Cisco Compatible Broadcom DSP & Broadcom VCSEL 400GBASE-VR4 QSFP112 PAM4 850nm 50m MTP/MPO-12 APC MMF Optical Transceiver Module
NADDOD Cisco Q112-400G-VR4 Compatible optical transceiver is a 400Gb/s single-port QSFP112 VR4 multimode optical transceiver designed for short-reach 400G Ethernet applications. It features a 4-channel parallel architecture with 100G-PAM4 modulation per lane, uses a single MPO-12/APC optical connector, and supports transmission distances of up to 50 meters over OM4 multimode fiber. The module is compliant with QSFP112 MSA, IEEE 802.3db, and CMIS 4.0 standards, ensuring broad interoperability in modern data center environments.
The 400G QSFP112 VR4 is typically deployed with NVIDIA BlueField-3 DPUs or ConnectX-7 QSFP112 NICs, and can interconnect with dual-port 800G (2×400G) OSFP transceivers. This flexibility makes it an ideal solution for AI Data Centers (AIDC) and high-density Data Center Networks (DCN).
This architecture is built upon the 400G QSFP112 switch to enable high-bandwidth and low-latency data transmission, catering to the needs of high-performance computing (HPC), artificial intelligence/machine learning (AI/ML), big data analysis, and other data-intensive applications.
