有所不同的是，这种激光器与其它脉冲激光器完全相反：在大多数的时间里它是打开着的，但它会周期性的短暂自动关闭。
What is unusual is that this laser is the exact inverse of most pulsed lasers: it's on most of the time, but periodically turns itself off for a short time.
对于SDH应用，规定了一种横向兼容激光器自动关闭和再启动程序，此外，还对IEC60825光安全标准做了说明。
For SDH applications a transverse compatible Automatic Laser Shutdown and Restart procedure is specified. Furthermore a clarification of the IEC 60825 standard on optical safety is provided.
