Hundreds of times per second is relatively fast compared with some public information on existing photonic switches. For example, these products describes a connection times of 50-150ms:

starswitch.com

tellium.com

I have not been able to find information on Lucent's products on their web site or in their technical journal. According to IEEE Computer magazine Lucent and Tellium will release all optical switches in the near future and Lucent, Monterey Networks, Sycamore Networks, and Tellium will release all optical routers this year. Hundreds of time per second seems fast compared with this information, but the sample is admittedly small.

With regard to the speed of a typical LAN or SAN optoelectronic switch these connection or switching times are relatively slow - but these seem to be versions that are very early in the technology. For comparison, these connection times are comparable to latencies of second generation fibre channel switches or later generation ATM switches.
