You have 3 components that can be comparable with each other or not depending on many conditions: - travel time on fiber - transceiver conversion time - time

You have 3 components that can be comparable with each other or not depending on many conditions: - travel time on fiber - transceiver conversion time - time spent sitting in some buffer. This can dwarf other components on "common" networks! http://www.m2optics.com/blog/bid/70587/Calculating-Optical-Fiber-Latency http://www.m2optics.com/blog/bid/70587/Calculating-Optical-F...
