In 400G Ethernet data center and cloud network environments, the NVIDIA InfiniBand Compatible 400G QSFP112 DR4 Optical Transceiver delivers 425Gbps (4x106.25Gb/s) transmission over SMF with a reach of 500m. The MPO-12/APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

This product is designed and tested to comply with QSFP112 MSA, CMIS 5.0, IEEE Std 802.3ck. It plugs into any standards-based QSFP112 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

To order, quote QSFP112-DR4-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
