Arista Compatible 400GBASE-DR4 QSFP112 PAM4 1310nm 500m MTP/MPO-12 APC SMF Optical Transceiver Module
NADDOD Arista Q112-400G-DR4 Compatible optical transceiver is a QSFP112-based 400G optical module designed for 400G Ethernet applications. It uses an MTP/MPO-12 connector and supports transmission distances of up to 500 meters over parallel single-mode fiber (PSM). The module is compliant with QSFP112 MSA, CMIS 5.0, and 400GAUI-4 standards, ensuring interoperability across QSFP112 platforms. Integrated digital diagnostic monitoring (DDM) provides real-time visibility into key operating parameters.
The 400G QSFP112 DR4 is typically used with a 400G and 200Gb/s BlueField-3/QSFP112 data processing unit (DPU) or ConnectX-7/QSFP112 based PCIe bus network card, connected to one of the ports of a dual-port 800Gb/s 2x400G OSFP port transceiver, making it ideal for AI Data Center (AIDC) and Data Center Network (DCN) deployments.
This solution combines the powerful processing capabilities of the 800G OSFP switch with the 400G CX7 network card. It utilizes NADDOD optical modules to enable efficient data exchange between devices. Additionally, scalability and flexibility of the network are taken into full consideration to meet the communication demands of future intensive computing requirements.
