400G QSFP-DD Active Optical Cable

This series of active optical cables adopts innovative optoelectronic integration technology, suitable for 400GbE ultra-high-speed transmission scenarios, and realizes lossless signal transmission through OM4 multimode optical fiber. Its breakthrough architecture features include:

Eight-channel parallel transmission system
Each end is equipped with an eight-channel multimode optical fiber transceiver module, with a single-channel transmission rate of 53Gbps, and a breakthrough performance of 400Gbps total bandwidth is achieved through PAM4 modulation technology. The module has a built-in intelligent signal

compensation mechanism to ensure long-distance transmission stability.

Full protocol compatible design
Strictly follow international mainstream technical standards:

•IEEE 802.3cd 400G Ethernet protocol

•OIF-CEI-04.0 optoelectronic interface specification

•QSFP-DD MSA hardware packaging standard

•CMIS Rev4.0 manageable interface protocol
Perfectly adapt to mainstream manufacturers' switching equipment, support hot plugging and real-time status monitoring.

High-density deployment advantages
The ultra-thin wire design (outer diameter <4.2mm) with a 30% reduction in wire diameter, combined with flexible sheath materials, achieves a wiring density of up to 576 ports in a 1U space. The revolutionary air guide structure design improves heat dissipation efficiency by 40% compared to traditional copper cables, and is particularly suitable for high-heat density scenarios such as GPU clusters.

Enterprise-level reliability guarantee
Passed 100,000 plug-in and pull-out test certification, supporting 7x24 hours of uninterrupted operation. Using military-grade fiber optic connectors, the bit error rate is less than 1E-15, the MTBF exceeds 500,000 hours, and a five-year warranty is provided.
