JW3116 Handheld Fiber Optical Light Source User Manual

1. Introduction

The Joinwit JW3116 Handheld Fiber Optical Light Source is a newly designed fiber optic tester engineered for fiber network installation, engineering acceptance, and maintenance. When used in conjunction with a compatible handheld optical power meter (such as the JW3216), it provides a quick and accurate testing solution for both Single-Mode (SM) and Multi-Mode (MM) fibers. The JW3116 supports 1 to 4 wavelengths, and its output power is adjustable to meet various testing requirements. This device is designed for ease of use, featuring a good appearance, comfortable handling, and user-friendly controls.

Figure 5: JW3116 Control Panel

1. Power On/Off: Press the red power button (POWER) to turn the device on or off.
2. Wavelength Selection: Press the wavelength button (λ) to cycle through available wavelengths (850nm, 1300nm, 1310nm, 1550nm).
3. Modulation Selection: Press the modulation button (CW/Hz) briefly to select between CW, 270Hz, 330Hz, 1kHz, and 2kHz modulation modes.
4. Wave ID Mode: Press and hold the modulation button (CW/Hz) for an extended period to activate Wave ID mode (for use with compatible power meters).
5. Backlight Control: Press the backlight button (LDR) to control the display backlight intensity.
6. Output Power Adjustment: Use the up arrow (▲) to increase output power and the down arrow (▼) to decrease output power.

6. Maintenance

• Cleaning Fiber End-Faces: Regularly clean the fiber end-faces of both the device ports and your fiber cables using the provided cotton swabs or other approved fiber cleaning tools. Contaminated end-faces can lead to inaccurate measurements and damage.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display to ensure continuous and accurate operation.
• Storage: Store the device within the specified storage temperature range (-25°C to +70°C) and in its soft carrying case to protect it from dust, moisture, and physical damage.
• General Care: Avoid exposing the device to extreme temperatures, direct sunlight, or harsh chemicals. Do not attempt to disassemble the unit, as this may void the warranty.

7. Troubleshooting

• Device Does Not Power On:
  • Check if the batteries are correctly installed and have sufficient charge.
  • If using the AC adapter, ensure it is properly connected to both the device and a working power outlet.
• Inaccurate Readings:
  • Ensure all fiber connections are clean and free of dust or debris. Clean fiber end-faces if necessary.
  • Verify that the correct wavelength is selected on the device for the fiber being tested.
  • Check if the fiber cable itself is damaged.
• No Light Output:
  • Confirm the device is powered on and the selected wavelength is active.
  • Ensure the fiber cable is securely connected to the output port.
  • Check the output power setting; it might be set to a very low value.
• Display Issues:
  • If the backlight is too dim or bright, adjust it using the backlight control button.
  • If the display is blank or frozen, try turning the device off and on again.

8. User Tips

No specific user tips from reviews or Q&A were available for this product at this time. However, general best practices for optical equipment include:

• Always keep fiber connectors clean to prevent signal loss and damage.
• Use the appropriate wavelength for the fiber type and application (e.g., 850/1300nm for multimode, 1310/1550nm for singlemode).
• When pairing with a power meter, ensure both devices are calibrated and set to the same wavelength for accurate loss measurements.

9. Warranty and Support

This device is covered by a manufacturer's warranty. Please note that the warranty may be void if the warranty seal on the device is damaged. For technical support or warranty claims, please refer to the contact information provided in your product packaging or contact your vendor.
