Abstract
The results of the research on the technology for manufacturing of large-size preforms by using high-efficiency PCVD process have been described. The performance of the equipment used
the study on high deposition rate at 1 g/min and the preparation of large preforms are also included. The fiber length drawn from each preform has exceeded 20 km
with the minimum loss of 0.36 dB/ km at 1.31 μm and of 0.19 dB/km at 1.55 μm.
