Fiber optic manufacture in china has so many years of adjustment, the domestic high-quality cable price has been one of the world's most, blindly to price to compete must sacrifice product quality, damage to customer benefits as the price, the final result will be both part, some resolution fiber quality method under the surface.

First of all, pay attention to see its ointment. Ointment are fiber paste and cable paste, under normal circumstances should be full of the loose tube fiber paste, cable paste should be each gap filled cable core under pressure. Now the fiber paste filling half or fewer practices, cable paste is just the outside of the cable core with a layer of, some of it is in the middle of two charge is not charging cable. Fiber producers, for example, the fiber optic patch cord supplier think that make fiber products is not well protected, the influence of optical fiber attenuation, transmission performance, poor waterproof performance is not up to the national standards, once the cable accident will cause the entire link Seepage seepage scrap.

Second, pay attention to product protection sleeve. Fiber optic cable sheath should adapt to many different complex climate environment, but also to ensure the long-term (at least 25 years) stability. Fiber optic product on best fiber optic test equipment not only have a certain strength, low thermal deformation, wear, permeability, thermal shrinkage and the coefficient of friction,but also esistance to environmental stress is strong, good processing properties of materials. You use less or sheath material not good although through factory acceptance, but because of quality defects in use after a period of crack, seepage, if using recycled plastics to replace the high quality polyethylene sheath material is more serious.
