Definition of Fiber Exhaust in the Network Encyclopedia.
What is Fiber Exhaust?
Fiber Exhaust is a term referring to the potential saturation of the fiber-optic backbone of the Internet due to the exponentially increasing demand for Internet services.
Another factor contributing to fiber exhaust is the move toward high-bandwidth services such as IP telephony and video multicasting technologies on the Internet.
Strategies telecommunications carriers use to avoid fiber exhaust include the following:
- Creating additional high-speed, fiber-optic backbone lines for the Internet by laying down more fiber
- Using dense wavelength division multiplexing (DWDM) technologies to enable existing fiber backbones to carry additional traffic
- Upgrading existing time-division multiplexing (TDM) fiber backbones to higher bit rates
