Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this QSFP112 module carries 425Gbps (4x106.25Gb/s) over MMF up to 30m@OM3/50m@OM4 per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with NVIDIA/Mellanox InfiniBand systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMA1Z00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

This product is designed and tested to comply with QSFP112 MSA, CMIS Rev5.0, IEEEdf-2024. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MMA1Z00-NS400.

To order, quote QSFP112-SR4-400G 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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
