Laser pointer can realize fiber on-off detection
At present, the detection of optical fiber is roughly divided into: single and multi-mode discrimination test of optical cable, generally using fusion splicer test; loss test of optical cable, generally using optical power meter test; optical fiber breakpoint test, generally using OTDR test. In general, red laser pointers are used to test the continuity of optical fibers, but the prices of different red laser pointers on the market vary greatly. Some low-priced products cannot achieve the function of fiber continuity detection, but can achieve fiber optics well. Laser pointers for inspection tasks are often expensive, which increases inspection costs.

The switching circuit is provided with a corresponding lamp color switching button on the surface of the pen body; in the optical circuit, a relay with a Z-contact is provided, and the static contact is respectively connected with the red laser diode and the green laser diode The cathode is connected, and the movement of the movable contact is controlled by the light color switching button of the above-mentioned switching circuit. A laser pointer used to detect the on-off of optical fibers. The external structure of the laser pointer includes its pen body (I) and lamp cover (2), both of which are made of light aluminum alloy with good heat dissipation. The lamp cover (2) is set on the pen The upper end of the body (I) is a detachable threaded connection between the two. The Laser pointer body (I) is equipped with a circuit module and corresponding power components. The upper end of the lamp cover (2) is provided with two left-right symmetrical slots. The light-emitting parts of the red laser diode (3) and the green laser diode are sequentially Stretch out from both.
