Who Are Our Potential Customers?

Every optical fiber preform begins inside a deposition torch. Whether the process is Outside Vapor Deposition (OVD), Vapor Axial Deposition (VAD), or Modified Chemical Vapor Deposition (MCVD), the burner assembly sits at the heart of the reaction zone, delivering precisely balanced gas flows through concentric channels and micro-hole nozzle faces.Every optical fiber preform begins inside a deposition torch. Whether the process is Outside Vapor Deposition (OVD), Vapor Axial Deposition (VAD), or Modified Chemical Vapor Deposition (MCVD), the burner assembly sits at the heart of the reaction zone, delivering precisely balanced gas flows through concentric channels and micro-hole nozzle faces.

These burner assemblies are high-wear consumables. They operate under extreme thermal cycling while being exposed to corrosive halides such as silicon tetrachloride (SiCl₄) and germanium tetrachloride (GeCl₄). Nozzle faces erode, gas distribution plates pit, and micro-holes crust with silica. That is why fiber optic preform manufacturers, and the vertically integrated fiber manufacturers around them, buy burner components continuously rather than once.

So, who are our potential customers? The short answer is any company that manufactures optical fiber preforms or operates deposition equipment. In practice, the market splits into three clear groups.

1. Fiber Optic Preform Manufacturers (Primary Buyers)

Preform makers are the direct users of OVD, VAD, and MCVD deposition torches. Their maintenance teams consume nozzle heads, gas distribution plates, torch tips, and complete burner assemblies on a recurring basis. For these customers, the two most important things are drop-in compatibility and short lead times, because a failed burner can stop an entire multi-hour deposition run.

2. Vertically Integrated Fiber and Cable Manufacturers

Many of the world’s largest fiber optic and cable manufacturers produce their own preforms in-house as part of a full-chain strategy: preform, fiber, and cable. These companies operate large fleets of deposition lathes and need a reliable, field-validated supply of burner consumables across multiple production sites.

3. Specialty Fiber Producers and New Capacity Builders

Specialty fiber producers frequently use MCVD or modified OVD processes to make polarization-maintaining fiber, sensing fiber, and other high-value products. In parallel, a growing number of manufacturers are building new preform capacity, especially in China and India. New production lines mean new torch inventory, replacement-part contracts, and custom component requirements from day one.

Our Target Customers in China

China is the largest optical fiber production base in the world, and its preform industry is concentrated among a group of large manufacturers plus a fast-growing tier of new and specialty producers. The companies below are at the center of this ecosystem.

1. Yangtze Optical Fibre and Cable (YOFC) – global preform and fiber leader with PCVD, OVD, and VAD capabilities
2. Hengtong Group – full-chain fiber and cable manufacturer
3. ZTT – vertically integrated producer of preforms, fiber, and cable
4. FiberHome Technologies – major OVD preform manufacturer
5. Futong Group – integrated preform-to-cable supplier
6. Yongding – optical and electrical cable manufacturer
7. Tongding Interconnection – full-chain optical communications supplier
8. Shenzhen SDG Information – fiber manufacturer expanding into preform production
9. Zhongli Group – OVD/ACD preform producer with expansion projects
10. Hong’an Group – preform and fiber manufacturer
11. YOEC – Wuhan specialty fiber maker using MCVD/PCVD processes
12. Hangzhou Cable – building a major new preform and quartz production facility
13. Fasten Group – preform, fiber, and optical sensor manufacturer

Most of the aforementioned are already our customers, and our products have been validated by them.

How We Serve These Customers

We help preform and fiber manufacturers keep their deposition lines running with two complementary offerings:

– Standard stock models. Four OVD burner assembly models are held in inventory and ready to ship worldwide within 24 to 48 hours. They are engineered as 100% drop-in replacements, matching original physical dimensions, thread sizes, and gas port configurations with no MFC or hardware recalibration required.
– Custom OEM/ODM fabrication. When a customer uses a proprietary torch design, or needs modified port sizes, mounting threads, or channel layouts, we machine components to their exact technical drawings under strict NDA protection.

Every component is produced on precision CNC turn-mill centers to single-digit micron tolerances, with specialized deburring and surface treatment to resist chemical pitting and extend service life in high-temperature deposition environments.

If your facility manufactures optical fiber preforms, or you are building new deposition capacity, we would like to talk. Browse our in-stock burner components or contact our engineering team with your drawings for a custom review.
