MULTIMODE LIGHT TRANSMISSION SYSTEM AND METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To realize simplification of a configuration and a high speed in a multimode light receiving device. <P>SOLUTION: A multimode light receiving device has: mode convergence devices 22<SB POS="POST">1</SB>to 22<SB POS="POST">5</SB>to which coherent modulation signal light transmitted in a multimode fiber 100 is input and which converges a plurality of modes in the transmitted coherent modulation signal light to a basic mode; and coherent optical receivers 23<SB POS="POST">1</SB>to 23<SB POS="POST">5</SB>receiving the coherent modulation signal light converged to the basic mode by the mode convergence devices 22<SB POS="POST">1</SB>to 22<SB POS="POST">5</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
