Features
Advanced Features
1. Various measurement functions
FID-30R is a device that easily and quickly detects the presence or absence of “Tone signal”, “Traffic signal”, and “ONU signal” without interrupting the light by bending the optical coated fiber*. It supports single-mode and multimode optical fibers. The measurement mode (Normal, Fast, Fine) can be changed depending on the purpose of use and the line conditions.
*It does not mean that all ONUs can be detected. If there is an ONU that is not detected, there is a possibility of analyzing and optimizing the waveform of ONU to detect.
2. No need to change clamp heads
The clamp head can accommodate 250μm single fiber up to 3000μm Jacketed cord, and up to 12-fiber ribbon. No need to change the clamp head depending on the type of optical fiber.
3. External Light Detection
Strong external light such as direct sunlight can cause false detection of “Traffic signal”. When FID-30R detects external light, triangles indicating the light propagation direction are lit on both sides of the LCD screen at the same time. False detection can be prevented by covering the clamp head with your hand to block the external light source.
4. Power Meter for FID-30R
FID-30R is equipped with a power meter. It can measure “Traffic signal” with the wavelengths of 1310/1490/1550nm, as well as the intensity 270Hz/330Hz/1kHz/2kHz “Tone signal”. It is possible to connect various optical connectors by selecting the optical connector head according to the connector type.
