Marvell today announced the expansion of its industry-leading 5 nm data infrastructure platform with the launch of the industry’s first 5 nm 50G PAM4 device for the carrier market, the Prestera DX 7321 Ethernet switch. The new switch builds on the success of the Prestera carrier-optimized portfolio and is ideal for 5G fronthaul and edge connectivity. In concert with this, Marvell’s 5 nm OCTEON 10 DPU family, incorporating industry-leading hardware accelerators, is now sampling. By utilizing the industry’s leading advanced process geometry, the Marvell Prestera switch and OCTEON DPU deliver 50% lower power than existing offerings, enabling new infrastructure solutions for next-generation carrier edge networks and RAN deployment models.
With the addition of the 5 nm Prestera device, the expanded carrier-optimized switch portfolio now comprises four cutting-edge Ethernet switches that scale port speeds from 1 Gbps to 400 Gbps with aggregate bandwidths ranging from 200 Gbps to 1.6 Tbps. The newest offering enhances Marvell’s 5G solutions for Open RAN, vRAN and traditional RAN architectures, with Class D precision time protocol (PTP), which provides more timing headroom to enable larger cell coverage radius. The switch device incorporates integrated MACsec security and advanced telemetry to facilitate network visibility and automation.
