My first thought is that they've found a way to cheat on the 1.5. If you can make it work at 1.4, you get down to 52.2ms - but get it *too* low and all your photons leak out the sides. Hmm.. Unless you have a magic core
Hi All. It appears we're discussing theoretical limits of silica-based glass here. The Press Release assertion talks about what a trader might experience. Hm. I would ask Rob Beck to clarify this point and inform whether the stated objective in the release accounts for the many o-e and e-o conversions on the overland part of the end-to-end trader connection, including the handoffs that occur in the NY and London metros. I know that terrestrially, i.e., here in the US, some brokerage firms and large banks (is there any longer a distinction between those two today?:) have used their clout to secure links that are virtually entirely optical in nature on routes that are under a thousand miles, but this is not an option on a submarine system that's intrinsically populated with electronics, never mind the tail sections that assume multiple service providers getting into the act. Rob? Anyone?
