A novel chromatic dispersion monitoring method for 1 024 QAM fiber-optic system based on asynchronous amplitude sampling

A new chromatic dispersion（CD） monitoring method is proposed, and the CD monitoring is achieved on the whole range of 0-600 ps/nm. A dual-polarization（DP）-1 024 quadrature amplitude modulation（QAM） 400 Gbit/s CD monitoring system is built using OptiS ystem14.0 software. With different optical signal...

Description
Summary:A new chromatic dispersion（CD） monitoring method is proposed, and the CD monitoring is achieved on the whole range of 0-600 ps/nm. A dual-polarization（DP）-1 024 quadrature amplitude modulation（QAM） 400 Gbit/s CD monitoring system is built using OptiS ystem14.0 software. With different optical signal to noise ratio（OSNR） values, different filter bandwidths or different duty cycles, the simulations are carried out. The simulation results show that this new CD monitoring method can be less affected by noise and has a high tolerance for different filter bandwidths. At the same time, this method can do effective CD monitoring on the signal with duty cycle greater than 80%. A high sensitivity in 0-200 ps/nm can be achieved using this CD monitoring method. The technique supports a wide range of data traffic and enhances operation flexibility of optical networks.
