To determine if the network configuration in Figure
1.Use 4200 meters as the maximum network diameter as defined by the 802.3 specification.
2.Subtract the equivalent fiber distance for each
3.Subtract the equivalent fiber distance for each Fiber or
4.Subtract all fiber cable lengths between the transceivers (450 m + 1000 m + 500 m + 75 m = 2025 meters).
Because the final remaining distance is greater than zero (1235 meters), the network configuration is legal.
Connecting External Network Devices
When connecting Thick or Thin Ethernet segments to an ONline network, you can use an:
❑ONline Ethernet Repeater Module
❑ONline Ethernet Bridge Module
❑External repeater or bridge
❑An IEEE Repeater or ONline Repeater Module each have an equivalent fiber distance of 800 meters
