HiWire Active Electrical Cables

Credo’s distinctive purple HiWire™ Active Electrical Cables (AECs) are plug-and-play copper interconnect cables designed for affordable, lossless operation at 100G, 200G, 400G, and 800G speeds. AECs come with built-in retimer, gearbox, PCS, and FEC terminations. AECs offer a high-performance alternative to short, thick DACs and high power, high-cost AOCs for data center and telecom applications.

Hyper Scale & Enterprise Data Center

DDCs replace proprietary, high-cost chassis using back panel interconnect with standards-based white box hardware, open-source or 3rd party software and front panel interconnect. AECs take up to 75% less volume than DACs and up to 50% less power than AOCs enabling unprecedented DDC densities.

5G Wireless Service Provider

Of all data center cabling infrastructure, Server (NIC) to Top-of-Rack (TOR) switch links are undergoing the most innovations. AECs enable extended lengths for shared TORs, gearboxing for NRZ-PAM4 links, and advanced functions enabling network-managed redundancy and security.

Introducing HiWire Active Electrical Cables (AEC)

Active Electrical Cables are narrow gauge copper cables with industry standard connectors at each end. Credo has integrated our low power, high performance retimers, gearboxes and FEC circuitry in the connectors to ensure signal integrity at 56G and 112G per Lane over reach ranging from 0.5m to 7m. The SerDes devices not only ensure signal integrity retiming, and speed shifting, but they enable throughput with cables that are lighter weight, less volume, and more reliable than other solutions.

There are six major attributes that define AECs.

Low Power
Light Weight
Bend Radius
Bend Shifting/Retiming
Long Life
Standards Compliance

Collectively these enable AECs to replace DACs with up to 75% less weight and volume, tighter bend radius, and longer reach at 800G. AECs also replace Active Optical Cables at up to half the power with reliability far exceed AOCs and total cost of ownership savings of nearly 65% compared to optical solutions.

HiWire Consortium

Over 50 companies worldwide and growing have come together in the HiWire Consortium to drive specifications and standards to accelerate the deployment AECs. To learn more about the organization and inquire about joining, please visit hiwire.org.
