1.Guide fiber
Use an guide fiber to figure out the character of connector. By adding this
fiber we could move the fist connector out of the blind area.In the same way we
could use this way to figure out the character of last connector.
2.About guide fiber
Proper length of Guide fiber is 100~1000m, it depends on the blind area of
OTDR. In theory, minimum length of guide fiber should be two times longer
than attenuation blind area , but it should be longer in practice.
