Optical fiber, optical transmission line and dispersion compensating module |
摘要 |
Proposed are a dispersion compensating fiber and an optical transmission system that can, using a short length of the fiber, compensate the chromatic dispersion and the dispersion slope of a non-zero dispersion shifted fiber whose chromatic dispersion is +2 ps€¢nm -1 €¢km -1 to +10 ps€¢nm -1 €¢km -1 and whose dispersion slope is +0.04 ps€¢nm -2 €¢km -1 to +0.12 ps€¢nm -2 €¢km -1 at 1550 nm. In the optical transmission system 1, an optical transmission line 30 that consists of a dispersion-shifted fiber 31 and a dispersion compensation fiber 32 is installed between stations 10 and 20. The dispersion compensating fiber 32 has the chromatic dispersion of -250 ps €¢nm -1 €¢ km -1 ~ -40ps €¢ nm -1 €¢ km -1 and the dispersion slope of 0.015 ps€¢nm -2 €¢km -1 ~ 0.030 ps€¢nm -2 €¢km -1 at 1550 nm. |
