In the industry of submarine cables, “spectrum cable internet sharing” refers to the practice of assigning distinct portions of the optical spectrum carried by a cable to various end-users. This procedure results in the creation of independent “virtual fiber pairs” for each customer. This strategy enables the effective exploitation of cable capacity and gives the end users with the flexibility to scale their usage according to their specific requirements.
IT Operations
This idea of virtualization is similar to how it has transformed IT operations in companies, by moving away from an approach that is dependent on hardware and towards a software-based system that enables multiple users to share a common platform, which in turn results in cost savings and optimal asset utilization.

Additionally, this method makes it possible to dynamically allocate the spectrum.
Management of the Spectrum
This gives users the ability to use the spectrum just when they require it and to let it go to waste when they are not making use of it. Additionally, it enables the effective management of the spectrum as well as the prevention of interference among the various users. In a nutshell, spectrum sharing is a technology that allows several end-users to access the limited undersea optical spectrum in a manner that is both dynamic and adaptable. This method is both cost-effective and efficient.
Spectrum sharing is a method that enables the effective utilization of the limited undersea optical spectrum by partitioning it among numerous end-users. This makes it possible for more people to make use of the spectrum. This strategy is adaptable to both traditional C-band cables and more recent, wider-band cables that handle both C-band and L-band on the same cable at the same time. Because newer, uncompensated submarine cables have a wider repeater bandwidth, it is easier to implement the capability of virtualizing a fiber pair on these cables.
Result
As a result, there is more spectrum that is available and may be shared by more end users. This allows for the dynamic allocation of the spectrum, enables users to access it only when needed, and makes it available to other users when it is not in use. It also makes efficient administration of the spectrum easier to accomplish, and it decreases the likelihood that different users would interfere with one another.
