Fiber Optics Transmission Technology
Physical Bus Characteristics
Figure 1-17 shows an example of a SINEC L2FO network configured as a fiber optic star network
with cascading stars. The star centers are active star couplers AS 501.
The technical terms will be explained in the section that follows.

You can also link two S5-95U programmable controllers point to point directly via a fiber optic
cable, i.e., without using an active star coupler AS 501, as shown in Figure 1-18.
