Fiber identifier with integrated VFL 10mW visual fault locator, working wavelength 800-1700nm

Use:
This device offers two functions: Fiber identifier and VFL (Visual Fault Locator).
FIBER IDENTIFIER FUNCTION:
Allows you to identify a fiber without damaging it.
This device will identify the frequency injected into the fiber at its origin.
Compatible with 3mm, 2mm, 900um and 250um fibers.
Supports wavelengths from 800 to 1700nm.
Use the guide compatible with your fiber, then lock the device. The display will then indicate the signal direction and intensity.
When the signal frequency is 270Hz, 1KHz or 2KHz, the corresponding indicator will light up on the display accompanied by a buzzer.
Detector type 1mm InGaAs 2pcs.
VFL FUNCTION:
Allows you to use a red light source to highlight defects in a fiber.
Power from -40dBm to +10dBm.
Red light wavelength 650nm, power 10mW.
Metal structure,
Supplied with carrying case,
Operates with one 9V battery (not supplied).
Weight 230g, dimensions 195x32x27mm.
