'10 Gbps, yikes!" writes a senior engineer after reading my story about 10 gig homes in Hong Kong. "Do the customers with 10 Gbps access also own a 1001 Horsepower Bugatti Veryon car? I wish someone would do a blind scientific study of the highest access bit-rate for which 99.5% of customers could not perceive any improvement in service. Of course, speed-test would have to be disabled. At some point, the speed will be limited by other factors: application software, LAN, performance of the customer device, server capacity, or the customer’s visual cortex. Seriously, how fast can you drink from a fire-hose?
Another fascinating statistic would be the highest data rate actually consumed by customers who have an access service with 200 Mb/s or more. This does not mean that marketing higher bit rates is wrong; after all there is a proven market for cars with more than 400 Horsepower." Talking to a reporter could be "career limiting" at the gentleman's company.
What presumably happened in Hong Kong is the vendor (?Huawei) offered PCCW a great deal on 10 gig equipment in order to create a model deployment. Now that the chips for 10 gig are shipping, 10 gig doesn't have to be that much more expensive than 1 gig.
