January 29, 2026, Shenzhen, China. – Driven by design innovation, GIGALIGHT officially announces the launch of its 800G OSFP HYBRID ACC+ active copper cable interconnect solution. Unlike conventional 800G AEC designs, the HYBRID ACC+ adopts a semi-DSP architecture, significantly reducing overall power consumption and system cost while maintaining high-speed signal integrity.

GIGALIGHT’s Open Laboratory conducted comprehensive debugging and validation using an in-house developed checker instrument, followed by interoperability testing on NVIDIA 800G InfiniBand switches. The results demonstrate that the 800G OSFP HYBRID ACC+ 5-meter active copper cable is fully compatible with 800G switching systems, delivering excellent signal performance:

• Pre-FEC BER at the 1E-9 level
• Post-FEC BER reaching 1E-15 or better
• Eye Opening Info FOM values above 70 for the majority of channels

These results confirm the robust signal quality and system stability of the HYBRID ACC+ solution.

Positioned against mainstream industry AEC active copper cables, the HYBRID copper interconnect extends the maximum reach of 800G active copper links to beyond 5 meters. By deploying DSP capability on only one side—either the line side or the host side—for high-speed signal compensation and processing, the HYBRID architecture reduces the required number of DSP channels (or chips) by approximately 50% compared with conventional AEC solutions. As a result, the product achieves a typical power consumption of around 5.5W per end, with an end-to-end latency of approximately 100 ns at 5 meters. Under equivalent reach conditions, overall power consumption, latency, and system cost can be improved by about 40%.

In parallel, GIGALIGHT has also initiated the development of HYBRID 1.6T ACC active copper cable products to address next-generation ultra-high-speed interconnect requirements.
