Are there new technologies or processes coming that will help address the vulnerabilities or capacity issues?
Modern technology has delivered undreamed of capacity with a single fibre pair now able to carry digitised information (including video) that is equivalent to 150,000,000 simultaneous phone calls. Since a single cable can accommodate many fibre pairs the potential for expansion of the network is huge. Whilst this is good news it is obviously important to avoid “keeping all of the eggs in one basket”, hence the continuing requirement to have several cables installed over a wide diversity of routes and a sophisticated management system that enables the traffic to be almost instantaneously switched in the event of a cable failure.
