Broadcom Corp. has revealed that its latest 40/50/100 Gigabit Ethernet (GbE) PHY in pluggable QSFP+ optical and DAC modules face increasing uptake. Multiple OEMs and ODMs have adopted the devices for immediate implementation, stated the company.

To meet rising data traffic demands, network operators are looking for cost and performance improvements in the data centre that can leverage legacy cabling. Optimised for 40G quad small form-factor pluggable (QSFP) optics and direct attach copper (DAC) applications, the Broadcom PAM4 devices enable transmission rates of 40/50Gb/s over the existing infrastructure.

"The rapid adoption and support of our PAM4 technology by our leading customers and partners reinforces Broadcom's leadership in wired physical layer devices," said Lorenzo Longo, Broadcom, VP and GM, physical layer products, Broadcom. "Our devices are designed to support higher data throughput over existing low bandwidth channels by transmitting more bits per symbol, significantly reducing cost by eliminating the need for expensive interconnect media."

The Broadcom PAM4 devices support a variety of DAC reaches from multiple suppliers, enables SMF/MMF optics and silicon photonics and features a low-power 28nm CMOS design. In addition, the small 7mm x 7mm package fits within QSFP+ form factor, cable assembly and optics modules.

The BCM82040 and BCM82004 are sampling.
