Frank, You seem to have a handle on the technicals of Photronics, which I am lacking. Can you clarify a couple of things for me? My basic assumptions from limited knowledge.... Cien and SR are through put enhancing along a single glass fiber ie. Straight line technology? TLAB touts their digital cross connect switches...Are they fully optical or do they need to convert from op to electrical signal? Does this slow through put, can they be remotely configured in the event of a physical problem w/ the fiber...cut fiber to prevent a problem as AT&T had recently? What happens at the router ie. w/ CSCO....Optical to elect? Does anyone have in the field or in Lab testing a fully optical switch or router? This was quick,off the top of my head..and maybe not well thought out, however, if you can make anything of these basic questions it would be appreciated....Thanks Stan
