Undersea Network Procurement: A List of the Advanced Technological Components of Underwater Fiber Optic Cables

The first key component of an undersea fiber communication system is the one at its core: the lightweight cable. The
lightweight cable, composed of fibers and polyethylene insulators, serves as the core for all of the armored cables in the system. This lightweight cable runs through all of the following mechanical pieces.

The combination of the armored and lightweight cables run through the undersea cables, which should theoretically contain and protect the optical fibers and electrical conductors for over 25 years. The designs of these underwater cables must meet the industry safety standards, at least to withstand the stresses of temperature, pressure, torsion and chemical exposure of a deep sea environment.

Moving on, repeaters are the small devices which repeat along the length of the cable. Undersea repeaters provide electrical power to the undersea fiber communication system. To perform, these repeaters must be qualified to operate at the voltages and currents provided by the power feed equipment. They must be designed to withstand typical marine operations, including system laying, burying, recovery, and repair procedures, while maintaining its performance and reliability objectives throughout the system’s
design life.
Branching units are the final basic components of Undersea Fiber Communication Systems, on which even a layman like myself can picture an undersea cable in realistic detail. Branching units coordinate Fiber routing between 3 locations, maximize the number of express paths for largest bandwidth paths, combine smaller
bandwidth-demand generators to as few pair as possible, and typically cost a project small incremental amounts along the life cycle of an undersea network.

Located close to the beach, branch units connect branches of wires to the main unit which spans the floor of the sea.
Methods for Enabling Undersea Network Procurement

Firstly, traditional consortium, private ownership or hybrids of two are the main means of undersea network procurement.To finance your project, you will need to cover the construction costs of dry equipment, installation and testing for both marine and dry equipment, project management, training, documentation, as well as the maintenance of terminal station buildings. Your project startup costs will cover licenses and permits (including environmental), legal and finance. Your technical costs will include backhaul as the cable station to service providers and the onward connectivity (the capacity cost to reach a global network).

Be aware also that your Undersea Network Procurement may take 12-24 months to plan and construct depending on the length of the cable or the complexity of local financial institutions. But with the right research or by investing in a business partner who can help you find well=proven products that perform for decades, you will be able to also procure and install an undersea network.
