The Unenforceable Use Right (IRU) is a kind of permanent telecommunications lease that cannot be cancelled between the owners of a communication system and a customer of that system. The word “unenforceable” means “not being able to be declared or unreported or cancelled.” The client acquires the right to use a certain amount of the system`s capacity for a number of years. IRU contracts are almost always long-term and usually take 20 to 30 years. The communication system can be a wire cable. B, for example, an underwater communication cable, a fibre optic cable or a satellite. An IRU owner may use unconditionally and exclusively the corresponding capacity of the IRU`s network of beneficiaries during the specified period. An unachievable right to use (IRU) is a contractual agreement between the operators of a communication cable, such as the u-priming communication cable or the fiber optic network, and a customer. In the telecommunications field, the Undefeasible Right of Use (IRU) is the effective long-term lease (temporary ownership) of part of the capacity of an international cable. IRUs are shown for a number of channels of a given bandwidth. IRU is granted by the company or consortium of companies that built the cable (usually fiber optic).

Some legal agreements of the IRU prohibit the resale of the ownership of the capacity. At least one large international cable owner has 25 years to own the IRU. Think about it, if you rent an apartment, sign a contract with the landlord as a tenant. You cannot rent this apartment to someone else. It`s a bit like leasing. But if you are the owner, you can rent it to anyone you want. This is an example of unachievable user rights. The Impractical Right of Use (IRU) is a permanent contract, which cannot be cancelled between the owners of a cable and a customer of this cable system. Cable is usually a fiber optic cable because fiber optics can transmit more data than any other type of media.

The IRU “means the exclusive, unlimited and unworkable right to use the relevant capacity (including equipment, fibre or capacity) for any legal purpose.” [1] It refers to the bandwidth purchased, for example after the sealing of a submarine wiring system at the end of construction, and the maintenance contract (C-MA) between the owners. This is a way for homeowners to use unused capacity or any unused capacity after the system is put into service. An IRU gives a large Internet service provider (ISP) the opportunity to provide long-term international service to its own customers. These contracts require the purchaser to bear a portion of the operating costs and maintenance costs of the cable, including the costs of repairing the cable following an outage. The right to use is unfeasible, so that the acquired capacity is also not refundable and the maintenance costs incurred become payable and irrefutable.
