The optical and electronic racks of the OSN 9800 equipment communicate through master-slave sub-rack cascading, and are connected through the GE1/2 ports on the CTU single board.

Explanation

Option A is correct because in the Huawei OSN 9800 platform, the optical sub-rack and electronic sub-rack are designed to interoperate via a master-slave cascading architecture, where the CTU (Control and Timing Unit) board serves as the communication bridge between racks using its GE1 and GE2 ports. This design allows the control plane to coordinate timing, management, and signaling across physically separate sub-racks as if they were a unified system. Option B is wrong simply because it contradicts the documented hardware architecture - the GE1/2 ports on the CTU are specifically provisioned for this inter-rack cascading function, not for external network connections.

Memory tip: Think "CTU = Cross-rack Traffic Unit" - the GE1/2 ports are the glue that binds optical and electronic racks together in a master-slave chain. If you remember that CTU handles inter-rack coordination via GE ports, this statement will always read as True.
