Optical fiber identifier is used to detect signal direction and approximate power at any position of SM and MM link.
The direction and frequency of light can be identified without cutting off the optical fiber.The "push to talk" operation mode is adopted to make the operation simple and convenient.It can identify three common signal frequencies: 2kHz/1kHz/270Hz.The approximate optical power value of the measured optical fiber can be displayed.Use No.9 dry battery, low power consumption, small size, easy to carry.
