Optical Fiber Identifier FID-30R/31R/32R
Applications
- Detecting the presence or absence of light in optical fiber cores.
Features
- 01
Various measurement functions

By simply pinching the optical fiber, the presence of tone, traffic, and ONU signals can be detected without interrupting the line.
- 02
No need to replace bent parts

The bending tip accommodates fibers from 0.25 mm single fiber to 3 mm cord, as well as up to 12-fiber ribbon.
- 03
Power meter function (FID-30R only)

Measures communication wavelengths of 1310, 1490, and 1550 nm, along with fiber reference signals at 270 Hz, 1 kHz, and 2 kHz.
Customer Benefits
Detection is performed by simply clamping the fiber or cord, enabling fast, non-intrusive measurement without interrupting the line. Compatible with single- and multimode fibers, the unit offers standard, high-speed, and high-sensitivity modes to suit different applications and line conditions.
