Huge growth of data flow brings in great bandwidth pressure to transmission network, so the operators become more urgent to build 100Gbps OTN networks. Also, due to the technical development trend, after point-to-point WDM and OTN, the mainstream operators in the world raised more requirements for WDM technology, e.g. IP WDM technology, intelligent demand and eco-friendly requirement. So the long-distance backbone OTN device should be capable of 100G transport and the integration of the OTN, control plane, optical layer wavelength-class cross-connection and L2 switching technologies.
As a large-capacity and ultra-long distance intelligent backbone OTN device, the ZXWM M920 uses the advanced transport and integrated technologies to give support to IP transport and OTN standard. With the support of uploading GMPLS/WASON control plane, it is now extensively used in global backbone projects, local switching fabric and all sorts of private networks.
