As AI model training exceeds trillions of parameters, the interconnect communication bandwidth and transmission distance requirements between GPUs, CPUs, and other peripherals are growing exponentially. Traditional data interconnect methods are no longer able to keep up with the current pace of AI cluster upgrades, necessitating the search for more efficient, lossless, reliable, and long-distance connectivity solutions. Against this backdrop, "PCIe over Optics" technology has emerged to support the expansion and upgrade of AI clusters, such as rack-scale computing architectures.


SONT rapidly launched its PCIe 5.0 QSFP-DD AOC product, which recently passed testing and verification by a Tier 1 equipment vendor, demonstrating excellent performance:

Ultra-Low Power Consumption

Power consumption per port is less than 4W (typically 3.5W), enabling customers to deploy ultra-low power systems.

High Performance

Bidirectional, 8-channel, high-bandwidth transmission achieves a bit error rate of less than 1E-12 over extended testing periods, achieving zero system-level bit errors and providing customers with lossless, reliable interconnect links.
Long-distance:

Enables inter-cabinet and inter-server connectivity over distances ranging from tens to hundreds of meters. This significantly increases the connection distance by tens to hundreds of times compared to the 1.4-meter distance of traditional PCIe connections, supporting flexible deployment.

Hot-swappable:

Utilizing the standard QSFP-DD form factor, it supports hot swapping, meeting customer needs for rapid deployment and iteration.

 

From September 10th to 12th, 2025, SONT will showcase its new products at the China International Optoelectronics Exposition in Shenzhen. We sincerely invite customers worldwide to visit booth #12B35 for more information.
