800G QSFP Q112 AEC Cable

Ascent's 800G QSFP-DD to QSFP-DD Active Electrical Cable (AEC) is a high-performance, low-latency copper interconnect solution designed for next-generation AI infrastructure, cloud data centers, high-performance computing (HPC), and hyperscale Ethernet networks. The cable integrates advanced DSP retimer technology to extend copper transmission distance while maintaining excellent signal integrity, enabling reliable 800Gb/s connectivity between servers, switches, storage systems, and GPU clusters. The AEC features QSFP-DD connectors on both ends and supports an aggregate data rate of 800Gb/s (8 × 106.25Gb/s PAM4) over a single cable assembly. Integrated signal conditioning and retiming technology compensate for channel loss, improve eye margin, and ensure robust transmission performance over longer copper links compared with passive DAC solutions. Operating from a 3.3V power supply, the cable supports hot-pluggable operation and provides comprehensive diagnostics, including PRBS generation and checking, loopback testing, signal-to-noise ratio (SNR) monitoring, eye histogram analysis, and advanced performance monitoring for simplified deployment and maintenance. Designed in accordance with the QSFP-DD MSA and CMIS 5.0 specifications, the Ascent 800G AEC delivers a compact, energy-efficient, and cost-effective interconnect solution for high-density networking environments. The cable supports 800G Ethernet applications and is backward compatible with 400G and 200G operating modes, making it an ideal choice for AI clusters, Ethernet switches, storage networks, and next-generation data center architectures requiring reliable medium-reach electrical interconnects.
