400G QSFP112

Lightx’s 400G QSFP112 transceiver is a high-density, next-generation module tailored for 400 Gigabit Ethernet and AI/cloud infrastructure. Built on the compact QSFP112 form factor, it employs 4x112G PAM4 modulation to deliver 400Gbps aggregate bandwidth, optimized for hyperscale data centers and high-performance computing (HPC) environments. Advanced DSP and low-power silicon photonics ensure robust signal integrity and thermal efficiency for short-reach (SR) and extended-reach (ER) interconnects. Backward-compatible with QSFP56 and QSFP28 ecosystems via breakout configurations, it enables cost-effective upgrades while supporting seamless integration into existing network architectures. Designed for scalability, it paves the way for future 800G/1.6T deployments, combining ultra-low latency with high port density for AI/ML workloads and cloud-native applications.
