400 GB QSFP-DD LP AEC Datasheet

Take advantage of Approved high performance Active Electrical Cables

Approved’s Active Electrical Cables (AECs) provide affordable 400G QSFP-DD and OSFP interconnections for data center and ISP applications. AECs offer significantly improved signal efficiency for next generation networks where bandwidth demands and functionality have outgrown their cable counterparts.

Unprecedented freedom and density

Active Electrical Cables provide significant improvements over both Active Optical Cables (AOCs) and Direct Attach Copper (DAC) cables.

AECs provide more design freedom with advanced functions and improve airflow and thermal heat by taking up to less volume than our DAC solutions. They provide significant cost and power savings over AOCs which expand port densities on shorter data center runs.

AECs expand your reach in the data center

AECs deliver superior signal integrity at distances above 2.5 meters over their DAC counterparts. High performance re-timers, gearboxes and FEC circuitry ensure reliable reaches of up to 7 meters, enabling network redundancy and security.


Breakout your 400G AEC cabling for seamless NIC-TO-TOR connectivity

Unlike 400G DAC and AOC solutions, Approved AECs support 400G to 4x100G breakouts, providing an affordable and efficient connection between 400G switches and servers/NICs.

DAC vs AEC breakout

Fully tested and compliant

Approved’s AECs are in-system tested in Arista, Cisco, Juniper, Broadcom, Intel and Mellanox platforms, and are fully compliant with their respective OSFP, QSFP-DD and QSFP28 MSAs.
