As the rapid development of optical fiber communication
the demand on silica based single mode fiber (SMF) is increasing dramatically. The productivity of SMF is restricted by several factors with traditional MCVD process. This paper gives a brief analysis about these factors at first
and then
reviews the new technologies to overcome them
including using synthetic silica tube
various hybrid processes and new heating technologies to substitute for H 2 O 2 flame .Finally
suggestions about the development of optical fiber fabrication in China are presented.
