I beleive the difference between a switch and a router (optical) is that a switch can shuffle entire light paths from one fiber to another, but the logic for which fiber to use comes from another source.

A router can read the data within the optical packet and change fibers based on the information within the packet.

As such a switch can change fiber based on signals from a router, or if the packets are timed it can send some first down one fiber and then down another (so they can be analyzed by routers running slower than the fiber speed).

Slacker,

I don't know if this will help. I just started reading the article and it seems like it will be a very good read. I think it will be pertinent to your questions:

Slack, an optical switch uses mirrors to bend the light. A router works like a postman, sorting my address. There is no known way that you can sort a light source, so optical will remain in the switch area, and revert to electrical/magetic for routing. This is one reason I am not worried about my Cisco stock.
