400G OSFP56 CABLE

Lightx’s 400G OSFP56 Transceiver-Cable is a high-density, integrated solution engineered for ultra-short-reach connectivity in hyperscale data centers, AI/ML clusters, and high-performance computing (HPC) environments. Combining an OSFP56 transceiver with a fixed-length passive copper (DAC) or active optical cable (AOC), it delivers 400Gbps full-duplex bandwidth using 8x50G PAM4 modulation. Designed for top-of-rack (ToR) and within-rack interconnects, it eliminates standalone optics, reducing power consumption, latency, and deployment complexity. The OSFP56 form factor ensures backward compatibility with OSFP and QSFP-DD ports via adapters, while supporting flexible breakout configurations (e.g., 2x200G or 4x100G) for seamless integration into legacy infrastructure. Enhanced thermal management and a robust mechanical design ensure reliable operation in high-density, high-temperature deployments. Ideal for GPU/CPU clusters, storage networks, and cloud-edge applications, it offers plug-and-play simplicity, cost efficiency, and scalability for future 800G/1.6T upgrades.
