Frequently Asked Questions

Find answers to common questions about our fiber optic cables, manufacturing processes, and services.

What is the difference between single-mode and multi-mode fiber cables?

Single-mode fiber (SMF) has a smaller core diameter (typically 9μm) and uses a single light mode for transmission, allowing for longer distances and higher bandwidth. It's ideal for long-haul telecommunications and high-speed data transmission.

Multi-mode fiber (MMF) has a larger core (50μm or 62.5μm) and supports multiple light modes. It's suitable for shorter distances (up to 2km) and lower bandwidth applications, commonly used in local area networks (LANs) and data centers.

What types of fiber optic cables do you manufacture?

We manufacture a comprehensive range of fiber optic cables including single-mode, multi-mode, distribution, breakout, ribbon, armored, aerial, and direct burial cables. Our product line covers various fiber counts from 1 to 144 fibers, with different jacket materials suitable for indoor, outdoor, and harsh environment applications.

How do your cables perform in extreme temperature conditions?

Our industrial-grade fiber optic cables are designed to operate reliably in extreme temperatures ranging from -40°C to +85°C (-40°F to +185°F). For specialized applications requiring even broader temperature ranges, we offer enhanced cables that can withstand -55°C to +125°C (-67°F to +257°F). These cables feature specially formulated jackets and reinforcing materials to maintain performance in harsh environments.

What is the typical lifespan of your fiber optic cables?

Our fiber optic cables are designed to have a minimum lifespan of 25 years when installed and maintained properly. However, many installations remain functional for 30-40 years. The actual lifespan depends on environmental factors, installation quality, and operating conditions. We use high-quality materials and rigorous manufacturing processes to ensure long-term reliability.

What are your international shipping options and lead times?

We ship to over 120 countries worldwide through our network of logistics partners including DHL, FedEx, UPS, and specialized freight forwarders for large shipments.

Lead times typically range from:

  • Standard products: 3-5 business days
  • Custom configurations: 7-14 business days
  • Large volume or specialized orders: 2-4 weeks

Exact shipping times depend on destination and customs clearance procedures.

What is your minimum order quantity?

Our standard minimum order quantity (MOQ) is 5000 meters for most standard cable types. For custom or specialized cables, the MOQ may vary depending on the specifications. We understand that some customers may need smaller quantities for testing or prototyping, so please contact our sales team to discuss your specific requirements.

What certifications do your fiber optic cables have?

Our fiber optic cables meet or exceed international standards and hold various certifications including:

  • ISO 9001:2015 Quality Management
  • CE Certification
  • UL Listing
  • RoHS Compliance
  • ITU-T G.652, G.655 Standards
  • Telcordia GR-409

Specific certifications may vary by product. Please contact our sales team for detailed certification documents for your chosen products.

What is your warranty policy?

We stand behind the quality of our products with a comprehensive warranty policy:

  • Standard products: 10-year warranty against manufacturing defects
  • Custom products: 5-year warranty against manufacturing defects
  • Performance guarantee: Cables meet specified optical and mechanical parameters

The warranty covers material and workmanship defects but does not include damage from improper installation, handling, or environmental conditions beyond specified parameters. For complete warranty details, please request our warranty document.
