Case Study 1 | Ethernet Verification
400G Ethernet MAC/PCS in Four Configurations
Customer
Global Cloud Provider
Max Rate
400G
Team Size
2 to 4 engineers
Duration
1 to 2.5 mo / config
1 Challenge
Verify 400G Ethernet MAC/PCS in four configurations differing in lane count, lane rate and channelization, including four 400G instances sharing one set of 16 SerDes lanes.
2 Approach
Verification of each configuration was run as a focused engagement by a dedicated team of two to four engineers.
3 Outcome
Verification of all four configurations delivered. Three took about 2.5 months each; the shared-lane subsystem took one to two months.
4 Technical Scope
- 400G on 8 lanes at 50/25G, 1 channel
- 400G on 16 lanes at 100/50/25G, 1 channel
- 4 x 400G subsystem on 16 shared lanes
- 400G on 4 lanes at 100/50/25G, 4 channels
- Rates scaling from 400G down to 100G or 50G
