Progressive Innovation of the proven Ethernet-Technology, retaining the following features

Benefits of Fast Ethernet

Data formatAccess mode CSMA/CDSame cables for Twisted Pair and Fiber Optics

Higher transmission rateUsage of switching technology: load separationSimple network configurationHigh Speed Redundancy: Reconfiguration time <0,3 secAlso for big networks! - up to 150kmProtection of the investment, 10 Mbit´s networkstructures can be easily integrated
