6. Operating Instructions

6.1 QX55-P OTDR Operation

The QX55-P OTDR allows for precise measurement of fiber optic links. Follow these steps for a typical test:

1. Connect Fiber: Connect the fiber under test to the OTDR's optical port. Ensure connectors are clean.
2. Select OTDR Function: From the main menu, navigate to and select the OTDR testing function.
3. Configure Settings: Adjust parameters such as wavelength (e.g., 1310nm, 1550nm, 1625nm), test range, pulse width, and test time (e.g., 15 seconds for average mode). The device supports automatic measurement mode.
4. Start Test: Initiate the test. The OTDR will display the trace and an event table.
5. Analyze Results: Review the trace for events like splices, connectors, and fiber breaks. The event table provides detailed information on distance, loss, and reflectance for each event. Utilize the Link Map function for a simplified graphical view and Pass/Fail judgment.

6.2 FX39 Fusion Splicer Operation

The FX39 is designed for precise and reliable fiber fusion splicing. Follow these general steps:

1. Fiber Preparation: Strip the fiber coating to the required length, clean the bare fiber with alcohol wipes, and cleave the fiber using the FC-30 cleaver to achieve a clean, perpendicular end-face.
2. Place Fiber: Carefully place the prepared optical fibers into the splicing slots of the FX39. The splicer supports various fiber types including FTTH drop cable, bare fiber, 0.9mm fiber cable, and 3.0mm jump cable.
3. Close Dust Cover: Close the dust cover. The splicer will automatically begin the alignment and splicing process.
4. Splicing: The FX39 will perform core alignment and then arc fusion, typically completing in 6 seconds. The display will show the estimated splice loss.
5. Heat Shrink: Move the heat shrink tube over the spliced joint and place it in the heating oven. The oven will heat the tube, protecting the splice, typically in 16 seconds.
6. Cool Down: Remove the spliced fiber and allow it to cool down before handling.

6.3 FC-30 Fiber Cleaver Operation

The FC-30 fiber cleaver is used to create a precise, flat, and perpendicular end-face on optical fibers, which is crucial for successful fusion splicing. It features a tungsten steel blade for durability and an auto-return mechanism for smooth cutting. The all-in-one fiber holder supports various fiber types.

1. Prepare Fiber: Strip the fiber coating to the required length.
2. Place Fiber: Open the cleaver's top clamp and place the bare fiber in the appropriate groove of the all-in-one fiber holder. Ensure the fiber is positioned correctly according to the measurement scale.
3. Close Clamp: Close the top clamp to secure the fiber.
4. Cleave: Push the cleaver blade mechanism across the fiber. The auto-return blade ensures a clean cut.
5. Remove Fiber: Open the clamp and carefully remove the cleaved fiber.

6.4 KPM-35 Power Meter & KLS-35 Light Source Operation

These devices are used together to measure optical loss in fiber optic cables.

1. Connect KLS-35: Connect one end of a known good fiber patch cord to the KLS-35 Optical Light Source.
2. Connect KPM-35: Connect the other end of the patch cord to the KPM-35 Optical Power Meter.
3. Set Wavelength: Ensure both devices are set to the same operating wavelength (e.g., 1310nm or 1550nm).
4. Reference Measurement: Take a reference power measurement with the patch cord directly connected. This establishes a baseline.
5. Test Cable: Insert the fiber cable under test between the KLS-35 and KPM-35 (using additional patch cords if necessary).
6. Measure Loss: Read the power level on the KPM-35. The difference between the reference power and the measured power is the optical loss of the cable under test.

7. Maintenance

Regular maintenance ensures the longevity and accuracy of your KOMSHINE equipment.

• Cleaning Optical Ports: Always keep optical connectors and ports clean. Use lint-free wipes and optical-grade alcohol. Contamination is a primary cause of measurement errors and poor splice quality.
• FX39 Electrode Cleaning/Replacement: Regularly inspect the splicer electrodes. Clean them as needed with a cotton swab and alcohol. Replace electrodes after approximately 5000 splices or if splice quality degrades significantly.
• Screen Cleaning: Clean the LCD screens with a soft, dry cloth. Avoid abrasive cleaners.
• Battery Care: Store batteries in a cool, dry place. If storing for extended periods, ensure they are partially charged (around 50%). Avoid fully discharging or overcharging.
• Calibration: Periodically calibrate the OTDR and power meter according to manufacturer recommendations or industry standards to maintain accuracy. The QX55-P and KPM-35 support self-calibration functions.

8. Troubleshooting

This section addresses common issues you might encounter.

• Poor Splice Loss (FX39):
  • Ensure fiber end-faces are perfectly clean and cleaved.
  • Check electrode condition; replace if worn or dirty.
  • Verify fiber type settings match the actual fiber.
• Inaccurate OTDR Measurements (QX55-P):
  • Clean OTDR optical port and launch fiber connectors.
  • Verify correct wavelength and test range settings.
  • Perform self-calibration if available.
• Device Not Powering On:
  • Check battery charge level.
  • Ensure battery is correctly installed.
  • Verify power adapter connection if operating on AC power.
• VFL Not Working:
  • Check if the VFL port is clean.
  • Ensure VFL function is activated in the menu.
