Migrating to 400G brings unprecedented speed, but it also introduces complex testing hurdles. In our latest webinar, Vitex experts discuss how to navigate the shift from NRZ to PAM4 signaling and ensure your network is deployment-ready.
Key Testing Hurdles
- PAM4 Signaling: Unlike traditional NRZ, 400G uses PAM4, which is more sensitive to noise. Testing must focus on tighter eye-diagram margins.
- FEC Performance: Since 400G relies on Forward Error Correction, testing "Pre-FEC" and "Post-FEC" bit error rates is essential to predict real-world stability.
- Interoperability: Ensuring that transceivers from different vendors talk to each other and the switch fabric without signal loss.
Why Testing is Critical
The webinar emphasizes that standard "link-up" tests aren't enough. Validating thermal performance and power consumption under full load is the only way to prevent mid-operation failures in high-density racks.
