It seems Google (Nasdaq: GOOG-message board)'s plans for world domination include laying a submarine cable in the Pacific Ocean.

    Australia's Communications Day reported last week that the search engine giant is in talks with a group of at least half a dozen carriers that includes Asia Netcom and Telstra Corp. (Pink Sheets: TLSYY - message board). The "Unity" cable would use two separate routes to provide network diversity, although exact landing points are yet to be determined.

    Unity was apparently referred to in a presentation by Mike Saunders, Level 3 Communications Inc. (Nasdaq: LVLT - message board)'s director of business development, at the Submarine Networks World 2007 conference in Singapore earlier this month -- although he did not indicate Google was involved.

    A job listing on Google's Website for "Strategic Negotiator, Submarine Cable" makes it clear the company is mulling a larger role in the subsea space: "These negotiators will work closely with vendors to identify highly cost-effective solutions under the most favorable commercial and technical terms possible. They will also be involved in new projects or investments in cable systems that Google may contemplate to extend or grow its backbone."

    Google has become increasingly active in its infrastructure investments -- buying up dark fiber, peering with telcos and ISPs, making a play for wireless networks, and investing in powerline technology. (See Google: Dark Fiber Story Not So Dark , Google's Own Private Internet, Google Pledges $4.6B for Spectrum, Google Takes WiFi Plan to the 'Hood, Mountain View Gets Free Access, and Google's Powerline Play.)

    Joining a  build a new cable would give Google access to its own capacity at build-cost and enable it to peer directly with ISPs in Asia, where Internet traffic is climbing steadily. It would also be a blow to other capacity providers, for which Google is a major source of traffic.

    According toTeleGeographyInc. 's Global Internet Geography research service, Internet traffic across the Pacific increased 41 percent between mid-2006 and mid-2007.

    Several proposals have already been floated for new subsea projects in the region -- including the Trans-Pacific Express and the Asia America Gateway -- in addition to upgrading cables such as Pacific Crossing-1 and the Japan-US Cable system. (See Carriers Plan $500M Transpacific Link, Telstra Picks ALU for Subsea, Fujitsu Scores Massive FLAG Deal, Southern Cross Picks AlcaLu, Fujitsu Wins Japan-US Cable Deal, FLAG Announces NGN, and Carriers to Connect China With $500M Cable.)

    According toTele Geography,the cumulative effect of all this activity will be to boost lit transpacific submarine cable capacity by 120 percent to 7.2 Tbit/s by the end of 2008.

    Analysts are concerned that such a ramp-up could create a bubble and lead to oversupply, much the same as what happened on the transatlantic route.

    Saunders' presentation at the Submarine Networks conference was titled "Asia Pacific cable builds: another Atlantic waiting to happen?" The program lists such questions as: "Multiple cables have been announced for the transpacific routes... are they all viable and sustainable?" and "Can oversupply be avoided without running into a shortage?"

    Tele Geography analyst Alan Mauld in notes that, although the price of leasing a 10-Gbit/s wavelength circuit across the Pacific is more than 10 times higher than comparable capacity across the Atlantic, "in the face of so many new cables, the transpacific market is in danger of a price collapse similar to that which has plagued transatlantic cable operators."
