RZ and CSRZ ULH transmission system based on dispersion compensation CBG

Using dispersion compensation CBG, 2500km-10Gbps RZ and CSRZ transmission system on G.652 fiber is successfully demonstrated without electric regenerator and without Raman amplifier. At 2080km and 2560km, power penalty for RZ is about 3dBm and 5dBm (condition: RZ signal, BER=10-12, PRBS=1023-1); And power penalty for CSRZ is about 1dBm and 3dBm. The result indicates it is superior to the system using CSRZ signal under same condition.
