The theoretical maximum diameter of an all fiber Ethernet network is
limited to 4.2 km as defined by the 51.2 ยตsec slottime that is specified for
the round trip-delay budget set by the IEEE 802.3 CSMA/CD protocol.
(Thus, point-to-point link distances are limited to a maximum of 4.2 km.)
This section describes how to define total network size based on the limits
of IEEE 802.3 collision detection.
