The Cable Industry
March 6, 2013
On a recommendation from someone, somewhere (the exact source has escaped me; another issue of my infinite reading list – see below), I just finished reading an article from the December 1996 issue of Wired about the laying of transoceanic cables (Mother Earth, Motherboard, 4.12).
This article, written on the cusp of the internet revolution, describes a cable being run from Cornwall to Japan, crossing over land, but mostly buried at the bottom of a very complicated ocean. The writer, who describes himself as a hacker-tourist back when few people knew what hackers were to begin with, focuses on the technology that made these transoceanic cables possible.
But one particular part of the article hit home to me. For five of the last six years, I have worked for a cable network (the television kind). In one of the myriad positions I have held at this company, I used to request out of town, and sometimes international, video feeds.
In 2013, there are multiple ways we get these feeds. Some come off of a satellite dish in the sky. Some come to use via FTP (across the web). Some still come to us via microwave signals, which require a line of sight. Our newest technology is video feed via cellular signal, which, as a new technology, is spotty at best. But the vast majority of our coverage, from across the street at the U.S. Capitol building to across the ocean in London, comes to us via fiber link, or physical cable.
I have booked fiber feeds and cross-connects too numerous to count, but I never really thought about what this meant until I read this article from 1996. There are literally cables running across the ocean, carrying the BBC’s coverage of the British House of Commons to my building in Washington, D.C. There are cables in the White House and in the Capitol, there are cables in most of the “think tanks” and in the State Department and Pentagon.
There are buildings, like the one the author describes in Alexandria, Egypt, where people literally connect this fiber coming in from one location to one going out to another location, creating a world encircling network of fiber cables.
In the modern era, we take for granted that these fiber networks work, and have significant built in redundancies to prevent an interruption of service. But not so long ago, at a time in most of our lifetimes, this was not guaranteed. It amazes me to think that these systems only exist because a very talented team of engineers, cable layers, and sailors physically laid the cable that enables our nearly instantaneous around-the-world communications.
What amazing everyday feats of engineering and science are we performing right now that children born today will completely take for granted? What will we be unable to live without?
