Changes of string in 31165: In the late 1980s, 10 Mbps became too slow for some applications and network manufacturers developed several LAN technologies that offered higher bandwidth, such as the 100 Mbps FDDI LAN that used optical fibers. As the development of 10Base5, 10Base2 and 10BaseT had shown that Ethernet could be adapted to different physical layers, several manufacturers started to work on 100 Mbps Ethernet and convinced IEEE to standardize this new technology that was initially called `Fast Ethernet`. `Fast Ethernet` was designed under two constraints. First, `Fast Ethernet` had to support twisted pairs. Although it was easier from a physical layer perspective to support higher bandwidth on coaxial cables than on twisted pairs, coaxial cables were a nightmare from deployment and maintenance perspectives. Second, `Fast Ethernet` had to be perfectly compatible with the existing 10 Mbps Ethernet to allow `Fast Ethernet` technology to be used initially as a backbone technology to interconnect 10 Mbps Ethernet networks. This forced `Fast Ethernet` to use exactly the same frame format as 10 Mbps Ethernet. This implied that the minimum `Fast Ethernet` frame size remained at 512 bits. To preserve CSMA/CD with this minimum frame size and 100 Mbps instead of 10 Mbps, the duration of the `slot time` was decreased to 5.12 microseconds. @ Weblate
