Feature

High-quality coating, no deformation at 300℃, and adjustable coating thickness;

Our company adopts a specially designed vertical online thermal curing process, which has a wide adjustable coating thickness range, good concentricity of the optical fiber coating, smooth coating surface, no stress concentration points, and significantly improved screening strength; At the same time, the curing is uniform to reduce glue residue. During our 300℃ high-temperature thermal shock test, it does not bend or deform, and still maintains good bending and tensile strength after long-term high temperature;

High-speed preparation of low-loss optical fiber;

Polyimide is different from the photocuring method of acrylate, and requires a thermal curing process. The curing time of this process is long, which makes the fiber drawing speed much slower than the conventional acrylate drawing speed, and it is easy to increase the loss of the optical fiber in a long drawing process;

Based on the longer fiber travel and specially modulated PI coating in the online continuous thermoplasticization/thermal curing process, our process can achieve excellent coating quality at a higher drawing speed, significantly improve the preparation efficiency of high-temperature resistant optical fiber, and improve the consistency of optical fiber geometric parameters. Based on multi-level and multi-parameter PI material coating, we have achieved a thicker PI coating layer and lower single-mode fiber loss by adjusting the different physical and chemical properties of the inner layer material, middle layer material, and outer layer material;
