Investigation of Dispersion Compensation in 2.5 Gbit/s OOK Label and 40 Gbit/s RZ-DPSK Payload Optical Label Switching System Based on Optical Carrier Suppression and Separation
Three dispersion compensation schemes of an optical label switching transmission system were investigated,which employs 40 Gbit/s return zero differential phase-shift keying(RZ-DPSK) payload labeled with 2.5 Gbit/s on-off keying(OOK) signal based on the optical carrier suppression and separation(OCSS) technique.In the system,proposed are the receiver sensitivity of payload and label,achieving-32.4 dBm and-38.5 dBm,respectively.Using the optimal dispersion compensation scheme,after transmitted over 160 km and 320 km SMF respectively,the label can be recovered without power penalty,while the payload can be recovered with less than 2 dB and 5 dB penalty,respectively.
