Fiber Polishing Film: Types, Maintenance, and Selection Guide

Sunmafiber offers a wide variety of Fiber Polishing Film sizes and types to fulfill the performance and polishing needs of all fiber optic connector end faces. These polishing films, which feature microscopic abrasive particles placed onto polyester material, are designed for cable assembly houses, field-installable connectors, and tool kits. They provide the high-precision grinding and finishing processes required to manufacture high-quality optical interfaces.

Polishing Film Types

There are several types of fibre optic polishing films on the market, each with unique properties and applications. Silicon carbide (SiC) film is a strong and long-lasting choice for removing significant amounts of epoxy and glass, as well as for pre-polishing procedures.

Aluminium oxide (Al2O3) film is softer and finer, resulting in smooth and uniform polishing of single and multimode fibres, making it perfect for final polishing steps. Diamond film is a high-end and expensive option for achieving the lowest surface roughness and greatest reflectivity on fibre end faces. It has a long lifespan and is commonly used to polish high-precision connectors such as angled physical contact (APC) connectors. The Fiber Curing Oven is also equally important.

Polishing Film Maintenance

To ensure the best performance and longevity of your fibre optic polishing film, do some basic maintenance, such as cleaning it on a regular basis with a soft brush, lint-free cloth, or compressed air. You can also use isopropyl alcohol to get rid of persistent epoxy residue. It's also crucial to keep the film clean, dry, and cold, away from direct sunshine, heat, and moisture. When the film begins to show indications of wear, tear, or deterioration, such as loss of abrasiveness or smoothness, change in colour or appearance, creation of cracks, holes, or bubbles, or increase in insertion loss or back reflection, it should be replaced. Inspect the film before and after each use, and destroy it if it is no longer functional, to ensure the integrity and dependability of your fiber optic connectors.

Polishing Film Selection

When choosing the best Fiber Polishing Film for your connectors, consider the connector type and specification, such as single-mode or multimode, flat or angled, standard or high-precision. Then, choose the suitable polishing film type based on the connector type and specifications, such as SiC, Al2O3, or diamond. Next, select the appropriate polishing film grade based on the polishing stage and desired surface finish.

Fiber Cable Cutting Machine: Functions, Features, and Types

The Fiber Cable Stripping Machine not only protects the fibre core, but it also significantly improves connection efficiency. Fibre stripping tools and equipment are specifically designed to prepare fibre end faces. It may securely and efficiently remove the optical fiber's outer sheath and buffer layer, exposing the core. This is an important step in fibre end-face preparation because it prepares the fibres for splicing or connecting later on.

What is the function of fibre stripping tools?

• Protect the optical fibre core from damage. The precision stripping design minimises damage to the optical fibre core.
• Increasing the effectiveness of optical fibre link construction: The automated stripping procedure significantly increases work efficiency.
• Ensure the quality of the fibre end faces. A successful stripping effect establishes the groundwork for later fibre processing.
• Convenience for fibre optic network installation and maintenance: The Fiber Cable Cutting Machine is an essential auxiliary instrument for fibre optic connection procedures.

Technical features of optical fibre stripping tools.

Main characteristics of optical fibre stripping tools:

• Stripping blade: With a precision-ground blade, the outer layer of the optical fibre can be safely stripped.
• Fibre positioning mechanism: It can fix and position the optical fibre to ensure that the stripping process remains stable.
• Adjustment mechanism: The stripping depth and length can be modified to fit various optical fibre parameters.
• The waste collecting chute catches the peeling exterior material, keeping the working area clean and neat.
• Electric drive: Some high-end peeling equipment employs electric drives to automate its operation.

Differences between several types of peeling tools:

• The manual stripping tool is simple to use and ideal for small-scale fibre optic connection building.
• Electric stripping tools are highly automated and appropriate for large-scale optical fibre network building.
• Adjustable stripping tool: It can be adjusted to fit different fibre sizes and has a wide range of applications.
• Special stripping tools are created for certain optical fibres, such as tiny optical fibres and metal-coated optical fibres.

Key technical indications for the optical Fiber Cable Stripping Machine:

• Striping accuracy determines the condition of the optical fibre end face after stripping, which influences splicing loss.
• Strip length adjustment range: determines the tool's applicability and ensures compatibility with various connectors.
• Skin blade life determines the tool's service life and maintenance cost.
• Operational convenience has a direct impact on the job efficiency of optical fibre construction people.
