Application Value Analysis of MYH-2in1G Fiber Polishing Slurry for Optical Communication Manufacturing

Driven by rapid technological advancement across the optical communications industry, global market demand for multi-fiber connectors such as MT and MPO keeps rising steadily. The precision and throughput of fiber end-face polishing directly determine the quality of optical components and the overall profitability of manufacturers. Independently developed by Mingyanhai (Changzhou) Microelectronics Co., Ltd., the MYH-2in1G two-in-one fiber polishing slurry breaks the bottlenecks of conventional polishing technology through process innovation. It integrates fiber shaping and fine polishing into a single material to drastically streamline production workflows, serving as a core technical solution for optical processing factories to replace imported polishing consumables, cut operational costs and boost manufacturing efficiency.

Conventional fiber polishing consists of four sequential core stages: epoxy stripping, rough grinding, fiber shaping and fine polishing. Silicon carbide shaping slurry and dedicated consumables are required for fiber shaping, while separate matched polishing media must be switched for fine finishing. This complicated workflow drives up labor workload and consumable waste. Worse still, frequent slurry changeovers trigger unstable process parameters, impairing end-face polishing precision and creating major bottlenecks for mass production. Built on optimized abrasive formulation, Mingyanhai’s two-in-one polishing slurry unifies fiber shaping and fine polishing procedures, condensing the traditional four-step workflow into three steps and greatly improving process rationality and production speed.

Lab validation data verifies the slurry’s superior performance metrics: fiber protrusion is tightly maintained within 2083.7–2289.1 nm, core recess is controlled between -39.1 nm and -9.2 nm, and the maximum height deviation between adjacent fibers stays below 197.8 nm. All technical indicators fully comply with prevailing industry standards, enabling precise polishing tolerance control. In addition, the slurry features evenly dispersed abrasive grains and a stable suspension system. It balances fast material removal rates with superior fiber end-face surface finish, sustaining a consistent mass production yield above 95%.

The product delivers three core competitive advantages: First, dramatic productivity gains and optimized cost management. Per-tray polishing cycle time is cut by 50% compared with traditional processes, effectively doubling throughput. Fewer parameter calibrations reduce expenditures on labor, consumables and production downtime. Second, consistent and reliable component quality. Formulated with eco-friendly water-based chemistry, the slurry rinses clean without residues and contains zero heavy metals. Its anti-delamination suspension system delivers far longer service life than standard polishing slurries. Third, uniform polishing results batch-wide. It eliminates dimensional deviations induced by repeated slurry replacement, ensuring consistent geometry and surface smoothness for all fiber ends on every polishing tray.

This polishing slurry boasts extensive compatibility. It is engineered for 12-fiber and 24-fiber MT/MPO/MTP multi-fiber connectors, as well as standard single-fiber variants including SC, LC, FC and ST. It works seamlessly with center-pressure, four-corner-pressure and fully automatic polishing machines, with no mechanical retrofits required for existing production lines. Furthermore, Mingyanhai offers custom formulation development and sample testing tailored to unique manufacturing requirements, alongside matched three-step polishing pads. These full-spectrum offerings shorten process debugging cycles, raise polishing pass rates and deliver complete turnkey polishing solutions for manufacturers.

Simple storage and handling procedures are specified for user convenience: Keep containers tightly sealed in a cool, dry location away from direct sunlight and excessive heat. Re-seal promptly after opening and shake thoroughly before every use. The product shelf life is six months.
