Optical glass fibers strength

The telecommunication industry requires optical glass fibers with very high strength (>1 GPa) over very long lengths (>1 km). For example, the True Wave single mode fiber of Lucent Technologies is routinely subjected to a proof stress of 0.7 GPa (see below) while the Weibull modulus is claimed to be 147 (Kummer,... [Pg.265]

Fij . 17. Weibull plots of optical glass fibers subjected to pulse-irradiation and continuous wave treatments. The use ol pulsed exeitner radiation lowered the liber t racture strength by as rniich as a factor of 4 compared to the liber that was subjected to a CW argon-ion laser. The lower fracture strength ol pulse-irradiated liber is a result of the formation of microcracks in the material (after Varelas el al.. 1997). [Pg.23]

The mechanical properties of silicate- based glasses have been extensively studied due to their widespread use as containers, reinforcing fibers, and optical fibers. Consequently, there is a wealth of information on the influence of many variables on the mechanical properties of these glasses. We shall concentrate on (a) composition and temperature effects on modulus and strength and (b) an important method of strength enhancement in glass fibers. [Pg.440]

In optical fiber cables [2], the PP is used to produce the slotted cores which hold the coated glass fibers together. The slotted core is the protective sleeve extruded directly onto the glass fibers. Radiation-cross-linked PP homopolymers are another possibility for this application. The PP plays the role of providing mechanical strength to the optical fiber cables. [Pg.656]
