My experience is that product failure is almost exclusively due to design or manufacturing problems, or customer damage (e.g. floods, ESD). The best resource for this data would be your vendors' RMA departments. > And in terms of all optical interface types, if you want roughly 10Gbps > speed but are agnostic about how, what about OC192C POS interfaces > versus 10Gig Ether? In theory, both MTBF and price will be lower for the simpler technology, but by the same token that simpler technology may not support all the features you need. It's hard to say what's best if you don't list your criteria. S
