How do they route cables under the sea?

How do they route cables under the sea?

Submarine cables are laid down by using specially-modified ships that carry the submarine cable on board and slowly lay it out on the seabed as per the plans given by the cable operator. The ships can carry with them up to 2,000km-length of cable. Newer ships and ploughs now do about 200km of cable laying per day.

Do cables run under the ocean?

In fact, “Ninety-nine percent of international data is transmitted by wires at the bottom of the ocean called submarine communications cables”, according to Mental Floss. So the vast majority of the information in the world travels through the ocean on over a million kilometers of cable.

How often do undersea cables break?

According to Beckert, cable cuts happen “on average once every three days.” He further noted that there are 25 large ships that do nothing but fix cable cuts and bends, and that such cuts are usually the result of cables rubbing against rocks on the sea floor.

How old is CAT5e?

Cat5e was introduced around 2000 and, as its name suggests, served as an “enhanced” version of Cat5. It offered the same bandwidth (100 MHz) but was designed to reduce crosstalk and handle speeds up to 1,000 Mbps, making it the first Cat standard capable of supporting the dream of Gigabit Ethernet.

How does a cable ship travel across the ocean?

A ship trails a vast length of cable from a landing station out to sea, while balloon buoys prevent the cable from being damaged or sinking. Good-buoy! As the cable ship gets further out to sea, the buoys are removed and the cable sinks below the water.

How does the Internet travel under the sea?

How the Internet travels under the sea in super-fast cables. The Marea cable will transmit data at 160 terabits per second and stretches from Virginia Beach in the US, to Bilbao in Spain.

How do sea cables get joined?

After travelling great distances to reach a second station or a designated point mid-ocean, the ship meets another cable. A specialist on-ship ‘jointer’ carefully splices the two together, then the conjoined cable is released and buried beneath the seafloor.

Can you use a cable boat in the ocean?

Cables are safest in deep water where they can rest on a relatively flat seabed, and won’t rub against rocks or be at risk of other disturbances. “The deeper the better,” Clatterbuck said. “When you can lay the cable down in deep water you rarely have any problems. It goes down on the bottom of the seabed and just stays there.”
