Marvell Global First 400gbe Ethernet Chip

Marvell (full Electronics) today announced the launch of the latest single chip Ethernet transceiver program "Alaska 88X7120", the world's first support to the 400GbE, that is, 400000 trillion Ethernet. According to the data of IDC, 100GbE has become the default option of the super large data center, and the server side is also moving towards 25GbE and 50GbE.
Marvell 88X7120 Mina is thinking of the super large scale data center market, using 50G PAM4 (4 level pulse amplitude modulation) signals, supporting 16 50/25/10/1GbE ports, or 4 200GbE ports, or 2 400GbE ports, and all duplex transmission, which can meet the processing and I/O bandwidth of artificial intelligence, machine learning and other emerging applications. The super high demand.
It is also the first PHY physical layer scheme that is fully compatible with the IEE 802.3cd standard, which defines the 50GbE port type based on PAM4, and optimizes the QSFP-DD and QSFP ports on the 50/200/400GbE network.
The 88X7120 program has now provided samples to key customers, and the volume of delivery is uncertain.
