Connectivity between 100BASE-TX
and 100BASE-FX Ethernet Media.
In the example figure shown
above, the length of fiber Segment X is
1500m (4920 ft). This is 75% of the
maximum allowable distance for multi-
mode 100BASE-FX fiber full-duplex
media (2000 m) [75/2000 x 100% = 75%]. The length of twisted pair Segment Y is 10m (33
ft). This is 10% of the maximum allowable distance for 100BASE-TX full-duplex twisted-pair
media (100 m) [10/100 x 100% = 10%]. The total of the two percentages (75% + 10%) is 85%,
which is allowable.
