More bits per fiber is good for everybody I only hope they stick with the old stby of diverse fiber routes because with DWDM you have a lot of eggs in one basket. Always good to see someone with a clue posting... This exact issue was discussed on the NANOG list a few weeks ago. One of the execs at Qwest was caught talking about how they wanted to use their standby routes and fibres to carry live data. It was universally rejected as a terrible idea. Yes, it results in higher utilization rates on expense equipment and fibre routes, but it also ups the ante when things fail and seriously oversubscribes the network.
Of course, on the balance sheet, it looks very nice, so I'd be willing to bet and wouldn't be surprised if Comcast or others followed Qwest's example. |
