Frank & Thread, the following statement from lightreading about the Core-Tek tunable laser has aroused my curiosity. Core-Tek claims their laser has switching speeds measured in nanoseconds. The article suggests that packet by packet routing becomes possible at these speeds. Sorry I can't give you a link because I received the article by email without a link. I posted the article on the NT thread at: Message 13270661 What are you comments about whether packet by packet routing might be possible at the optic layer? Here is the quote: Why the big interest in switching speeds? Because tunable lasers might end up replacing cross-connects in carrier networks, and might even go a step further and make it possible to switch light on a packet-by-packet basis in the longer term future (see Researchers Unveil All-Optical Advances ). In general, one millisecond is fast enough for protection systems - automatically setting up alternative wavelengths to route traffic around failures. When switching speeds go down to nanoseconds, packet-by-packet routing becomes feasible.
