5. Setup Instructions
5.1. Battery Installation
- Locate the battery compartment on the back of the KPV-53 device.
- Open the battery compartment cover.
- Insert three (3) AAA 1.5V alkaline batteries, ensuring correct polarity.
- Close the battery compartment cover securely.
5.2. Connecting Fiber Optic Cables
The KPV-53 features a 2.5mm universal interface for the Optical Power Meter and a dedicated port for the Visual Fault Locator. Ensure to use the correct adapter for your fiber type.
- Remove the dust cap from the desired port (OPM or VFL).
- Clean the fiber optic connector end-face thoroughly using appropriate fiber cleaning tools.
- Insert the cleaned fiber optic connector into the device port. For OPM, the standard connector is SC UPC, but adapters for FC, ST, and LC are available (optional).
- Ensure a secure connection.
6. Operating Instructions
6.1. Power On/Off
- To power on the device, press and hold the Power button (
) until the display lights up. - To power off, press and hold the Power button again. The device also features an automatic shutdown function after 5 minutes of inactivity.
6.2. Optical Power Meter (OPM) Function
- Connect the fiber optic cable to the OPM port as described in Section 5.2.
- Press the Wavelength (λ) button to cycle through the available calibrated wavelengths (850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) until the desired wavelength is displayed.
- The current optical power measurement will be shown on the LCD in dBm, dB, or uW.
- Setting Reference (REF) and Unit (dB/dBm): Press the REF/dB button to switch between absolute (dBm) and relative (dB) measurements. To set a reference value for relative measurements, press and hold the REF/dB button.
- Calibration: For calibration, connect the KPV-53 to a light source of the same wavelength. Simultaneously press the REF/dB and VFL keys to enter the adjustment interface. Use the Wavelength (λ) key for downward adjustment and the REF/dB key for upward adjustment. Once the desired calibration is achieved, press the VFL key to save the parameters.
6.3. Visual Fault Locator (VFL) Function
- Connect the fiber optic cable to the VFL port as described in Section 5.2.
- Press the VFL button to activate the red laser.
- Observe the fiber for any light leakage, which indicates a break or fault. The VFL operates in both Continuous Wave (CW) and Modulation modes.
- Press the VFL button again to turn off the laser.

7. Maintenance
7.1. Cleaning
- Always clean fiber optic connector end-faces before connecting them to the KPV-53 to prevent contamination and ensure accurate measurements. Use lint-free wipes and fiber optic cleaning solutions.
- Keep the device's optical ports covered with dust caps when not in use to prevent dust and debris from entering.
- Clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
7.2. Storage
- When not in use, store the KPV-53 in its protective packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
- If storing for an extended period, remove the batteries to prevent leakage.
8. Troubleshooting
- Device does not power on:
- Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Inaccurate OPM readings:
- Ensure the fiber optic connectors are clean. Verify that the correct wavelength is selected on the OPM. If readings are consistently off, consider recalibrating the device as per Section 6.2.
- VFL laser is not visible:
- Confirm that the fiber optic cable is properly connected to the VFL port. Ensure the VFL function is activated by pressing the VFL button. Check for any obstructions in the VFL output port.
9. User Tips
- Always clean fiber optic connectors before use to ensure accurate measurements and prevent damage to the device's optical ports.
- Utilize the appropriate fiber adapter for your specific connector type (SC, FC, ST, LC) to ensure a proper and secure connection.
- Regularly check the battery levels, especially before critical testing, to avoid interruptions during operation.
- When using the VFL, be mindful of the Class 3b laser and avoid direct eye exposure.
