A ring topology must be connected from CH1 to CH1 and CH2 to CH2. Only with an uneven number
of FO modules, the cables may be connected from CH1 to CH2 and CH2 to CH1 (only once per ring).
10.2 Delay time
Fiber optic applications require a delay time calculation to adjust the Slottime busparameter in the
configuration of the master(s). To calculate the total delay including the fiber optic modules and extra time for
ring events, use the following formula:
FO
length
= Total length of fiber optic cable in km
FO
delay
= Delay of fiber optic cable per km in bit times (see table)
N
FO-modules
= Number of fiber optic modules in ring
N
delay
= Delay of one fiber optic module (see table)
The above formula can be completed with the values in the following table:
Line with split-up
over the same network
Line structure, mixed multimode and single mode
