What is Dark Fiber?

 The more modern definition of the term "dark fiber" refers to unlit fiber optic cables (AKA: "dark") that already installed in the floor and ready for use but not yet used. Why should unused fiber optic cables be in the ground?

Instead of adding new fiber strands to an existing network, network service providers (NSPs) often install more fiber than is currently needed to meet bandwidth requirements, with the idea of ​​being able to expand operations in the future using "dark optical fiber" cables. "

Therefore, these unlit fiber optic lines are an NSP approach to save time, reduce costs, and make their networks future proof against the growing demand for higher bandwidth capacity.

Dark Fiber Optic By installing additional fiber optic cables, NSPs can maximize their efficiency as building a fiber-optic network takes a lot of time and money. When planning a fiber-optic network, the important thing is to determine the path of the cable. However, there are other obstacles, e.g. B. Grant of approval for the construction of fiber passages and channels. Only when NSPs are authorized to set steps and position fiber can all network elements (i.e., switches, repeaters, etc.) be connected to provide an Internet connection.

With a dark fiber map, the operator can essentially act as a separate ISP and does not have to deal with delays in services that can sometimes affect the typical ISP in the customer relationship.
