Handheld Visible Laser Source

The emitted red light shows where the fiber is seriously curved, covering breakage and nude fiber location, as well as poorly connected locations. It is useful for testing the blind spots of OTDRs. It is suitable for both single mode and multi-mode fibers. In addition, the practical visible fault locator uses FC, ST and SC adaptors. CW and 2Hz alternative optical output modes are also available.
