Dark Fiber Increases Network Capacity

Many people have not heard of Dark Fibers or Unlit Fibres that are really just unused optical fibres. These are utilized in what is known as fibre optic communications. Dark Fiber (Fibre) was first utilized when speaking about the network capacity of telecommunications and its infrastructure. Presently, it includes a reference to the increasing utilization of leasing fibre cables from any market related service provider in the network.
Let's examine the reasoning, logic, rationale, logistical practicality and market of the Network's Capacity of Telecommunications' Infrastructure.
A. Unlit Fibre Capacity And/Or Expansion.
Reasoning: Dark Fiber is found in well prepared, planned and constructed networks. The budget to install falls within the ambit of the civil engineering required. This labor includes preparation, planning, costing, routing, obtaining permission from relevant stakeholders, creating ducts and channels to lay the cables, and finally installing and connecting these optic fibre cables. It accounts for 60%+ of the cost of network development. It is thus economical to install more unlit fibre than what is needed for the prevalent market demands to prepare for expansion and redundancy.
B. Over Capacity of Unlit Fibre:Telephone companies were the builders of optical fibre networks; each with a business plan and intent of addressing the telecommunications market. This was based on the motivation that telecommunications/telecoms traffic, especially data traffic, would continue to increase as the network market inevitably would. Wavelength Division Multiplexing (W. D. M.) availability further encouraged reductionism in the demand for fibre because of the increased capacity that could be placed on a single fibre. The cost of data traffic collapsed. A number of providers filed for bankruptcy protection calling for a new telecommunications market.
C. Existing Market Trade:Local exchange carriers wouldn't sell unlit fiber to end users because they believed that it would distract some of their other more viable services. Incumbent (U. S.) carriers, being compelled to sell to competitive local exchange carriers sold this commodity as Unbundled Network Elements (U. N. E.). Since then, they have successfully lobbied reducing what is provided for existing fibre and cut it out completely for new deployments of fiber to the premises (F. T. T. P.).
Local Carriers in competition, in turn, were not required to sell this product, although unlit fibre exchanges between these local competitive carriers are common practice. The reach of the network increases in places where many a competitor has an influential presence, in exchange for provisions of unlit fibre capacity in places where that competitor has no influence.
Specialist companies arose. Dark fiber became a more readily available commodity during the late 1990's through to 2001. Pressurizing demands later lessened with capital being reinvested in order to light up existing dark fibre.
Dark Fiber capacity is commonly utilized by network operators with the intention of building S. O. N. E. T. And Dense Wavelength Division Multiplexing (D. W. D. M.) networks. By end-user endeavors for the expansion of local area Ethernet networks. D. W. D. M. Availability and accessibility is quickly and inevitably decreasing the cost of networking; Further progression is inevitable. It is thus no surprise that dark fiber appears to be lighting the network capacity of the telecommunication infrastructure.
