Indefeasible right of use (IRU) is a type of telecommunications lease permanent contractual agreement, that cannot be undone, between the owners of a communications system and a customer of that system. The word "indefeasible" means "not capable of being annulled, or voided, or undone". The customer purchases the right to use a certain amount of the capacity of the system, for a specified number of years. IRU contracts are almost always long term, commonly lasting 20 to 30 years. The communication system can be a wire cable, such as a submarine communications cable, fiber-optic cable, or satellite. An IRU owner can unconditionally and exclusively use the relevant capacity of the IRU grantor’s network for the specified time period.
These contracts obligate the purchaser to pay a portion of the operating costs, and the costs of maintaining the cable, including any costs incurred repairing the cable after mishaps. The right of use is indefeasible, so the capacity purchased is also nonreturnable, and maintenance costs incurred become payable and irrefusable.
The IRU "shall mean the exclusive, unrestricted, and indefeasible right to use the relevant capacity (including equipment, fibers or capacity) for any legal purpose". [1] It refers to the bandwidth purchased after, for example, a submarine cable system has been sealed at the end of construction, and to the maintenance agreement (C&MA) among the owners. It is a way for the owners to capitalize the unused capacity or any unowned capacity, after the system comes into service.
In short, buying an IRU gives the purchaser the right to use some capacity on a telecommunications cable system, including the right to lease that capacity to someone else. Smaller companies that need a leased line between, say, London and New York do not buy an IRU – they lease capacity from a telecommunications company that themselves may lease a larger amount of capacity from another company (and so on), until at the end of the chain of contracts there is a company that has an IRU, or wholly owns a cable system.
Today, so-called IRUs allow a telecom carrier to buy all types of telecom capacity and gear at low rates, typically for periods of 20 to 25 years. Since IRUs are technically rights to a physical part of an underground cable, they can be considered an asset. That means their cost isn't part of a company's operating results, but of the property, plant, and equipment line listed on a firm's balance sheet.
According to The Wall Street Journal , dark fiber was pioneered decades ago by AT&T, when it still enjoyed monopoly power. IRUs allowed AT&T's competitors to gain access to the expensive undersea cables that only AT&T could afford to build. [2] There remains some controversy over booking IRUs as assets in an asset-swap transaction between companies. Since IRU's are technically rights to a physical part of a cable, they can be considered an asset, which means their cost isn't part of the company's operating results, but shows up under tangible assets. The IRU is counted as though it is a part of the physical plant of the business buying the IRU. [2]
The Dark fiber (DF) IRU "shall mean the exclusive, unrestricted, and indefeasible right to use one, a pair, or more strands of fiber of a fiber cable for any legal purpose". With an IRU contractual arrangement the buyer of the IRU can unconditionally, and exclusively, use the fibers of the IRU for a long time period, around 25–30 years. [3]
In this case dark fiber is called "dark" since it has to be lit by the IRU owner, not the cable's owner. The wholesale purchase of dark fiber has normally been accomplished by means of IRUs. Fiber cable owners do not normally sell their fiber but offer IRUs for up to 20 years for unrestricted use. 10 to 25 years corresponds to a typical lifetime of the Optical fiber cable systems. The upfront cost for the purchase of a 20-year IRU can be a one-time investment. It will normally be associated with ongoing obligations for shared maintenance. Usually, the IRU can be considered to be a physical asset, which can be resold, traded or used as collateral.
For regulatory reasons, generally only licensed carriers are allowed access to support structures, and to municipal rights of way.
The IRU contract defines detailed technical and performance specifications for the IRU fibers. More specifically, it includes dark fiber acceptance and testing procedures, the description of the dark fiber physical route, operating specifications for the dark fiber infrastructure, performance specifications (attenuation, Chromatic Dispersion, Polarization Mode Dispersion, Optical Return Loss), maintenance and restoration terms. These terms must be valid for the full duration of the IRU contract. Moreover, it includes specific actions and procedures in cases of changes on the IRU grantor’s fiber network, degradation of fiber performance etc.
A transmission medium is a system or substance that can mediate the propagation of signals for the purposes of telecommunication. Signals are typically imposed on a wave of some kind suitable for the chosen medium. For example, data can modulate sound, and a transmission medium for sounds may be air, but solids and liquids may also act as the transmission medium. Vacuum or air constitutes a good transmission medium for electromagnetic waves such as light and radio waves. While a material substance is not required for electromagnetic waves to propagate, such waves are usually affected by the transmission media they pass through, for instance, by absorption or reflection or refraction at the interfaces between media. Technical devices can therefore be employed to transmit or guide waves. Thus, an optical fiber or a copper cable is used as transmission media.
A dark fibre or unlit fibre is an unused optical fibre, available for use in fibre-optic communication. Dark fibre may be leased from a network service provider.
Renting, also known as hiring or letting, is an agreement where a payment is made for the use of a good, service or property owned by another over a fixed period of time. To maintain such an agreement, a rental agreement is signed to establish the roles and expectations of both the tenant and landlord. There are many different types of leases. The type and terms of a lease are decided by the landlord and agreed upon by the renting tenant.
A timeshare is a property with a divided form of ownership or use rights. These properties are typically resort condominium units, in which multiple parties hold rights to use the property, and each owner of the same accommodation is allotted their period of time. Units may be sold as a partial ownership, lease, or "right to use", in which case the latter holds no claim to ownership of the property. The ownership of timeshare programs is varied, and has been changing over the decades.
A hire purchase (HP), also known as an installment plan, is an arrangement whereby a customer agrees to a contract to acquire an asset by paying an initial installment and repaying the balance of the price of the asset plus interest over a period of time. Other analogous practices are described as closed-end leasing or rent to own.

Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. The standard G.651.1 defines the most widely used forms of multi-mode optical fiber.
Project finance is the long-term financing of infrastructure and industrial projects based upon the projected cash flows of the project rather than the balance sheets of its sponsors. Usually, a project financing structure involves a number of equity investors, known as 'sponsors', and a 'syndicate' of banks or other lending institutions that provide loans to the operation. They are most commonly non-recourse loans, which are secured by the project assets and paid entirely from project cash flow, rather than from the general assets or creditworthiness of the project sponsors, a decision in part supported by financial modeling; see Project finance model. The financing is typically secured by all of the project assets, including the revenue-producing contracts. Project lenders are given a lien on all of these assets and are able to assume control of a project if the project company has difficulties complying with the loan terms.
In a hierarchical telecommunications network, the backhaul portion of the network comprises the intermediate links between the core network, or backbone network, and the small subnetworks at the edge of the network.
A finance lease is a type of lease in which a finance company is typically the legal owner of the asset for the duration of the lease, while the lessee not only has operating control over the asset but also some share of the economic risks and returns from the change in the valuation of the underlying asset.
Asset management is a systematic approach to the governance and realization of all value for which a group or entity is responsible. It may apply both to tangible assets and to intangible assets. Asset management is a systematic process of developing, operating, maintaining, upgrading, and disposing of assets in the most cost-effective manner.
Leaseback, short for "sale-and-leaseback", is a financial transaction in which one sells an asset and leases it back for the long term; therefore, one continues to be able to use the asset but no longer owns it. The transaction is generally done for fixed assets, notably real estate, as well as for durable and capital goods such as airplanes and trains. The concept can also be applied by national governments to territorial assets; prior to the Falklands War, the government of the United Kingdom proposed a leaseback arrangement whereby the Falklands Islands would be transferred to Argentina, with a 99-year leaseback period, and a similar arrangement, also for 99 years, had been in place prior to the handover of Hong Kong to mainland China. Leaseback arrangements are usually employed because they confer financing, accounting or taxation benefits.
An optical ground wire is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning strikes. The optical fibers within the cable can be used for high-speed transmission of data, either for the electrical utility's own purposes of protection and control of the transmission line, for the utility's own voice and data communication, or may be leased or sold to third parties to serve as a high-speed fiber interconnection between cities.
Unity is a Trans-Pacific submarine communications cable between Japan and the United States that was completed in April 2010.
In telecommunications, radio frequency over glass (RFoG) is a deep-fiber network design in which the coax portion of the hybrid fiber coax (HFC) network is replaced by a single-fiber passive optical network (PON). Downstream and return-path transmission use different wavelengths to share the same fiber. The return-path wavelength standard is expected to be 1610 nm, but early deployments have used 1590 nm. Using 1590/1610 nm for the return path allows the fiber infrastructure to support both RFoG and a standards-based PON simultaneously, operating with 1490 nm downstream and 1310 nm return-path wavelengths.
Vermont electric power needs are served by over twenty utilities. The largest is Green Mountain Power, a subsidiary of Énergir which recently also took over Central Vermont Public Service. Together this single company represents 70% of the retail customers in Vermont. The state is a small electricity consumer compared with other states. Therefore, its electricity sector has the lowest carbon footprint in the country. As of 2010, the state had the lowest wholesale electricity costs in New England. Efficiency Vermont engages in aggressive initiatives to cut residential electricity waste, which often identifies other problems that it claims can save hundreds per household per year. Accordingly, Vermont's overall energy bills are also relatively lower than in the rest of the New England states.
