WASHINGTON -- The oversupply of long-haul bandwidth connecting major communications hubs has been well documented. But how much bandwidth has been built within these cities' borders to funnel the long-haul bandwidth to the end user? New data released today by research firm TeleGeography shows that while intra-city network deployments far outstrip demand, the gap between supply and demand is narrower on short-haul connections than in the long-haul market.In the six most competitive U.S. metropolitan markets, intra-city bandwidth totals about 88 Gbps -- 50 percent less than the total long-haul bandwidth connecting through these markets (see Figure 1. Bandwidth by Network Type).The new research also finds that a greater percentage of short-haul fiber is actually lit, widening the gap between potential bandwidth on metro and long-haul networks.  Thus, while a fiber glut may exist on the metro level, it isn't as severe as that on long-haul networks. "This is good news for providers of intra-city networks, who will likely see an end to the chronic oversupply of bandwidth much sooner than long-distance operators," said Director of Research Tim Stronge.Neither short-haul nor long-haul lit bandwidth appears to match up well with actual end-user demand, however. In thetop U.S. markets, business Internet connections totaledunder 4 Gbps for all forms of Internet access -- less thanfive percent of lit metropolitan fiber, and less than three percent of lit long-haul fiber.TeleGeography Inc.
