DARK FIBER (FIBER OPTICS) - Research Paper mannikinThey also withstand ambient temperatures.Dark role, just as it sounds refers to unlit fiber as no light runs through it. According to Lovink (p. 226), it is an optical fiber infrastructure that has been installed but remains unused. This could be in camera operated and run directly by an operator who leases it to a nonher supplier who would instead not purchase hired line or bandwidth capacity. Hence, fiber could still be considered as dark if lit by the lessee and not the owner. This fiber is not connected or controlled by a phone company but rather an individual or company provides the required components for it to function.Dark fiber provides telecommunication operators with the ability to choose the engineering science that would be appropriate to them, whether SDH, fiber channel Ethernet or ATM without the need to construct an entire cyberspace infrastructure or even having to rent a managed service from an operator who ot her that being costly could also be a competitor. Dark fiber has also been used in networks for dense wavelength percentage multiplexing (DWDM) as pointed by Rodriquez. The reason that dark fiber would exist in sufficiently planned networks would be because of the initial cost involved in installing cables, particularly civil engineering. The accompanying activities encompass planning, obtaining permission, routing, creating transmit and ducts for the cables, installation and connection. Wagter claims that this would constitute over 60% of development cost pointing out at Amsterdam where this was at 80% with only 10% going to fiber. Therefore, it becomes more economical to plan and install more fiber than the current demand so as to give allowance for future expansion and security in case any cable fails (Lovink, 230).In the US, local exchange carriers avoided selling dark fiber to the reverse users fearing that it would eat into their other lucrative services. It was a requirem ent that they sell this
