Transatlantic telegraph cable today

News that Russia could be working on plans to sever key internet communications during future wars brings to mind author Tom Clancy and The Hunt for Red October. Indeed, The New York Times first reported in late October that some military sources are worried about a spike in Russian naval activity near the locations of undersea cables.

These cables are vital to the Internet's daily operations and move huge amounts of data between continents. In our world laced with dozens of undersea fiber-optic cables providing Gbps links among continents and remote islands, it is hard to imagine the effort and anguish behind the first transatlantic cable effort. The cables themselves are optical fibers with all-optical amplifiers that are wrapped in multiple layers of specialized polymers and steel jacketing for protection against ocean floor hazards, sharks, ship anchors and fishing nets.

While laying these cables is not routine by any means, it is a carefully planned effort with almost assured success. A recent BBC report says that Russia watchers have long known of the threat to undersea communications and internet cables. However, they say that cutting the U. Such was not the case years ago. The story of the first submarine telegraph cable to span the Atlantic Ocean is a throwback to a different world. It is a tale of financial commitment, abortive attempts and major setbacks, renewed commitment and technical innovation within severe limitations, all leading to an eventual—albeit long-delayed—success.

The year effort yielded the first message to Europe in Julyand shrank the Earth's distances and associated time lags in ways that changed nearly everything about commerce, politics, diplomacy and even war. Many of the technological, material and production advances that the cable-laying venture used remain with us today. Manpower, in the literal sense of the word, was key: although steam engines for power were available, such machines were not suitable for all aspects of the project. As a result, many tasks could only be done by hundreds of laborers working around the clock.

References listed at the end of this article will direct interested readers—and perhaps even an international spymaster or two—to more in-depth studies. However, here are some specific facets of the undertaking that are worth knowing. These include engineering demands and advances in material science, ocean sailing, mass production and at-sea project implementation, all undertaken on a scale that at the time was both inconceivable and yet exciting.

The project was largely financed by self-made businessman Cyrus Field West and a consortium he put together. He had the idea in and expected the effort would take a few years and a few million dollars. In fact, the effort required no fewer than four attempts made over more than a decade, and at a cost of tens of millions of mid th -century dollars.Transatlantic telegraph cables were undersea cables running under the Atlantic Ocean used for telegraph communications.

Telegraphy is now an obsolete form of communication and the cables have long since been decommissioned, but telephone and data are still carried on other transatlantic telecommunications cables. The first communications occurred August 16, but the line speed was poor and efforts to improve it caused this cable to fail after three weeks.

Cyrus West Field and the Atlantic Telegraph Company were behind the construction of the first transatlantic telegraph cable.

The cable functioned for only three weeks, but it was the first such project to yield practical results. The first official telegram to pass between two continents was a letter of congratulations from Queen Victoria of the United Kingdom to President of the United States James Buchanan on August Signal quality declined rapidly, slowing transmission to an almost unusable speed.

The cable was destroyed the following month when Wildman Whitehouse applied excessive voltage to it while trying to achieve faster operation. It has been argued that the faulty manufacture, storage and handling of the cable would have led to premature failure in any case. The second cable was laid in with much-improved material. More than halfway across, the cable broke and after many rescue attempts, they had to give up.

On 13th July the Great Eastern steamed westward to Hearts Content Newfoundland and two weeks later on July 27th the successful connection was put into service. The cable was also retrieved and spliced so two cables were in service. This cable altered for all time personal, commercial and political relations between people across the Atlantic. Since there has been a permanent cable connection between the continents.

In the s duplex and quadruplex transmission and receiving systems were set up that could relay multiple messages over the cable.

Sometimes, however, severe winter storms delayed ships for weeks. The transatlantic cable reduced communication time considerably, allowing a message and a response in the same day. In the s and s several individuals proposed or advocated construction of a telegraph cable across the Atlantic Ocean, including Edward Thornton and Alonzo Jackman. As early as Samuel F. Morse proclaimed his faith in the idea of a submarine line across the Atlantic Ocean.

Mullockhead of the Roman Catholic Church in Newfoundlandproposed a telegraph line through the forest from St.The tech giant says it is incorporating new technology into the cable, which it claims is a significant upgrade to older existing lines.

The cables are usually built by communications firms - typically a group of them pooling resources - which then charge other companies to use them.

The latest cable, named "Grace Hopper" after an American computer scientist and naval rear admiral, will hit the UK at Bude, in Cornwall.

It is Google's fourth privately owned undersea cable. But Google needs "an ever-increasing amount of transatlantic bandwidth", according to John Delaney from telecoms analyst IDC.

Jayne Stowell, who oversees construction of Google's undersea cable projects, told the BBC it needed an internet connection that could be relied upon. The first ever transatlantic telecommunications cable was built inconnecting Ireland and the US by telegraph.

Aroundmiles of cable already run between continents to support the demand for communication and entertainment - enough to run around the world almost 17 times. Cables are required to withstand major hazards, including earthquakes and heavy currents, and have a lifespan of around 25 years.

But Ms Stowell says some of the transatlantic cables are "going out of service and we need newer, better and more sophisticated technology". Google has yet to build a cable that lands in mainland China, where its services are restricted by the state and Ms Stowell said there are no plans to build one in the foreseeable future.

But she pointed out that the Asia market was bigger than China. She also addressed growing fears that the world could soon see two internets: one controlled by the West and the other by China.

One would hope networks would be regarded as neutral and continue to interconnect. Internet usage has skyrocketed around the world since Covid restrictions were introduced.

Africa lags behind the rest of the world in terms of internet access, with only four in 10 people having access to the web. However, with a population of 1. Google and Facebook too powerful, says watchdog.The effects of the poor handling and design of that cable, coupled with repeated attempts to drive the cable with high voltages, led to its failure in September Transatlantic telegraph cables have since been replaced by transatlantic telecommunications cables.

Before the first transatlantic cable, communications between Europe and the Americas took place only by ship. Sometimes, however, severe winter storms delayed ships for weeks. William Cooke and Charles Wheatstone introduced their working telegraph in As early asSamuel F.

Morse proclaimed his faith in the idea of a submarine line across the Atlantic Ocean.

Bya cable was run between England and France. That same year Bishop John T. Mullock, head of the Roman Catholic Church in Newfoundland, proposed a telegraph line through the forest from St.

At about the same time a similar plan occurred to Frederick Newton Gisborne, a telegraph engineer in Nova Scotia. In the spring ofGisborne procured a grant from the legislature of Newfoundland and, having formed a company, began the construction of the landline. In his company collapsed, he was arrested for debt and he lost everything. The following year he was introduced to Cyrus West Field.

Field invited Gisborne to his house to discuss the project. From his visitor, Field considered the idea that the cable to Newfoundland might be extended across the Atlantic Ocean.

Field was ignorant of submarine cables and the deep sea. He consulted Morse as well as Lieutenant Matthew Maury, an authority on oceanography. The first step was to finish the line between St.

It was laid out from a barque in tow of a steamer. When half the cable was laid, a gale rose, and the line was cut to keep the barque from sinking. Ina steamboat was fitted out for the purpose, and the link from Cape Ray, Newfoundland to Aspy Bay, Nova Scotia was successfully laid.

With Charles Tilston Bright as chief engineer, Field then directed the transoceanic cable effort. A survey was made of the proposed route and showed that the cable was feasible. Funds were raised from both American and British sources by selling shares in the Atlantic Telegraph Company.

Field himself supplied a quarter of the needed capital. Late in manufacturing it was discovered that the respective sections had been made with strands twisted in opposite directions. While the two sections proved a simple matter to join, this mistake subsequently became magnified in the public mind. Field also solicited aid from the U. A bill authorizing a subsidy was submitted in Congress. The subsidy bill passed the Senate by a single vote, due to opposition from protectionist senators.

In the House of Representatives, the bill encountered similar resistance, but passed, and was signed by President Franklin Pierce. The first attempt, inwas a failure. The cable was started at the white strand near Ballycarbery Castle in County Kerry, on the southwest coast of Ireland, on August 5, The following summer, after experiments in the Bay of Biscay, Agamemnon and Niagara tried again.After several unsuccessful attempts, the first telegraph line across the Atlantic Ocean is completed, a feat accomplished largely through the efforts of American merchant Cyrus West Field.

The telegraph was first developed by Samuel F. Morse, an artist-turned-inventor who conceived of the idea of the electric telegraph in Several European inventors had proposed such a device, but Morse worked independently and by the mid s had built a working telegraph instrument. In the late s, he perfected Morse Code, a set of signals that could represent language in telegraph messages.

Within a decade, more than 20, miles of telegraph cable crisscrossed the country. The rapid communication it made possible greatly aided American expansion, making railroad travel safer as it provided a boost to business conducted across the great distances of a growing United States. InCyrus West Field conceived the idea of the telegraph cable and secured a charter to lay a well-insulated line across the floor of the Atlantic Ocean. Obtaining the aid of British and American naval ships, he made four unsuccessful attempts, beginning in In Julyfour British and American vessels—the Agamemnon, the Valorous, the Niagara, and the Gorgon —met in mid-ocean for the fifth attempt.

By August 5, the cable had been successfully laid, stretching nearly 2, miles across the Atlantic at a depth often of more than two miles. Unfortunately, the cable proved weak and the current insufficient and by the beginning of September had ceased functioning. Field later raised new funds and made new arrangements.

He later promoted other oceanic cables, including telegraph lines that stretched from Hawaii to Asia and Australia. But if you see something that doesn't look right, click here to contact us! On August 5,the rusty iron gun turret of the U. Monitor broke from the water and into the daylight for the first time in years. The ironclad warship was raised from the floor of the Atlantic, where it had rested since it went down in a storm off Cape Hatteras,A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other.

In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the century, all used optical fiberand most now use optical amplifiers. When the first transatlantic telegraph cable was laid in by Cyrus West Fieldit operated for only three weeks; subsequent attempts in and were more successful. TAT-1 Transatlantic No. It was laid between Gallanach Bay, near Obanand ClarenvilleNewfoundland between and by the cable ship Monarch.

In the first 24 hours of public service, there were London—U. The capacity of the cable was soon increased to 48 channels. Later, an additional three channels were added by use of C Carrier equipment. Time-assignment speech interpolation TASI was implemented on the TAT-1 cable in June and effectively increased the cable's capacity from 37 out of 51 available channels to 72 speech circuits.

TAT-1 was finally retired in Later coaxial cables, installed through the s, used transistors and had higher bandwidth. The Moscow—Washington hotline was initially connected through this system. All cables presently in service use fiber optic technology. There has been a succession of newer transatlantic cable systems. All recent systems have used fiber optic transmission, and a self-healing ring topology. Late in the 20th century, communications satellites lost most of their North Atlantic telephone traffic to these low-cost, high-capacity, low- latency cables.

This advantage only increases over time, as tighter cables provide higher bandwidth — the generation of cables drop the transatlantic latency to under 60 milliseconds, according to Hibernia Atlanticdeploying such a cable that year.

All TAT cables are joint ventures between a number of telecommunications companies, e. British Telecom. From Wikipedia, the free encyclopedia. Communications cable across the Atlantic.
