PPLICATION OF VISIBLE LASER SOURCE
To ensure the accuracy of measurement, optical connectors should be kept clean.
In the process of measurement, please always avoid looking directly into open
optic fiber, optical output, optical connectors or other laser source, for it might
cause eye injuries.
When locating the breaks and escaping light, eyes should be kept away from optic
fiber for at least 30cm.

Locate a Failure of Connectors with Visible Laser
Source
Optic fiber wearing out often happens near or even inside connectors. It is not easy to
present convincing evidence for such failures. The following instructions may be of some
help.
If visible laser is injected into the optic fiber, however, in the far end, there is no visible
laser output. Normally, those failures occur.
The following can verify those problems.
Reverse the connection of the optic fiber, inject visible laser from the far end, and
visible laser will escape from the break.
