Remember “dark fiber?” Well it’s back.
Quick history lesson for those not familiar with this telecom buzz word. Dark fiber was a hot topic during the dot-com days of the late 1990’s. Telecoms, railroads and other large utilities planned for growth and increased demand of their optical fiber networks by laying down extra, unlit fiber cables. When the bubble burst and advancements such as Wavelength Division Multiplexing (WDM) allowed carriers to get more out of their existing lit cables, network owners began selling off their unused optical networks – thus the term “dark” fiber.
