Description
Description:
The QSFP112 400G PAM4 optical transceiver is a high-speed, single-port module designed for multimode fiber (MMF) short-reach applications. It supports 4×100Gb/s PAM4 lanes with an MPO-12 connector, delivering reliable 400Gb/s connectivity over distances up to 50–100 meters on OM4 fibers. Optimized for low latency, low power, and high reliability, it seamlessly integrates into modern data centers, spine-leaf networks, and high-performance computing (HPC) environments.
Features:
Ready for 800G Evolution
The 400G QSFP112 SR4 optical module is based on a streamlined 4x100G PAM4 electrical lane design. Simply replace the module to scale up to an 800G solution (8x100G PAM4—2xQ112), enabling seamless evolution to higher bandwidth.
Flexible Multi-Device Connectivity
Supports a variety of device interconnections. Easily pairs with QSFP112/QDD switches and server adapters like ConnectX-7 and BlueField-3, allowing seamless configuration across different architectures while minimizing compatibility issues and investment risk.
