* Required Fields

The FF-3306G Optical fiber identifier is used to detect signal direction and approximate power at any position of SM and MM fiber link.
During the maintenance, installation and cabling, it is often necessary to find or identify a specific optical fiber without interrupting the working signals in fiber.
FF-3306G identifier is used to identify the modulation (270Hz/ 1kHz/2kHz) signals that is injected into the optical fiber at one end
Direction & Intensity Weak optical signal is revealed when optical fiber is bent, and the direction and intensity of the optical signal are detected by judging the direction and intensity of the leakage. It can directly detect 0.25mm bare optical fiber, 0.9mm, 2.0mm, 3.0mm indoor fiber cable without damaging the cable or interrupting continuous communication.
VFL the red light source is 2mW, which is used to find fault points of 5km link.
OPM with 8 calibrated wavelengths, used to measure the fiber under test.
Low battery monitoring: when the battery is low, a yellow or red prompt will be sent to remind the user to replace the battery to avoid interruption of use.
- The direction and frequency of light can be identified without cutting off the optical fiber.
- The "push to check" operation mode is adopted to make the operation simple and convenient.
- No need to replace the adapter for optical fiber cables.
- It can identify three common signal frequencies: 2kHz/1kHz/270Hz.
- The approximate optical power value of the measured optical fiber can be displayed.

The certificate shows that a component/subsystem can be used in a specific application according to a requirement class (RC) or a integrity level (SIL). The system integrator and end user must always be aware of how to use certified components/subsystems in safety-related function, respectively a safety instrumented system. Because of the many different possibilities and how to configure a safety system, the end user must get the related information from the manufacturer of the certified component/subsystem.



The CE marking is a mandatory European marking for certain product groups to indicate conformity with the essential health and safety requirements set out in European. To permit the use of a CE mark on a product, proof that the item meets the relevant requirements must be documented.
