200G QSFP56

Lightx’s 200G QSFP56 transceiver is a compact, high-efficiency module designed for 200 Gigabit Ethernet and next-gen data center interconnects. Leveraging 4x50G PAM4 modulation, it delivers 200Gbps aggregate bandwidth in the industry-standard QSFP56 form factor, ideal for high-density switches and routers. Optimized for short-reach (SR) and extended-reach (ER) applications, it integrates advanced DSP and low-power silicon photonics to ensure robust signal integrity and thermal performance. Backward-compatible with QSFP28 ports, it supports breakout configurations (e.g., 4x50G or 2x100G) for seamless integration into legacy infrastructure while enabling cost-effective upgrades. Tailored for 5G transport, enterprise core networks, and cloud edge deployments, it balances ultra-low latency, scalability, and energy efficiency for AI-driven and storage-centric workloads.
