Core Functions and Applications

Equipment Self-diagnosis and Diagnosis: Quickly checks the functioning of fiber optic ports on aircraft communication systems, network switches, servers, routers, and other equipment. By simulating a link connection, it helps ground crew and engineers quickly identify equipment faults or external fiber link issues.

Port Performance Testing: Verifies the transmit and receive functionality of optical modules (SFP, SFP+, etc.) and is a critical step in regular maintenance, installation, and commissioning of aviation equipment.

Network Troubleshooting: In complex aviation communication networks, segmented loopback testing allows for efficient isolation and localization of faults, significantly reducing maintenance time and ensuring flight punctuality. System Burn-in and Debugging: During system integration and extended operational testing, this feature provides stable loopback connections for optical ports, ensuring continuity and reliability during the testing process.
