檢視 @DELAY TIME (FIBER) 的原始碼

*The delay time of fiber in the system. If the delay time is -1, means the delay time is depends on the situation.
*Is store as '''delay_time''' in the fortran code.

example
 @DELAY_TIME
 -1

Which mean the system has one laser, and its delay time is depends on the situation.<br>
Formula: ([[@LENGTH]]*1000/light_speed)/[[@TIME_UNIT]]<br>
light_speed = 299792458 (m/s)
