Did you know that the internet you use also travels beneath the sea? Apparently, we can use the Internet because of the role of the sea as a ‘place’ to store Internet cables. Not many people know that the backbone of global communication lies deep under the ocean. Submarine communication cables carry 95% of international data traffic. So, how does the Internet travel to our location under the sea? Here’s the explanation:

Submarine Cable
Fiber optic cables are installed on the ocean floor to connect countries or continents. These cables enable long-distance data transmission at very high speeds. Submarine cables span thousands of kilometers, connecting vital landing stations that serve as gateways to global communication.

Cable Landing Station
Submarine cables connect to cable landing stations located on land, which are generally found near the coast. At these stations, signals from the submarine cables are received and then routed to land-based networks, such as fiber optics or other communication networks, before being delivered to Internet service providers.

As a digital infrastructure company in Indonesia, Biznet owns and operates Biznet Cable Landing Stations, also known as Biznet MarinePOP. These critical hubs connect Indonesia’s islands and global networks with high speed fiber optic connections. This enables the delivery of high capacity internet services. Biznet currently operates four MarinePOP locations:
1. Biznet MarinePOP Serang Anyar
2. Biznet MarinePOP Bangka Barat Muntok
3. Biznet MarinePOP Lampung Selatan Kalianda
4. Biznet MarinePOP Banyuasin Sungsang

Internet is One the Way to Your Location
Once the data reaches the Internet Service Provider (ISP), it is then sent through the ISP’s network to your location using various methods such as fiber optics, including Fiber To The Home (FTTH), Coaxial Cable, Digital Subscriber Line (DSL), and wireless connections, where the ISP sends signal transmissions via antennas.

With a strong vision to bridge Indonesia’s digital gap and address the country’s growing demand for larger bandwidth, Biznet continues to develop submarine cables and expand its Cable Landing Stations. This ensures that a faster, more reliable, and affordable internet with expansive bandwidth reaches communities across the nation, delivering the same exceptional quality of connectivity available in Java to regions across Indonesia.

Submarine fiber-optic cables are a remarkable innovation that serves as the foundation of modern Internet connectivity. These cables, located on the bottom of the sea, are highly advanced infrastructure that connects Internet networks between islands, countries, and even continents, allowing for fast data transfer with huge capacity. So, how do these submarine cables manage to transfer such vast amounts of data at high speeds? Here’s the explanation!

Using Fiber Optic as the Main Medium
Made from fine glass or plastic, fiber optic is highly efficient and very smooth at transmitting light. Each fiber in an optical cable can carry a massive amount of data in the form of light signals. These signals move through the core of the fiber at speeds approaching the speed of light, enabling extremely fast and large-scale data transfers. Compared to conventional copper cables, optical fibers also offer much larger bandwidth. Each fiber can carry terabytes of data per second, and with multiplexing technology, a single cable can carry a tremendous amount of data.

Advanced Technologies Driving Performance
The ability to carry terabytes of data per second in submarine cables is supported by a technology called Wavelength Division Multiplexing (WDM), which allows multiple data signals to be transmitted through a single fiber optic using different wavelengths of light. In this way, one fiber optic can carry hundreds to thousands of data channels simultaneously. Additionally, there is a more advanced technology that can accommodate even more data, known as Dense Wavelength Division Multiplexing (DWDM), which has the advantage of being able to provide higher bandwidth. With DWDM, multiple wavelengths of light are transmitted simultaneously through a single fiber optic cable. This allows for a significant increase in the capacity of fiber optic cables where this capability is critical in meeting the increasing demand for high speed and high bandwidth data services.

Biznet Submarine Cable Network
Biznet has recently launched the first submarine fiber optic cable network named Biznet Nusantara Cable System (BNCS-1), that connects networks between Java, Sumatra and Bangka Islands. BNCS-1 network consists of 24 pairs (48 cores) of Fiber Optic using the latest Dense Wavelength Division Multiplexing (DWDM) technology. Each 1 pair (2 cores) of Fiber Optic cable can transmit data of 96 x 400 Gbps = 38.4 Tbps. It means that with 24 pairs, BNCS-1 network has a total capacity of 24 x 38.4 Tbps = 921.6 Tbps. The capacity of this network can be increased in accordance with developments of DWDM technology.

In today’s digital-driven world, the Internet has become an essential part of modern life, whether we are working, studying, or enjoying entertainment such as watching videos or playing online games. While almost everyone relies on the Internet, it’s rare to realize how important the infrastructure that supports a smooth connection is. One factor that plays a big role but often goes unnoticed is submarine cables. Without these submarine cables, the global Internet access we enjoy on a daily basis could be interrupted at any time, and our online activities could suffer. That’s why understanding how submarine cables work to ensure a stable and reliable Internet connection.

The Evolution of Submarine Cables

Submarine communication cables are systems of cables installed on the seafloor to connect stations on land, enabling the transmission of telecommunication signals across oceans and seas. These submarine cables play a vital role in keeping global communication running smoothly, from data transmission to telephone conversations between countries. The first submarine communication cables were laid in the 1850s, with the initial aim of carrying telegraphic traffic. The first major achievement in this was the transatlantic telegraph cable that became operational on August 16, 1858, enabling the first instant communication between continents.

In 1871, submarine cables began connecting almost all the continents of the world, except Antarctica. One notable achievement was the link between Java, Indonesia, and Darwin in the Northern Territory, Australia, which was an important step in strengthening connectivity between Asia and Australia. This was ahead of the completion of the Australian Land Telegraph Line in 1872, which connected Adelaide in South Australia and gradually connected the rest of Australia. These submarine communications cables were not only the first telecommunications infrastructure to connect the continents, but also laid the foundation for the modern global communications system we enjoy today. These cables enable the fast and efficient flow of information around the world, playing a vital role in trade, diplomacy and communication between countries.
