Fiber Optics and Fiber Optic Cabling play a tremendous role in enabling the modern Internet. As with much of the Internet it is virtual, virtually unseen. Fiber optic cables have been laid seemingly any and everywhere, on land and under-sea. This article provides links to stories and images of the wonders of fiber optics. The image above is a map of all global under-sea fiber optic cabling.

 

 

Mother Earth Mother Board — First, an article by Neal Stephenson, published in the Dec. 1, 1996 edition of WIRED magazine with the “Epic story of wiring the planet” where he chronicles “the laying of the longest wire on Earth.” It’s a great read, albeit long. (Caveat emptor, don’t let it be TL;DR, it’s better than that.)

Trevor Paglen — Art of Undersea Fiber Optic Cables: Trevor Paglen is an artist whose work spans image-making, sculpture, investigative journalism, writing, engineering, and numerous other disciplines. Among his chief concerns are learning how to see the historical moment we live in and developing the means to imagine alternative futures. In 2014, he received the Electronic Frontier Foundation’s Pioneer Award for his work as a “groundbreaking investigative artist.”

Trevor Paglen: What lies beneath – “We all live under constant covert surveillance. The American photographer’s work seeks to reveal this hidden world.” — An article by Liz Jobey, published in the Dec. 31, 2015 edition of Financial Times.

Trevor Paglen Plumbs the Internet — An article by Tim Sohn, published in the Sept. 22, 2015 edition of The New Yorker magazine.

Submarine Communications Cable catalogs the history of telecommunications cabling from the 1850s to the present and provides the usual bevy of information one would expect from a Wikipedia article.

Porthcurno Telegraph Museum:

The Telegraph Museum — The tiny Cornish village of Porthcurno was once the heart of international telecommunications, boasting the largest telegraph station in the world. Today, the Telegraph Museum Porthcurno is a vibrant and captivating heritage attraction. Discover our World War 2 tunnels, the secret hub of Britain’s wartime communications. Visit the Cable Hut where the underwater cables came ashore. Explore our exhibitions and interactive displays, telling the amazing story of global telecommunications from the first practical use of electricity to how we communicate today, using fibre optic cables that still run beneath the world’s seas and oceans.

Internet eXchange Point (IXP) Toolkit: Our objective is to create sustainable enabling environments so that local communities build their expertise and are “enabled”. This is all about extending the Internet around the globe. This is all about working with others to build technical capacity, and for others to carry-on and build communities capable of maintaining, sustaining, and extending the benefits to other. People who donate their time, build technical infrastructure, and otherwise are keen to train people who will train others. Join that community of experts.

 

 

AT&T Archives: Submarine Cable Systems Development - 1958 Bell Labs
AT&T Tech Channel, Published on Jun 24, 2011

A film from 1958 about the future of broadband submarine cable systems. Emphasis is on the mechanical aspects of cable, repeater, and shipboard machinery development. The need for continuing development work on future broadband cable systems is outlined. The complexity of the project is described and its diverse nature is indicated by the fact that information from the fields of oceanography and microbiological corrosion must be integrated with many types of engineering work on the project.

In 1958, Cable technology had been around for 90 years, but still was in its relative infancy. AT&T had made significant improvements to the technology by incorporating coaxial cable, polyethylene insulation, and vacuum tube repeaters (soon to be transistorized), and through these developments had laid the first transoceanic cable, TAT-1, in 1956. TAT-1 could only carry 36 calls at a time, but also contained a Moscow to Washington DC hotline.

In 1983, fiber optic cables were being developed. By 1988 AT&T was able to lay TAT-8, the first fiber-optic transoceanic cable. It could carry 36,000 calls at a time.

Today the world is encircled by cables, in an ever-increasing net laid above and underground, and under the sea. As of this writing (2011), there are at least 15 undersea cable projects in process around the world, slated to be completed by 2013.
