Fiber Condition

G.652 fiber is settled in this project, and the main wavelength is 1550nm.

M6800 Platform Solution

The M6800 series high density 200G DCI transmission platform is recommended based on customer's business requirements. It has 16x100G client side ports and 8x200G line side ports, supporting up to 16x100G, total 1.6Tbps in a single 1U chassis, suitable for short-distance data center interconnection and long-distance service backbone network transmission.

  • The M6800 series is a large capacity stackable 200G WDM transmission platform. It is mainly used in the backbone network, metro, and DCI transmission. It supports large-capacity OTN dispatching capabilities and integrates functions of OADM, 100G/200G transmission, intellegent management etc. M6800 can build end-to-end OTN/WDM backbone transmission solutions for operators to realize large-capacity scheduling and ultra-wideband intelligent transmission.

Design Details

This solution adopts the M6800 series platform to integrate 40CH pluggable Mux Demux and 200G coherent board which achieves maximum 200G*40CH service on a pair of optical fibers, multiplexing 2 client side 100G services to single 200G for service transmission.

Management Advantages

Open northbound interfaces like SNMP, CORBA, XML, FTP and TL1 to
connect other NMS.

Console, Telnet/ssh, SNMP network management with favourable
user interface, easy to operate.

Unified management of cross-domain equipment, network layer and
network element layer.

Efficient service management, monitoring bring great user experience
and lower maintenance cost.
