Classification and characteristics of optical fiber filling paste for cables

Time:2022-03-25 Views:


1. The ideal buffer material for optical cables can protect the optical fibers from micro-bending losses caused by external stress damage;


2, moderate viscosity, strong thixotropy, can be filled at room temperature;


3. Water-swelling and water-blocking type: fast water absorption, high water absorption rate, and good water-blocking performance; thermal expansion and water-blocking type: rapid expansion in case of heat, uniform expansion, neither hard nor brittle;


4. Excellent temperature performance and long-term stability;


5. Good compatibility with optical cable materials, small acid value, oxidation resistance, etc.;


6. Good workmanship and quality stability.
