to produce optical fiber preform needs to be improved.This paper proposed to use organosilicone in the OVD cladding production.It is found that organosilicone such as D4 itself and the preform production process are both environmental friendly.In the new process

2262 t/y hazardous substance and 1942 t/y HCl were reduced

520000 t/y water were saved.The G.652 D optical fiber prepared meets the ITU—T standard.Typical loss value at 1550 nm is 0.182 dB/km.
