HOW DO WE GET INTERNETS ?
The internet is an essential part of modern life, providing access to information, communication, entertainment, and countless services. But have you ever wondered how the internet actually reaches your home or device? Understanding the infrastructure and processes involved can give you a deeper appreciation of this vital technology.
In the world everyone have to know this how internet works
In this world everyone had thought internet is working from satellite to tower through these connection is working but that's absolutely wrong because.............
The backbone of the internet consists of high-capacity fiber-optic cables and network nodes that span the globe. These backbones are owned and operated by major telecommunications companies and are the primary conduits for data traveling long distances.
To deliver the internet to homes and businesses, ISPs use a combination of wired and wireless technologies. These include:
- Fiber-Optic Cables: Provide high-speed internet by transmitting data as light pulses through glass fibers.
- DSL (Digital Subscriber Line): Uses existing telephone lines to deliver internet.
- Cable Broadband: Utilizes the same coaxial cables that deliver cable TV.
- Satellite: Provides internet to remote areas via satellites orbiting the Earth.
- Wireless Technologies: Includes Wi-Fi, 4G, and 5G networks.
Now everyone have the doubt definitely How the internet cables are works under the sea ?
Your thought was right , the fiber cables are inserted by people under the sea.
Undersea fiber-optic cables, often referred to as submarine cables, are a critical component of the global internet infrastructure. These cables lie on the seabed and connect different continents, enabling high-speed data transmission across vast distances. They are essential for international communication, data transfer, and global connectivity.
1. Fiber-Optic Cables
Core Components:
- Optical Fibers: Thin strands of glass or plastic that transmit data as light pulses. The core and cladding of these fibers are designed to keep the light signals contained within the fiber for efficient data transmission.
- Cladding: Surrounds the optical fiber core and reflects light back into the core, maintaining signal integrity and minimizing loss.
Protective Layers :
- Primary Coating: A plastic coating that protects the fibers from physical damage.
- Strength Members: Steel wires or Kevlar strands that provide mechanical strength and protect against stretching and breaking.
- Metallic Shielding: A copper or aluminum tube that provides additional protection and can conduct electricity to power repeaters.
- Waterproofing: Layers of waterproof materials to prevent water ingress, which could damage the fibers.
- Outer Sheath: The final protective layer, often made of polyethylene, which shields the cable from environmental damage and mechanical stress.
2. Repeaters (Amplifiers)
- Function: Repeaters are installed at regular intervals along the cable to amplify the light signals, compensating for signal loss over long distances. This ensures that data can travel thousands of kilometers with minimal degradation.
- Power Supply: Repeaters are powered by electrical currents sent through conductive elements within the cable, typically a copper or aluminum sheath.
3. Cable Landing Stations
- Purpose: These are facilities where the undersea cables connect to the terrestrial network infrastructure. They house the equipment needed to process and route the data to and from the undersea cables.
- Components: Includes power feed equipment, monitoring systems, and connection points to the terrestrial internet backbone.
4. Power Feeding Equipment
- Role: Supplies the electrical power required by the repeaters along the cable. This equipment is located at the cable landing stations and ensures a continuous and stable power supply throughout the length of the cable.
5. Branching Units
- Function: Used to split the main undersea cable into multiple branches, allowing connections to multiple destinations from a single main cable. This is useful for connecting island nations or coastal areas to the main international network.
6. Marine Survey and Route Planning
- Surveying: Detailed marine surveys are conducted to map the seafloor and identify the best route for laying the cable, avoiding hazards like underwater mountains, coral reefs, and shipwrecks.
- Planning: The route is carefully planned to ensure the cable is laid in a safe, stable environment, minimizing the risk of damage from natural and human activities.
7. Cable Laying Ships
- Vessels: Specialized ships equipped with large spools of cable and precision equipment to lay the cable on the seabed.
- Operation: These ships deploy the cable according to the planned route, carefully monitoring its placement using GPS and sonar to ensure accurate and safe deployment.
8. Cable Protection and Burial
- Plowing: In shallow waters, cables are often buried beneath the seabed using plows or remotely operated vehicles (ROVs) to protect them from anchors, fishing activities, and other potential hazards.
- Armoring: Cables are armored with additional protective layers in areas where physical damage risks are higher.
9. Monitoring and Maintenance
- Real-Time Monitoring: Systems are in place to continuously monitor the performance and integrity of the cable, detecting any faults or issues.
- Repair Ships: Specialized ships are deployed to repair and maintain the cables when damage occurs, ensuring minimal disruption to service.
