Wherein, TX_DIS signals represent the low speed serial data signal that proximal device is sent；
Optical Signal represent the optical signal on optical fiber (height represents strong, low to represent weak)；
RX_LOS signals represent reaction signal of the distal end optical module to Optical Signal signals.
When Soft_CLK represents to carry out the ideal that data recovery is used to modulated signal in RX_LOS signals
Clock, this clock can be generated according to the setting of baud rate in UART protocol.
When T_off represents that TX_DIS signals correspondence forbids light output state, the actual light output of optical module is rung
Time delays of the Ying Congyou to nothing；
When T_on represents that TX_DIS signals correspondence allows light output state, the actual light output response of optical module
Time delay from scratch；
T_lose_on represents optical signal from having to during the change of nothing, and RX_LOS signal designations are lost for optical signal
The time delay of mistake；
When T_lose_off represents that optical signal changes from scratch, RX_LOS signal designations be optical signal just
Normal time delay；
T_delay represents the propagation delay time of optical signal in a fiber；
T_setup1 represents that (it is " 1 " that correspondence proximal device sends logic level to RX_LOS modulation datas 1
Low speed serial data) sampling setup time, it is desirable to T_setup1>0；
T_hold1 represents the sampling retention time of RX_LOS modulation datas 1, it is desirable to T_hold1>0；
T_setup2 represents that (it is " 0 " that correspondence proximal device sends logic level to RX_LOS modulation datas 2
Low speed serial data) sampling setup time, it is desirable to T_setup2>0；
T_hold2 represents the sampling retention time of RX_LOS modulation datas 2, it is desirable to T_hold2>0；
It is represented by based on the maximum transmission rate of this scheme：Min (clock cycle)=Max
(T_off+T_lose_on, T_on+T_lose_off).
