FAQ

These mainly include:
① Order quantity and degree of customization;
② Supply of upstream raw materials (such as optical fiber preforms);
③ Current factory capacity;
④ Logistics distance and customs clearance efficiency (for export orders).

Our products have passed ISO 9001 Quality Management System Certification, ISO 45001 Occupational Health and Safety Management System Certification, ISO 14001 Environmental Management System Certification, RoHS (Restricted Substances), CE (EU Market Access), REACH Compliance Mark, and other authoritative certifications.

Of course. We will proactively provide copies of relevant product certification certificates and third-party test reports (such as insertion loss, tensile strength, and other test data) after order confirmation. We can also provide English versions of these documents upon customer request.

• Single-mode fiber (such as G.652D, G.657A1) is suitable for long-distance, high-speed transmission (such as metropolitan area networks, data center interconnection).
• Multimode fiber (such as OM3, OM4) is more suitable for short-distance, high-density scenarios (such as internal cabling in computer rooms), with lower cost and easier construction.

The core count should be selected based on current bandwidth requirements and future expansion plans, with a common range of 2-288 cores. In terms of structure, a tight-buffered structure is preferred for indoor environments, while loose-tube stranded (such as GYTA) or armored (such as GYTS) structures are recommended for outdoor overhead/duct scenarios to improve mechanical protection.

1. LSZH (Low Smoke Halogen-Free): Suitable for densely populated indoor locations (such as data centers, office buildings), producing less smoke and lower toxicity during combustion, meeting fire safety requirements.
2. PE (Polyethylene): Highly weather-resistant, mainly used for outdoor overhead or direct-buried optical cables.
3. PVC (Polyvinyl Chloride): Lower cost, commonly used for indoor non-critical area wiring, but releases toxic fumes when burned.
