OPTICAL COMMUNICATIONS SYSTEM INCLUDING A DIRECTIONAL COUPLER |
| 摘要 |
<p>: Low-loss coupling between a local feed connection or node, and a multi-mode optical fiber bus is provided by reflective insertion of a relatively small number of modes into the bus fiber. Essentially all input power available at the node is thus inserted into the bus, while but a small portion of power is extracted from the bus.</p> |
