How Does Sri Lanka Connect To The Internet?

Internet in Sri Lanka is not from satellites? Then how

The way the Internet came to Sri Lanka … We all thought it was from satellites.

Submarine Cable – How the Internet Comes Through the Sea

Do you know how to get internet in Sri Lanka? Not from satellites. Sri Lanka is an island and is connected to the world by a few cables drawn along the seashore. These are called submarine cables. This is it.

SEA-ME-WE

SEA-ME-WE (LIMITED) is the largest cable system in Sri Lanka. SEA-ME-WE Characteristics of Syllables – Southeast Asia – Middle East – Western Europe. This cable system extends from France to Singapore. Every company in the country (SLT in Sri Lanka) invests in these cables. The capacity of the cable system depends on the size of the investment. SEA-ME-WE 1 to 5 cable systems are available at sea.

Copper Cables

Long ago these submarine cables were made of copper. A little less than a foot in diameter. The first cable to Sri Lanka was SEA-ME-WE 1. Thin copper. This was near the Colombo Golf Course. SLT owns this right from Sri Lanka. After a while, the capacity was running out. So those countries got together to build the SEA-ME-WE 2 system. This too is copper. The difference was that there were 2 cables in this one. The frequency is divided by two. This is connected to the golf course. Due to the high cost, lack of speed in the future, and the arrival of optical fiber, copper wires such as SEA-ME-WE 1 and SEAMEWE 2 all died.

Fiber Optics..

Then came the submarine cable, all the fiber optics. First, let me briefly describe what fiber optics are.

First of all, there is no wire inside the fiber optics. There are very thin glass eyes. So how do you exchange data along this?

Very simple. Any data can be represented by a binary number such as 0110101001. You’ve seen it in movies. Data can only be transmitted in one and a half drops. Think of it this way. You’re on one side of the river. Your friend is on the bank. You need to send him 0111010. All you do is use a torch. If the torch is inactive, then 0. Off (0) On (1) On (1) On (1) Off (0) On (1) Off (0) sends 0111010 to a friend on the bank. Now he has to decode the number of binaries and find out what you sent.

The same is true of optical fiber. A high-speed laser beam is sent along the glass beams. To turn this on, we can see that 1 and 0 are the other way around. This is a fast transmitting of data. Copper wire cannot be turned at this speed. So over time the submarine cable switched to fiber. The old copper cable was left in the middle of the sea.

Submarine cables.

There are several submarine cables coming to Sri Lanka. It’s all fiber.

• SEA-ME-WE 3 – This landing station is in Mount Lavinia. Because of the old, this will stop the operations. SLT owns the rights in this country

• SEA-ME-WE 4 – This is the golf course going across the ocean like a black reed. Don’t forget to take a look at SEA-ME-WE 1 and 2 as well. This too is owned by SLT. Most of the work in this country was done by this.

• SEA-ME-WE 5 – This is the latest and fastest. The speed of one wavelength is 100Gbps. It can send 80 wavelengths. Then the full speed is about 8 Tbps. But 80 wavelengths in Sri Lanka will not be used for at least another 10 years. So the maximum speed would be 600 Mbps. The landing point is Matara. Sri Lanka belongs to Sri Lanka

• Dhiraagu – This is not a round the world. This is a point-to-point connection. This is where Sri Lanka and the Maldives connect. SLT is the right of Sri Lanka

• Bharat Lanka – This is point to point. This is Sri Lanka’s tuticorin in India. SLT is the right of Sri Lanka.If there was an error in Sections 3 and 4 before the SEA-ME-WE 5 came to India through Bharat Lanka, we were connected to the world.

• Bay of Bengal Gateway (BBG) – This is going from UAE to Singapore. Dialog’s ownership in Sri Lanka. The maximum speed is said to be 6.4 Tbps. The Landing Station is in Mount Lavinia.

At present, only six of these submarine cable systems are connected. Of this, 5 belongs to SLT and 1 to Dialog.

What’s it like to sail across the sea on these submarine cables?

These maps are the trajectory of some of those submarine cable systems

They usually go under the sea. These cables are installed and maintained by separate international companies including ships and divers. They are the ones who command the sea through submarine cables.

Does a laser light go that far?

When we hit a torch the maximum distance the torch will light. Someone farther away doesn’t see the torch. The same goes for the laser light that goes along with the fiber optics (this is not an illusion. This laser light has the maximum distance it can go. There’s no getting out of there. What do you do then?

That’s when the repeaters come to our aid.

These repeaters are all over the sea. The task is to increase the strength of the weak laser beam and send it back to the next stop along the cable. The optical amplifiers in the repeater are used for that.

Damage to Submarine Cables

• Occasionally, ships sail and sail. When an anchor is inserted into our submarine cable, the cable breaks\
• Submarine cables are not cheap though a normal fiber is thin. The reason is that the fiber’s safety is all around it. Looking at this cross section, you can see how much protection there is around the thin fiber.

One armor is the armor. This is a metallic cover. It is this metal armour that transmits the power required to repeaters. As electricity travels along a conductor, it creates a magnetic field around it. This is so. Here’s a magnetic field a few people mistake. That’s sharks. They think that this is a prey and they break the cable.

Those 2 are the major damage to submarine cables. So even if one of the cables is in danger, there is no reason to worry that Sri Lanka will lose the internet because we have so many more cables.
