MediaTek has confirmed the availability of the new 800 GbE MT3729 product family (Dual 400 GbE) PHYs MACsec, which uses 56G PAM4 SerDes technology and comes with four different modes of operation.

The retimer mode , with signal application technology, extends the SerDes connection distance and edge transmission for a more accurate time stamp. forward / reverse gearbox mode offers support for bit rate translation between 56G and 28G links, allowing next-generation switches to connect to existing infrastructure. The MUX / DeMUX mode respects network redundancy needs. And MACsec mode , with IEEE 802.1AE MACsec support, supports secure communications with AES-128 or AES-256 encryption from 1 to 400 GbE per port.

These products have been designed for data centers and 5G infrastructure applications , with high transmission speed and ultra low power. They can be used in line cards or switch structures for multi-terabyte servers, switches and routers.

MediaTek will thus equip service providers and network equipment, keeping in mind that the demand for the data center for networks of 400 GbE and higher will grow over the months.
