The effect of the degree of primary protective coating polymerization on the optical fiber mechanical characteristics
It was shown that the degree of polymerization of the acrylic primary coating affects its hygroscopic property, which in its turn influences the characteristics measured after the exposure at elevated temperature and humidity.
Key words:
optical fiber; primary coating; UV-curing; stress corrosion resistance.

Mechanical calculation of drop cables
The article deals with the FTTH (Fiber To The Home) architecture of a subscriber access network based on the PON (passive optical network) technology. The ОСЦLS-HF drop cable construction with the central polybutylene terephthalate tube filled with hydrophobic gel is presented.
The cable is designed for both outdoor installations along power transmission lines, on contact line masts and electrified railway automatic block systems, and installation inside buildings. A mechanical calculation of the ОСЦLS-HF-1А1 (0.9)-1,2 drop cable construction was performed and mechanical tests of the cable using the РРК-ЕК2 type tensile and crushing setup were carried out. In the course of testing the dependences of the signal attenuation increment in the OF on the tensile and crushing stress values were obtained.
Key words:
optical cable (OC); central optical module; optical fiber (OF); drop cable; FTTH (Fiber To The Home); PON (passive optical network); optical splitters; tensile and crushing stress; mechanical calculation».
