For years, the fiber-optic communications industry has been awash in spare capacity that sent prices for data transmission plunging. Now, thanks to continued growth in Internet traffic, demand is beginning to catch up with supply in many areas of the active global network.
Still, plenty of inactive fiber-optic lines remain — the majority of the lines put into the ground or underwater have gone unused for years and can be activated on short notice and relatively inexpensively. That means the glut has not come to a definitive end and consumer prices are unlikely to rise. But at the moment, prices for sending data traffic at least appear to be stabilizing, providing a welcome reprieve for companies that operate the so-called backbone of the world’s telecommunications infrastructure.
