400G QSFP112 CABLE

Lightx’s 400G QSFP112 transceiver-cable is an integrated, high-speed solution for ultra-short-reach interconnects in hyperscale data centers, AI/ML clusters, and high-performance computing (HPC) environments. Combining a QSFP112 transceiver with a fixed-length passive copper (DAC) or active optical cable (AOC), it delivers 400Gbps full-duplex bandwidth using 4x112G PAM4 modulation. Designed for within-rack and top-of-rack (ToR) connectivity, it eliminates the need for separate optics, reducing power consumption, latency, and deployment complexity. The QSFP112 form factor ensures backward compatibility with QSFP-DD and QSFP28 ports via adapters, while supporting breakout configurations (e.g., 4x100G or 2x200G) for flexible integration into legacy infrastructure. With robust thermal management and plug-and-play simplicity, it optimizes cost efficiency and port density in space-constrained, high-temperature environments. Ideal for GPU/CPU clusters, storage networks, and cloud-edge deployments, it future-proofs infrastructure for scalable upgrades to 800G/1.6T architectures.
