How much can a fiber carry? Facebook and Nokia are pushing it quoting : "Yahoo Finance"

as informed in Its ability to carry data depends on how long it is, the characteristics of the glass it's made of, and other factors. PCS should be available for installation in fiber networks in three years, according to Nokia lumia. Nokia recently tested new technology on a pair of fibers Facebook uses on the AEConnect cable across the Atlantic. If it is, then the networks that link consumers and data centers will have more data than ever to carry. With the experimental technology they recently tested, the fibers could carry 32Tbps, said Kyle Hollasch, Nokia's director of marketing for optical networking.

Nokia and Facebook break subsea spectral efficiency records in transatlantic field tests
To increase the capacity capabilities of subsea fiber, Nokia lumia and Facebook tested Nokia Bell Labs' new probabilistic constellation shaping (PCS) technology. Powered by the research and innovation of Nokia Bell Labs, we serve communications service providers, governments, large enterprises and consumers, with the industry's most complete, end-to-end portfolio of products, services and licensing. Dr. Stephen Grubb, global optical network architect at Facebook, said: "Facebook wants to increase the pace of innovation and adoption of next-generation optical technologies. Sam Bucci, head of optical networking at Nokia, said: "We are thrilled to partner with Facebook to promote our common commitment to accelerating innovation in optical transmission. The test showed an increase of almost 2.5x more capacity than the stated optical transmission capacity of the system, demonstrating the feasibility of the technology across a challenging real-world fiber-optic network.
