By Suvesh Chattopadhyaya This question has intrigued me for the last 6 months - does India have sufficient number of subsea or submarine cables landing on its western and southern shores that provide the underlying foundation of global connectivity infrastructure to boost the resurgent economy. Does it have the critical mass to be the catalyst and enabler for next-gen business ecosystem that are heavily dependent on connectivity superhighways. Undeniably the mesh of trans-oceanic fiber optic cables crisscrossing the globe are the bedrock for accelerated proliferation of globalization and digital transformation for everything it means and stands for, both inside-out and outside-in. This article takes a closer look at the subsea cable infrastructure in India, its uniqueness, the competitive providers and the roadmap.
By Suvesh Chattopadhyaya Telegeography reported there are 366 subsea cables with 1006 cable landing stations globally and this includes subsea cables that are currently active, under construction, or expected to be fully-funded by the end of 2020. A market survey indicates nearly 30 cables are under construction and new announcements would be in addition to it. Undeniably, that’s quite impressive market landscape of subsea cables.
The majority of people around the world, including George Clooney in “Gravity” believe that the Internet’s connectivity is provided by satellite communications. Not so, I hear the likes of the content providers such as Amazon, Facebook, Google, Microsoft, as well as all the telecommunications companies say. For the moment, they are correct in that about 99.5% of our international data and voice connectivity is provided over submarine fibre cables which cross-cross the world. The global submarine network is comprised of an estimated 213 independent fibre cable systems totalling c 550,000 miles (900,000 km) of fibre. Each year sees another 20-30 submarine cables systems being built to augment or replace the existing cables, provide additional diversity and connectivity enabling more capacity for the global Internet.
By Yiannis Giokas Recently China’s President Xi announced that the first overseas military bases for his country started operating in Djibouti, by the Horn of Africa. Djibouti?
Djibouti is a small country in East Africa with less than one million inhabitants but is situated in a highly strategic part of the world, it is next to Mandeb Strait and to the entrance of Suez-Aden canal, hence close to most of the East — West commerce, including oil. However, in today’s internet economy this could be considered a side business; since the most important thing about Djibouti is that it is a node that gathers the majority of submarine cable systems that connect East and West, making this tiny country a critical part of the infrastructure on which we depend our internet.
By Peter Zwinkels The subsea cable market is booming with approximately $9.8 billion in new cables expected to enter service between 2016 and 2018 driven largely by the cloud. The deployment of a subsea cable of over 10,000 kilometers (km) in length can cost more than $500 million, with multiple investors typically financing the venture. Further, a subsea cable has relatively few fibers compared to a terrestrial network because each fiber requires its own repeaters spaced about every 80 km. Given that a single subsea cable usually houses only up to eight fiber pairs, you can probably guess what an investor is thinking: how can I maximize my return on investment with only a few fibers? The answer is simply to get as much revenue as possible out of the cable during its roughly 25-year lifespan. This means maximizing the capacity on the cable is critical. Thus, subsea cable operators are eager to deploy the fastest technology available for maximum capacity-reach performance, or more saliently, revenue-reach performance. In this blog let us look at the latest technology subsea cable operators can use to get the most potential from their cable.
With the growth of new submarine cables and the exponential increase in required bandwidth, consortium and private cable owners must be looking at their older cables with some concern. When these submarine cables were originally built in the mid 1990's, the expected system life was 15-20 years before they would need to be replaced.
Due to technology improvements and the financial downturn post 2000 these cables have had mid-life capacity upgrades, although they now approaching their original planned end of life. However the Operational and Maintenance cost for these cables is higher than on newer systems, primarily due to increased capacity and better wet plant technology; and the break-even point is approaching when these systems are likely to be retired, as they are simply too expensive to keep running.
By Abdul Ravoof Submarine networks carry over 99% of the world’s Intercontinental electronic communications traffic. There is misconception that Satellites carry data from continent to continent. If we ask anyone in the world, 95% of people give answer as satellites carry international traffic. This is absolutely wrong.
The Internet, International communication, Internet of Things ( IoT), 5G & Cloud Networking. Without submarine cable systems, we cannot imagine all these above
