Google job ad looks for the dark side

Is Google planning to build a global fibre optic network from scratch? And, if so, why?

The question has cropped up in light of a recent job posting on the search engine giant's website seeking experts in the field.

"Google is looking for Strategic Negotiator candidates with experience in...(i)dentification, selection, and negotiation of dark fibre contracts both in metropolitan areas and over long distances as part of development of a global backbone network," the posting reads, in part.

Dark fibre refers to fibre optic cable that's already been laid, but is not yet in use. Thousands of miles of dark fibre is available in the United States, but there have been few takers due to the high costs of making it operational.

A Google spokesman declined to elaborate on the job posting. Still, it raises some tantalising thoughts, including the long-shot chance that the company is laying the groundwork to jump into the telecommunications business. The posting was reported by Light Reading, a website that tracks the optical networking industry.

If Google were to build its own global or national fibre network, the project would likely cost billions of dollars and take years to implement, an investment that would be hard to justify based on the networking needs of most companies. Renting "lit" fibre from carriers is generally a cheaper, and therefore preferred, way to go.

Google is thought to be a shrewd judge of computing value, having built its widely admired infrastructure on the back of low-budget server clusters. At the same time, curious geeks have long pondered the apparent mismatch between its service demands and the reputed scale of its computing resources.

A handful of dark-fibre projects have been gaining momentum recently, mostly involving large consortia of private companies, universities and medical facilities, sometimes with heavy government backing. Best-known is the national LambdaRail project. According to Steve Corbato, the director of network initiatives for Internet2, -- a member of the LamdaRail project -- his company's FibreCo subsidiary has bought up some 28,000 route miles of dark fibre.

Corbato also declined to speculate about Google's plans. But he said fibre optic expertise is a natural fit for a company like Google.

"If I were the CIO of an international information technology company, I would think that having these types of skills would be a natural to have within the organisation."

A Level3 spokesman declined to comment when told of Google's job posting.
