Main Uses of Fiber Optic Coating Machine

1. Repairing Fiber Optic Coatings
   This is the most core application. When the outer protective coating of an optical fiber becomes peeled, cracked, or aged due to bending, squeezing, abrasion, or other causes during use, installation, or maintenance, a fiber recoater can repair it by reapplying a robust protective layer.

2. Protecting Fiber Splices and Fusion Points
   During fiber splicing, connector assembly, and similar operations, the coating at both ends of the fiber must be stripped off to enable fusion. After fusion, these bare glass sections are very fragile and prone to breakage. Using a fiber recoater to apply a new coating on these critical areas greatly enhances their mechanical strength and tensile performance.

3. Enhancing Mechanical Strength of Optical Fibers
   The newly applied protective layer effectively shields the internal glass fiber, allowing it to withstand greater tension and bending, thereby preventing damage from external forces during subsequent cabling and use.

4. Improving Environmental Tolerance
   The coating can isolate the fiber from moisture, dust, chemicals, and other external environmental factors, preventing the formation and propagation of micro-cracks on the fiber surface. This ensures long-term stable operation of the fiber in various complex environments.

5. Extending Fiber Service Life
   By repairing damage and enhancing protection, a fiber recoater can effectively prevent performance degradation and breakage caused by physical damage or environmental erosion, thereby significantly extending the service life of fiber optic networks.

Main Application Fields & Specific Operation Examples

1.Enterprise Networks
Used for fiber cabling and maintenance in large campuses and data centers.

Specific operation example: In high-density cabling environments within a data center, administrators may accidentally step on or overbend patch cords when organizing or replacing equipment, causing the outer jacket to break. To avoid scrapping an expensive patch cord, technicians use a fiber recoater to perform a “minimally invasive repair” on the damaged spot. They remove the damaged patch cord and, in a lab or on-site, use a high-precision recoater to reinforce the exposed glass fiber, restoring its original tensile strength and flexibility, thus quickly re-establishing high-speed connections between servers or switches.

2.CATV Networks
Used for maintenance of cable television signal transmission networks.

Specific operation example: During maintenance of outdoor aerial cables, due to prolonged sun exposure, rain, and wind-induced swaying, the fiber coating inside splice closures may become aged and brittle. When line expansion or fault diagnosis requires re-splicing fibers, technicians find that the bare fiber after stripping the old coating breaks easily. At this point, they use a fiber recoater to reinforce both sides of the fusion splice. Especially for outdoor scenarios requiring high UV resistance, they select special weather-resistant resin to ensure the splice point operates stably for a long time under harsh weather conditions, preventing signal interruption.

3.Telecom Operators
Used in the construction and maintenance of backbone networks, metro networks, and access networks (e.g., FTTH).

Specific operation example: During FTTH (Fiber to the Home) installation, when indoor cabling requires sharp bends around corners or passing through narrow conduits, the fiber coating is easily abraded or broken. Maintenance personnel use a portable fiber recoater to locally repair the worn area. The specific steps are: first clean the fiber surface, then place the fiber into the recoater’s mold, inject matching UV-curable resin, and start the machine for UV curing. Within minutes, the fiber’s complete protective layer is restored, ensuring uninterrupted signal transmission and durable cabling.

4.Research & Special Applications
Used in laboratory environments or industrial scenarios with special fiber requirements.

Specific operation example: When fabricating specialty fiber optic sensors (e.g., for measuring high temperature, high pressure, or strain), researchers often need to apply precise coatings on specific fiber regions (such as grating writing zones). For example, in stress testing of aerospace materials, researchers need to embed optical fibers inside the material. To ensure the fiber can sense stress without being worn by the material, they use a micro fiber recoater to apply a nanoscale‑thickness precision coating on the specific sensing region, achieving both fiber protection and unaffected sensing sensitivity.
