DDC Port-to-Port  / Rack-to-Rack Interconnect

HiWire SPAN AECs are used in Distributed, Disaggregated Chassis (DDC) applications and for port-to-port or rack-to-rack interconnect in data center routers, and switches in the Spine and Leaf.

In DDC implementations, AECs enable traditionally homogeneous hardware racks coupled with operating systems to be decoupled, enabling architects to mix-and-match configurations for optimal cost, power, and performance requirements. SPAN AECs are an affordable, higher reliability, lower power alternative to Active Optical Cables (AOCs) the connect DDC racks.

The low-power LP SPAN and SPAN AECs are offered with 56G/lane link speeds. Designers looking to redirect power to processing and storage can reduce data transport power by replacing AOCs, which average 50% more power than LP SPAN AECs. 

The PAM4 SPAN AECs are available with QSFP-DD and QSFP56 connectors, inside which are Credo low power, high performance retimers.
