High Temperature Resistant GPON Equipment Test Report

GPON equipment successfully passed high-temperature testing, maintaining full functionality and structural integrity under extreme conditions.Test Overview

The GPON equipment underwent a temperature cycle test to evaluate its high-temperature resistance. The test involved exposing the equipment to 80°C for 24 hours, followed by -40°C for 24 hours, while the device remained powered on to simulate operational conditions . This approach ensures that both the thermal stress and functional performance are assessed simultaneously.

Test Methodology

• Temperature Cycling: The equipment was placed in a controlled environment chamber, cycling between high and low temperatures to simulate extreme environmental conditions.
• Electrical Strength Test: A sine-wave voltage at 50 Hz or 60 Hz was applied across insulation points, gradually increasing from half to full specified voltage. The overcurrent relay was monitored to ensure it did not trip below 100 mA, and no flashover or breakdown occurred .
• Inspection Criteria: The equipment was evaluated for appearance, functional performance, and electrical integrity after the test. Any damage, malfunction, or deviation from normal operation would have been recorded.

Test Results

• Structural Integrity: No physical damage was observed on the equipment after the temperature cycle test.
• Functional Performance: All functions of the GPON equipment remained normal, including data transmission and network connectivity.
• Electrical Safety: The equipment passed the electrical strength test without flashover, breakdown, or overcurrent issues .
• Traceability: The test was conducted according to national reference standards, ensuring reliability and repeatability of results.
