3.9 Fiber-Optic Network with the IM 153-2 FO
In this section we show you a sample configuration of a fiber-optic network without
considering the function performed by the IM 153-2 FO.
Sample Configuration
Figure 3-10 shows an example of how a fiber-optic network is configured with the
ET 200M and the IM 153-2 FO as the slave interface.
Note the following points when using a fiber-optic network with nodes with
integrated fiber-optic interfaces:
The fiber-optic network can be set up as a line or star-type configuration.
If you remove the fiber-optic cable from an integrated fiber-optic interface, the
following nodes will also no longer be accessible:
