The GAOTek Fiber Optical Multimeter provides a wide range of optical power measurements for one to four wavelength laser ranges with stable output. It can provide a single 650 nm visible red light, dual-wavelength 1310 nm and 1550 nm laser output using single-mode fiber, or provide 850 nm/1300 nm/1310 nm/1550 nm four wavelength laser output. This is an ideal test instrument which comes with an automatic shut-down feature, wide range of optical power measurements, and a general interface design. Additionally, both linear (mW) and non-linear (dBm) indices display on the same screen. It is an useful device for maintenance of fiber optic networks.
- Handheld, easy to use device.

Maintenance and Precautions
- Don’t watch the output port with eyes while it is running, the laser will hurt your eyes
- If you are not going to use the tester for long time, cover the dust-proof cap immediately to keep the end clean, don’t expose it in air for long time, otherwise dust may gather polluting the output end.
- After the stabilized light source works for a time, dirt or dust may gather at output end reducing output optical power, if so, user can gently wipe the surface using cotton swab dipped with alcohol, then remove the contaminants with dry cotton swab. If end still look dirty after doing so, please contact us
- For any other fault, please immediately contact our technician, don’t open the cabinet of the device to repair it by yourself, otherwise more serious problems may occur. We will not repair any product that have been disassembled by user himself
|1||Output light is found unsteady||Please recharge the battery|
|2||The terminal of adapter is dirty||Clean it gently with alcohol|
|3||The output optical power is unsteady after start-up||Pre-warm the device for 15 minutes before using it.|
