1. 서론
The KOMSHINE KPN-35 is a compact and precise Live PON Optical Power Meter designed for testing Passive Optical Networks (PON). It is capable of simultaneously measuring and displaying optical power levels at three key wavelengths: 1310nm (for ONT upstream), 1490nm (for OLT downstream), and 1550nm (for video signals). This device is essential for installation, maintenance, and troubleshooting of EPON, GPON, and APON networks, providing clear pass/warning/fail indications based on user-defined thresholds.
2. 안전 정보
Please read and understand all safety instructions before operating the KOMSHINE KPN-35. Failure to follow these instructions may result in injury or damage to the device.
- 눈 안전: Never look directly into the optical output port of the device or any fiber optic cable connected to it. Invisible laser radiation can cause severe eye damage. Always use appropriate eye protection when working with fiber optics.

4.1 풀기 및 검사
Carefully unpack the KOMSHINE KPN-35 and inspect it for any signs of damage. Ensure all components are present. The standard package includes the KPN-35 unit and a user manual. Please note that batteries are not included and must be purchased separately.
4.2 배터리 설치
The KPN-35 operates on batteries. Locate the battery compartment on the device, typically on the rear. Open the compartment cover, insert the required batteries (refer to the device label for battery type and polarity), and securely close the cover.
4.3 Attaching the Protective Jacket
The KPN-35 comes with a rubber armor protection and an anti-slip silicone jacket. Carefully fit the silicone jacket around the device to provide enhanced durability and protection against drops and impacts.

5.4 Setting Thresholds
The KPN-35 provides five sets of pre-defined thresholds. Use the TH button to cycle through these threshold sets. The active threshold set number will be indicated on the display. For custom threshold settings, connect the device to a computer and use the provided management software.
5.5 결과 해석
- 통과하다: Indicates the measured power level is within the acceptable range defined by the current threshold.
- 경고: Indicates the measured power level is close to the acceptable limit, suggesting potential issues or degradation.
- 실패하다: Indicates the measured power level is outside the acceptable range, requiring immediate attention or troubleshooting.
5.6 데이터 저장
The device has large-capacity data storage. Press the OK button to save the current measurement data. Refer to the full manual or management software for instructions on retrieving and analyzing stored data.
6. 유지관리
6.1 광 포트 청소
Regularly clean the optical input port of the KPN-35 to ensure accurate measurements. Use a specialized fiber optic cleaning tool or lint-free wipes with isopropyl alcohol. Always power off the device before cleaning.
6.2 배터리 교체
When the battery indicator shows low power, replace the batteries promptly to avoid interruption of operation. Ensure correct battery type and polarity during replacement.
6.3 보관
When not in use, store the KPN-35 in a clean, dry environment, away from direct sunlight and extreme temperatures. Always replace the dust caps on the optical ports to prevent contamination.
7. 문제 해결
- 기기의 전원이 켜지지 않습니다: Check battery installation and ensure batteries have sufficient charge. Replace batteries if necessary.
- 부정확한 판독값: Ensure the optical port and fiber connector are clean. Dirty connectors are a common cause of inaccurate measurements. Verify the fiber type and wavelength settings are appropriate for the test.
- Screen difficult to read in daylight: While the device has an LED backlight, direct sunlight can still affect visibility. Try to operate in shaded areas or adjust your view잉 각도.
- Only one wavelength shows readings: Ensure the fiber connection is stable and clean. If the issue persists, it may indicate a fault with the device or the fiber being tested. Contact support if the problem continues across multiple tests and fibers.
- 기기가 멈추거나 오작동합니다: Try powering off the device and restarting it. If the issue persists, remove and reinsert batteries.
