步进可调光延迟线
2*2 adjustable ODL
可调延迟线采用数字可调式延迟线工作原理,通过2x2 光纤光开关实现二进制距离权位的取值设置,通过不同长度的光纤延迟线长度实现二进制距离权位取值,高步数>2047m。
The adjustable delay line adopts the working principle of digital adjustable delay line. The value of binary distance weight is set by 2x2 optical fiber optical switch. The value of binary distance weight is set by different lengths of optical fiber delay line, with the maximum number of steps > 2047m.
