由于国际互联网的发展对带宽的需求,国际上光缆敷设在1999年比1998年增长了38%(以成缆光纤计),而非零色散位移光纤(NZ—DSF)的用量则增加了159%。这一增长造成了1999年国际市场上光纤的短缺,二光纤的短缺将持续整个20O0年,直至2001年,光纤的供应仍将偏紧。
Due to the demand for bandwidth development due to the development of the Internet, international cable laying increased by 38% (in cabled fiber count) in 1999 compared to 1998, while the use of non-zero dispersion shifted fiber (NZ-DSF) increased by 159%. . This increase caused the shortage of optical fiber in the international market in 1999, and the shortage of the second optical fiber will continue for the entire 2020 years. Until 2001, the supply of optical fiber will remain tight.
