Paper Abstract

This paper describes recent advances in high capacity WDM transmission technologies. The 40 Gbps OTN system-LSI implementation technologies for 40 Gbps WDM transport systems, which accommodate not only 40 Gbps client signals such as STM-256/OC-768, but also STM-64/OC192 and 10 gigabit Ethernet (10 GbE) client signals, and support fully transparent transport are reviewed. A 44.6Gbps RZ-DQPSK WDM transmission experiment utilizing a single chip OTN system-LSI is described. The challenges for over 10 Tbps long haul WDM transmission with the channel rate over 100 Gbps for the WAN (wide area network) transport of 100 gigabit Ethernet (100 GbE) LAN client signals are also reviewed. Feasibility of novel modulation formats and distributed amplification is confirmed by WDM transmission experiments.
