Abstract :
A hybrid technology for the preparation of standard and dispersion-modified single-mode (SM) fibers is discussed. Only the most important central region of the fibers is prepared by plasma chemical vapor deposition (PCVD) techniques. The optical cladding is as a high-purity jacket tube using the normal rod-in-tube obtained from low-cost shaping and sintering technologies. Due to in situ plasma etching, no disturbance is caused by the interfaces. Low attenuation is achieved with less than 5% of the fiber volume consisting of PCVD core region. The hybrid technology allows economic mass production of preforms containing more than 300 km of fiber
