Compensation of polarization mode dispersion by in-line synchronous modulation

It reveals the principle of compensation PMD by nonlinearly coupled equation with in line synchronous modulation.The compensation of PMD by in line synchronous modulation at 40Gbit/s is computed.The maximum transmission distance is increased three times and the property of transmission system is improved by in line synchronous modulation.The PMD is compensated effectively by in line synchronous modulation.
