GAO811 handheld visible laser source is visible red laser source, which is mainly used in finding fiber faults accurately. The laser could not only be reflected out from the seriously bend point, overlay layer or the naked fiber position, but also can be jetted from the tie-in which is not linked well. It can distinguish the faults of fiber jumper, jumper board, distribution frame and tie-in. Meanwhile, the visible laser source can remedy the limitation of the near blind area of OTDR, and judge fiber faults position accurately as an ideal instrument for optical net function and maintenance.
