Can CX7 Dual-port 400G reach 800G after bonding? Why can 200G reach 400G after bonding?

CX7 Dual-port 400G can use Octal small form factor pluggable (OSFP) connectors or Quad small form factor pluggable (QSFP) connectors. It can support bonding technology, which combines two 400G ports into one 800G port, increasing bandwidth and redundancy. However, to achieve the effect of reaching 800G after bonding, the following conditions need to be met:
1. Use OSFP connectors and NDR cables, which can provide 400 Gb/s of bandwidth.
2. Use switches that support 800G, such as the Cisco Nexus 9800 Series or Cisco Nexus 9232E.
3. Configure the correct bonding mode and parameters, such as LACP, load balancing, failover, etc.
If you use QSFP connectors or HDR/EDR cables, then the bandwidth after bonding will be limited, because the maximum bandwidth of QSFP connectors and HDR/EDR cables are 200 Gb/s and 100 Gb/s respectively. Therefore, the maximum bandwidth after bonding using QSFP connectors or HDR/EDR cables is 400 Gb/s.
