Description
Overview
The GAOTek Multi-Wavelength Single Laser Light Source is a handheld device which provides a high stability multi-wavelength output from a single laser source. It can provide 1 to 4 wavelength outputs including a 650 nm red source, 1310 nm/1550 nm wavelengths for single-mode fiber, and 850 nm/1300 nm wavelengths for the multi-mode fiber. This device, when combined with an optical power meter, can be used for measuring optical loss on both single-mode and multi-mode fiber cables.
Key Features
- Provides 1~4 wavelengths output and wavelengths can be optional according to customer requirement
- CW, 2 Hz modulation output at 650 nm, and CW, 270 Hz, 1 KHz, 2 KHz modulation output at other wavelengths
- High stability of the output power
- Stable output wavelength
- Large LCD, easy operation
- Backlight LCD display supports night operation
- Alternative 10 minutes Auto-off function conserving battery life
- Compact size which can be carried easily

Keys and Functions
- Wavelengths output ports: FC/PC or other type connectors can be required.
- Liquid Crystal Display: For wavelength display; Modulation indicator.
- “ON/OFF” Key: Press to turn the Handheld Light Source Light On or Off.
- “Wave” key: For wavelength selection
- “Mode” key: Modulation control: CW light output and modulated light output can be selected by pushing “Mode” key. When modulated light output is selected, a dot appears in LCD.
Operation
- Press “ON/OFF” key for about one second to switch on Handheld Light Source, default wavelength is 1310 nm.
- To use Handheld Light Source light source:
- Connection: FC/PC connector.
- Wavelength selection: Press “Wave” key for wavelength selection.
- Modulation: Press the “MODE” key, choose the “CW”, “270 Hz”, “1 KHz” or “2 KHz” light output.
- Switch off: Press “ON/OFF” key to switch Handheld Light Source off.
Maintenance
- If the Handheld Light Source is not used for a long time, the light output port must be protected with the dustproof hat.
- When the Handheld Light Source is used for a period of time, the output port maybe polluted. It results in the output power decreasing. So the connector must be cleaned with alcohol cotton.
- If not using for a long time, please take out the battery.
- Don’t take apart the Handheld Light Source please. If there are any other troubles, please contact with the manufacturer.
- DO NOT look into Handheld Light Source adapters directly when light source is on, laser output does harm to your eyes.
Trouble Shooting
| No. | Problem | Measures |
| 1 | The output light is unstable or decreases rapidly while operation. | Change battery or re-charge battery. |
| 2 | Output power is fluctuating. | After warm-up for 15 minutes, then operate it. |
| 3 | The output port is polluted. | Clean the connector with alcohol smoothly or contact with supplier. |
