LIGHT PULSE TRANSMISSION DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a light pulse transmission device having remarkably reduced degradation in transmission characteristics by PMD at an optical fiber for transmission in a light pulse transmission system. <P>SOLUTION: The light pulse transmission device consists of a light transmission system generating a light pulse signal; a light transmission path formed by multi-stage-connecting repeating zones consisting of the optical fiber for transmission and a light amplifier repeater; and a light reception system. A plurality of polarization mode dispersion compensation means improving the polarization to extinction ratio of a light signal are disposed at a plurality of repeating zones. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
