Show the current state value of updated light-path.For three road light-pathes, every road light-path be it is independent, do not cooperate mutually,
Electric current is individually balanced, therefore the FS of first via light-path is the state value transmitted in T1 after fabc, the FS of the second road light-path
For the state value after fabc in transmission T2, the FS of third road light-path is the state value transmitted in T3 after fabc.For two
Road light-path, all the way light-path be transmit fa in T2 again after the fabc first transmitted in T1, therefore transmit the fabc in T1 it
State value afterwards is the state value before the fa transmitted in T2, and therefore, the FS of this light-path all the way be the state in transmission T2 after fa
Value；Another way light-path is to transmit bc in T2 again after the fabc first transmitted in T3, therefore after transmitting the fabc in T3
State value is the state value before the bc transmitted in T2, and therefore, the FS of this light-path all the way be the state value in transmission T2 after bc.It is right
In light-path all the way, light-path is first to transmit the fabc that the fabc in T1 is transmitted in T2 again later to transmit in T3 again all the way for this
Fabc, therefore the state value after the fabc in transmission T1 is the state value before the fabc transmitted in T2, transmits the fabc in T2
State value later be transmit T3 in fabc before state value, therefore, this all the way light-path FS be transmission T3 in fabc it
State value afterwards.
