400G QSFP-DD Active Optical Cable with DDM (1-100m): 400G-AOC-QSFP-DD

The EDGE 400G-AOC-QSFP-DD is a 400G QSFP-DD active optical cable built in a point-to-point configuration, with QSFP-DD connectors on both ends and the fiber optics embedded directly in the cable assembly. Reach extends up to 100 meters, which suits data center interconnects, inter-row links, and AI or HPC cluster backbones that need more distance than passive copper cabling can cover in the same rack rows.

Data rate spans 212.5 to 425 Gbps. On Ethernet, the cable covers 200G Ethernet at 212.5 Gbps and 400G Ethernet at 425 Gbps for spine-leaf and leaf-to-server links in cloud and hyperscale data centers. On InfiniBand, it covers EDR at 100 Gbps and HDR at 200 Gbps, which fits high-performance computing clusters and GPU-accelerated training infrastructure that depend on interconnect bandwidth.

The cable uses an 850 nm VCSEL transmitter and a PIN photodiode receiver, with parallel multimode fiber pairs terminated inside the assembly. The embedded multimode fiber runs OM3 up to 70 meters and OM4 up to 100 meters, so the achievable reach depends on the fiber grade already installed in the plant. Because the fibers are permanently terminated inside the cable assembly, there are no exposed connectors to clean, inspect, or protect during installation, which simplifies deployment compared with separate transceivers and patch cords.

Host-based Forward Error Correction is supported for signal integrity at these rates. Being an active optical cable, it carries the electromagnetic interference immunity inherent to fiber transmission, which matters in dense GPU and switch racks with heavy electrical noise. The cable is also lighter and more flexible than an equivalent copper DAC of the same reach class, which eases routing and improves airflow in tightly packed racks.

Electrically, the cable runs from a +3.3V single power supply with a maximum power draw of 8W and follows the QSFP-DD MSA and CMIS V4.0 interface specifications, so it plugs into standard QSFP-DD host cages without special handling. DDM/DOM diagnostics report real-time optical and operating parameters for link health monitoring after installation.

Compliance covers IEEE 802.3cd, the QSFP-DD MSA, and the InfiniBand EDR and HDR specifications, alongside CE and RoHS. Operating temperature is rated 0 to 70C, with an MTBF of 1,000,000 hours.
