In <strong>1851<\/strong>, the <strong>first submarine cable<\/strong> was laid between <strong>Dover and Cap Gris-Nez<\/strong>. This installation was essential and a <strong>great success<\/strong> for economic development. By laying the telegraph cable, a telephone <strong>connection between France and England<\/strong> was now established.   <\/p>\n\n<p>Through this innovation, a new goal was eventually achieved: <strong>Transatlantic submarine cables<\/strong> connecting Europe with America. In 1988, the first transatlantic fiber optic cable named <strong>TAT8<\/strong> was laid between the USA, France, and Great Britain. Through the steady growth of the infrastructure, improved construction methods developed.  <\/p>\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"710\" height=\"399\" src=\"https:\/\/leitzcloud.eu\/wp-content\/uploads\/2020\/01\/verlegung_unterseekabel.jpeg\" alt=\"\" class=\"wp-image-6263\" srcset=\"https:\/\/leitzcloud.eu\/wp-content\/uploads\/2020\/01\/verlegung_unterseekabel.jpeg 710w, https:\/\/leitzcloud.eu\/wp-content\/uploads\/2020\/01\/verlegung_unterseekabel-300x169.jpeg 300w\" sizes=\"(max-width: 710px) 100vw, 710px\" \/><\/figure>\n\n<div style=\"height:38px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h3 class=\"wp-block-heading\">Installation of Deep-Sea Cables<\/h3>\n\n<p>Using specialized vessels, the submarine cables are <strong>buried in the seabed<\/strong>.

In the second variant, the seabed is <strong>opened<\/strong> using a <strong>submarine cable plow<\/strong> and the cable is laid in.

Currently, the <strong>USA<\/strong> and the <strong>People&#8217;s Republic of China<\/strong> are engaged in a competition in the construction of submarine cables. For alongside China&#8217;s largest <strong>foreign policy project<\/strong>, the construction of the <strong>new Silk Road<\/strong>, China also wants to participate in the <strong>expansion<\/strong> of submarine cables.  <\/p>\n\n<p>In <strong>Marseille<\/strong>, the People&#8217;s Republic of China is building the submarine cable <strong>&#8220;Peace&#8221;<\/strong>. The <strong>12,000 km<\/strong> long cable is intended to connect China with Europe via the Horn of Africa and Pakistan. <\/p>\n\n<p><strong>Critics<\/strong> fear that <strong>China<\/strong> is building and financing the deep-sea cable in order to <strong>intercept<\/strong> the <strong>data<\/strong> of European citizens. This would <strong>not<\/strong> be a new phenomenon. In <strong>2013<\/strong>, former CIA agent <strong>Edward Snowden<\/strong> revealed that the <strong>USA<\/strong> had been intercepting data from <strong>governments<\/strong> as well as from <strong>millions<\/strong> of people for years by <strong>tapping deep-sea cables<\/strong>. <\/p>\n\n<p>Some time ago, <a href=\"https:\/\/internationalepolitik.de\/de\/unterseekabel-kritisch-ungeschuetzt\">Robert Martinage<\/a>, a former Deputy Undersecretary of the US Navy and Pentagon official, criticized the fact that while many states prioritize cybersecurity, the physical infrastructure of the internet is less protected.<\/p>\n\n<div class=\"wp-block-media-text has-media-on-the-right is-stacked-on-mobile\"><div class=\"wp-block-media-text__content\">\n<p>In addition to security risks, submarine cables can also be damaged by <strong>natural forces<\/strong> or fall victim to <strong>boat anchors<\/strong> and <strong>trawl nets<\/strong>.
