24/7 emergency response is supported in major domestic regions, with remote access diagnostics within 2 hours and engineers arriving on-site within 4 hours. For overseas customers, a professional customs clearance team ensures smooth logistics, guaranteeing critical equipment is restored to operation within 72 hours.

Military-grade products are recommended to undergo full-process maintenance every 6 months, including parameter calibration, airtightness testing, and fiber optic end-face cleaning. Industrial-grade products can have this extended to 12 months, with the specific cycle customized based on the usage scenario.

Our products utilize ceramic encapsulation and thermal management design, and have passed wide temperature verification from -55℃ to 125℃. If performance fluctuations occur, our after-sales team will conduct environmental adaptability testing and provide thermal cycling optimization solutions or replace the product with a military-grade temperature-resistant product.

Common issues include incorrect wiring, power supply voltage mismatch, or overload. We provide a standardized installation manual and video tutorials, and support on-site installation training. If the problem persists, our after-sales team will visit the site within 24 hours to inspect and adjust the configuration.

Our technical team will remotely diagnose circuit interference or parameter deviations and provide customized performance optimization solutions. If necessary, we will dispatch engineers to the site within 4 hours for debugging, ensuring stable transmission is restored within 24 hours.
