NK411 Optical Fiber Identifier
NK411 optical fiber identifier uses macro bending for nondestructive live-line testing, finding signal direction and approximate power on single mode and multimode fiber.
Description
Overview
The NK411 optical fiber identifier uses macro bending technology to carry out a nondestructive test on the line; signal direction and approximate power can be detected at any position of SM/MM fibers, avoiding line interruption caused by misoperation.
When the optical fiber is bent the weak optical signal is exposed, and the direction and intensity of the leakage tell the direction and intensity of the optical signal. No damage is done to the optical fiber and communication is not interrupted; 0.25mm bare optical fiber, 0.9mm tight sleeve optical fiber and 3mm jumper can be detected directly, and the recognizer can be equipped with a 10mW VFL to find the fault point of a 10km line (laboratory value).
NK411 Key Features
- No need to cut off the optical fiber, the direction and frequency can be identified effectively
- With the one touch operation mode, the operation is simple and convenient
- Can test the optical power of the measured optical fiber
- Identify three common signals, 2kHz/1kHz/270Hz, with a beep prompt during recognition
- LED indicator is simple and clear, using a dry battery with low power consumption
- High transmittance VFL easily penetrates long-distance optical fiber to find the fault point
