OPTICAL FIBER CABLES AND MODULES WITH MODAL DISPERSON COMPENSATION |
| 摘要 |
An optical fiber cable for bi-directional communication of optical signals is disclosed. The optical fiber cable has a primary multimode optical fiber with an alpha value of a and is concatenated to a compensating fiber with an alpha value α, wherein 1.2≦(α′−α)≦−0.1. The optical fiber cable has a reach between 50 m and 800 m. Modules that employ a plurality of concatenated primary and compensating optical fibers are also disclosed. A bi-directional optical fiber communications system that operates at two different wavelengths is also disclosed. |

1. An optical fiber cable for bi-directional communication of optical signals, comprising:
a primary multimode optical fiber having first and second ends separated by a length L1, an alpha parameter α of about 2.1 and a peak wavelength λp in the range from 820 nm to 880 nm, and a first modal bandwidth BW40 of 4 GHz·km or greater; a compensating multimode optical fiber having first and second ends separated by a length L2<L1 and that is optically coupled to the primary multimode optical fiber at the respective second ends, wherein the compensating multimode optical fiber has an alpha parameter α′<α, and wherein −1.2 (α′−α)≦−0.1; a first optical fiber connector operably arranged at the first end of the primary multimode optical fiber; a second optical fiber connector operably arranged at the first end of the compensating multimode optical fiber; and wherein the optical fiber cable has a reach 50 m<LR<800 m. |
