarine #cable #maintainance #repair #network

As we anticipate the European Commission to expand on the strategic importance of properly funding and governing #submarinecable systems in the coming weeks, ETNO Association has released a reflection paper with our initial perspectives on augmenting the #resilience and #security of the Union’s subsea cable infrastructure. Looking forward to contributing more to this crucial debate.

Subsea Cables RFS 2025: Eastern LightEastern Light aims to build the first new subsea cable connecting Stockholm to Helsinki in the last ten years. The strategy here is quite different from the standard subsea cable providing Layer 1 lit services such as wavelengths. Instead, Eastern Light plans to offer short and medium term fibre pair leases as well as standard IRUs. Because the cable will be a straight optical shot with no repeaters, it really qualifies as a long haul subsea dark fibre play. Each customer will presumably select their own submarine line termination equipment as well as DWDM kit.The overall design has a lot to recommend it. Horizontal directional drilling is used to install a bore pipe through which the submarine cable is threaded all the way to the beach manhole. At the beach manhole the fibre will spliced to the terrestrial back haul network. Bore pipes provide the best protection for a subsea cable. The system will also avoid the use of connectors as much as possible because optical loss is greater than traditional fibre fusing. I have not been able to find the number of pairs, but a good guess is from 48 to 96.I have two concerns with the project, which I do hope does materialize. First of all, it is not clear there is sufficient demand to sell most of the pairs. It would require extraordinary data center growth to drive that demand and a Finnish data center due to latency constraints can only really serve Finland, Sweden, and the Baltics. Northeastern Russia is a potential target, but Russia's Internet has become detached from the global Internet. The second issue is that no financing has been announced. Typically if you have financing, you announce it. It creates credibility, a currency just as valuable as the USD or Euro. How do we tell if it is going to happen or not? Look for photos of cable ships or cable landings.#easternlight #finland #sweden #subseacables #unrepeatered #darkfibre

According to Hamilton Research there are operational, under construction, planned and proposed for a total of 317 network operators and 65 submarine cable systems. HOW IS THIS FIBER DISTRIBUTED? Maps help but we need a database breaking down the terrestrial fiber assets per country and operator. Africa’s total inventory of terrestrial transmission networks:1,474,983-km in 20191,,389,475-km in 2018, 1,254,413-km in 2017, 1,179,010-km in 2016, 1,019,649-km in 2015, 958,901-km in 2014. Ten years ago in June 2009, the total inventory of terrestrial transmission networks was 465,659-km.

Shoring up LatAm’s submarine cable industry – the tasks that lie aheadDriven by the increase in global traffic and content exchanges, the submarine cable segment in Latin America continues to thrive, with various projects under development and capacity upgrades underway for older systems.However, there are still some important bottlenecks holding back faster progress.These include the need for a greater diversity of routes and landing points, industrial policies to develop local suppliers and launchers, and coastal cable protection programs, key industry players highlighted at an industry event last week.Rogério Mariano, head of Edge Network Planning at Azion, is among those advocating for the creation of submarine cable protection programs in the various countries in the region, along the lines of what is already happening in Europe and other markets.Azion is one of the leading edge computing and interconnectivity companies in the Americas, and Mariano is a longstanding expert on submarine cables.“Protection and resilience of cables is essential. We've been working on this for a year and a half. Last year we had three incidents considered important: the cutting of the SACS cable by a vessel in September, the cutting of the WACS [cable off the coast of Africa, owned by Angola Cables], and the third was the desalination plant [conflict] in Fortaleza, which is now pacified, but it took a long time,” the executive said at the event.https://lnkd.in/gmzMMCRR
