Figure 2-7. Sample Configuration Distance Calculation
To make the configuration in Figure
1.Use 4200 meters as the maximum network diameter for a pure fiber network as defined by the 802.3 specification.
2.Subtract the equivalent fiber distance for each intervening ONline Concentrator with a
3.Subtract the fiber equivalent distance for the two
2 - 22 ONline Ethernet
