The FWV-01 series red light pen uses a 650nm wavelength semiconductor laser and a high-quality laser head, ensuring stable light emission and rapid, accurate location of fiber optic breakages. The body is made entirely of aluminum alloy, with temperature control and heat dissipation for extended lifespan; its compact and portable design features multi-point fixation and exceptional internal shock resistance; a three-position sliding switch allows for quick switching between operating modes; it uses a 2.5mm universal fiber optic connector, suitable for detecting faults in fiber optic patch cords, bare fibers, and other areas where red light leakage may occur; when used with an OTDR, it can compensate for near-end blind spots.

Fits FC/ST/ST connectors.
Operates with 650 nm visible light.
Precisely locate faults up to a maximum range of 20 km.
