We have formed a professional technical service team and provided a 7 × 24-hour customer support hotline to ensure a response within 1 hour of receiving a request, with technical personnel arriving on site within 24 hours.
During the warranty period, if the optical cable malfunctions due to product quality issues, we promise to replace it free of charge and bear the corresponding costs; At the same time, we provide free guidance on accessory selection, recommended construction tools, and systematic operation training to help customers improve project operational efficiency. Outside the warranty period, we still provide regular technical follow-up visits (no less than three times a year), on-site inspections, and system health assessments, and establish customer exclusive files to continuously track usage and optimize products and services based on feedback.
