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.
