Specifications
  
1)  Support to detect optical signals
without disrupting traffic;
Based on non-destructive technology;
 
2)  Indicate the signal direction in fiber;
 
3) Detect a variety of optical tones,
270Hz, 1kHz and 2kHz;
 
4) Suitable for 0.25, 0.9, 2.0, 3.0mm
fiber, and no need to replace the clamp
block, more convenient than others;
