The Fibre Lapping/Polishing Machine is a high-precision device specifically designed for end-face processing of semiconductor fibre optic connectors – the core components of fibre optic communication. By performing nanoscale lapping and polishing on the end faces of fibre ceramic ferrules, it ensures ultra-high flatness, smoothness, and specific geometric shapes (such as PC/UPC/APC curved surfaces). It is a key process equipment for achieving low insertion loss and high return loss, as well as ensuring stable and efficient transmission of optical signals.
1. Core Functions: Ensuring Smooth and Efficient Optical Communication Networks
Achieving ultra-low signal loss: The device can process the end face of the fibre optic connector into a perfect mirror surface, minimizing the reflection and scattering of optical signals at the junction, thereby reducing insertion loss to the lowest level and ensuring signal strength.
Enhancing signal transmission quality: By accurately forming and polishing the APC angled curved surface, the reflected light leaks out of the fibre at a specific angle instead of returning to the light source, significantly reducing return loss. This is crucial for the stability and speed of high-speed fibre optic networks (such as GPON and 5G bearer networks).
Guaranteeing long-term connection reliability: A scratch-free and defect-free fibre end face can ensure that the connector maintains stable physical contact even after multiple insertions and extractions, avoiding signal degradation caused by end face damage and extending the service life of components.
2. Equipment Types and Application Scenarios
(1) Manual/Semi-Automatic Single-Fiber Lapping/Polishing Machine
It is suitable for R&D, small-batch production or maintenance scenarios. Operators can clamp each fibre optic connector and control the process one by one, offering high flexibility. It is a common choice in laboratories, fibre optic patch cord factories and on-site construction maintenance.
(2) Automatic Multi-Fiber Lapping/Polishing Machine
Equipped with a multi-station design, it can process multiple fibre optic connectors simultaneously (such as 12-core, 24-core or even entire MPO/MTP connectors) and automatically complete the entire process from pressure application, lapping to cleaning. It greatly improves production efficiency and ensures good consistency, and is specially designed for large-scale production of fibre optic patch cords and pre-terminated products.
3. Key Process Points and Selection Recommendations
Precise pressure and speed control: The lapping of fibre end faces requires multiple processes including rough lapping, fine lapping and polishing. Each process requires precise control of downforce and disc speed. High-quality equipment can provide stable parameter control, which is the basis for obtaining a perfect curved surface and an ultra-smooth surface.
Crucial matching of consumables: Lapping discs of different materials (such as cast iron discs, glass discs, polyurethane pads) and lapping papers/polishing fluids of different particle sizes (from several microns to nanoscale) directly determine the quality of the end face. Consumables must be scientifically selected according to the connector type (such as LC/SC/MPO) and lapping standards (such as UPC/APC).
Pursuing excellent end-face geometric parameters: When selecting equipment, in addition to focusing on the degree of automation, more attention should be paid to its ability to control the geometric parameters of the processed end face, including Radius of Curvature (R), Apex Offset, and Fiber Height. These are the core indicators for evaluating equipment precision and the performance of the final product.
