Underwater Fiber Optic
What is Underwater Fiber Optic?
Underwater fiber optics are a type of cable designed to transmit data in the form of pulses of light over long distances., using a glass or plastic core surrounded by several protective layers. Underwater cables are placed on the ocean floor by ships specialized in their installation., enabling data transmission across oceans and seas at speeds exceeding those of satellites and other technologies.
Technical parameters of Underwater Fiber Optic
1. Fiber Number
Multichannel Cables: Cables may contain multiple optical fibers (For example, between 4 and more than 100 fibras), allowing large volumes of data to be transmitted simultaneously.
2. Transmission Capacity
Bandwidth: Modern cables can reach capacities of several terabits per second (Tbps), thanks to techniques such as wavelength division multiplexing (WDM).
The length of the wave: Data transmission is typically performed at wavelengths in the range of 1310 nm y 1550 nm, which are optimal to minimize attenuation.
3. Attenuation
Signal loss: The attenuation in underwater optical fiber is usually in the range of 0.16 a 0.2 dB/km a 1550 nm, allowing long transmission distances without the need for repeaters.
4. Repeaters
Distance between Repeaters: Repeaters are typically placed every 40 a 100 km, depending on seabed conditions and cable design.
5. Installation Depth
Depth Range: Cables can be installed at depths ranging from a few meters to more than 8000 metros, depending on the route chosen.
6. Coating and Protection
Coating Materials: The cables are protected by layers of materials such as steel, polyethylene and other compounds to resist pressure and corrosion.
7. Operating Temperature
Typical Range: The cables are designed to operate in a temperature range of -40°C to +85°C, ensuring its operation in various environmental conditions.
Importance of Underwater Fiber Optic in Global Communication
The submarine optical fiber is fundamental for global communication, as it allows a fast and stable connection between continents and is much more efficient in terms of bandwidth and cost compared to satellite transmission. Besides, These networks are essential for economic development, since they support digital commerce, telecommunications and data transmission of companies and governments worldwide.
