OptiXtrans DC908 product is usually used in backbone long-distance networks.

TheOptiXtrans DC908is specifically designed fordata center interconnect (DCI)applications, not backbone long-distance networks. Its primary use cases include:

Connecting geographically distributed data centers for cloud services, disaster recovery, and load balancing.

Supporting short-reach, high-capacity links (e.g., metropolitan areas) rather than ultra-long-haul backbone networks.

For long-distance backbone networks, Huawei offers other products like theOptiXtrans E9600 seriesorOSN 9800 series, which are optimized for higher capacities and longer distances.
