Credo published 800G HiWire CLOS AEC

Don Barnetson, vice president of Credo products, said: "Credo believes that 800G is the node where passive DACs are facing a wall-for most customer applications, DACs are too thick and not flexible enough, which will increase the cost and engineering burden of switch manufacturers. Credo‘s newly launched 800G CLOS AEC has similar wire diameter and touch to Cat6 cable, with 100 times higher reliability than AOC, but power consumption is only half of the AOC solution. It is expected to be mass-produced in early 2022.

The CLOS AEC 800G PAM4 cable has two specifications, QSFP-DD800 (Quad Small Form Factor Pluggable Multi-source Protocol Group) and OSFP (Octal Small Form Factor Pluggable). The Credo Retimer function is integrated inside the cable, which can achieve high performance without the need for other external components, which simplifies user design and reduces system cost and power consumption.
