2 - 20 ONline Ethernet 10BASE-FB Module Installation and Operation Guide
3. Subtract the known amount of fiber cable between the two
transceivers:
1 km + 1 km + 1 km = 3 km (Rule 5)
4. The remainder is the maximum allowable distance of the link
between Concentrators A and C:
4200 m - 570 m - 3000 m = 630 meters
5. Verify that the optical power budget is able to drive all the link
distances in the example. Because all link distances are only 1 km or
less, this is not a problem.
Example: Network with 8 Concentrators
Figure 2-7 shows a network with eight connected concentrators. Use this
example to determine if the distances between transceivers are all within
the 4200 meter maximum network diameter restriction for Ethernet
networks.
