We provide 3 years free standard warranty for all products. If any quality problem occurs during the warranty period, we support free replacement and after-sales maintenance. The Marvell® PAM4 optical DSP portfolio, including Spica™ and Nova™ DSPs, addresses the critical the need for high-bandwidth optical interconnects to power AI infrastructure. For large bulk orders, we can negotiate to provide 5 years extended. Credo's high‑performance, energy‑efficient PAM4 optical DSPs are designed for the demands of hyperscale data centers and AI compute fabrics. They deliver reliable, ultra‑low‑latency performance and strong network resiliency, while Credo's low‑power SerDes architecture provides industry‑leading. The 400GBASE-VR4F OSFP module, MTP/MPO-12 connector, up to 50m over parallel OM4 multi-mode fiber. It is compliant with OSFP MSA, IEEE 802. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parameters. The high bandwidth module supports 400G Ethernet connections over parallel. MaxLinear's highly integrated PAM4 DSPs offer superior link-margin performance and low power to enable 100G, 400G, 800G, and 1. 6T optical interconnects inside the data center.
