Applications

The 400G OSFP SR4 FL Optical Transceiver is used in InfiniBand HDR fabrics, HPC clusters and AI computing networks, where it provides a 425Gbps (4x106.25Gbps) link over MMF up to 30m@OM3/50m@OM4 or OM5. With its MPO-12/APC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MMA4Z00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards and Compatibility

This product is designed and tested to comply with 400G InfiniBand NDR, OSFP MSA Rev 5.0、IEEE 802.3ck、IEEE 802.3-2022. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MMA4Z00-NS400.

Ordering Information

Order this product as OSFP-SR4-400G-FL. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

Packing Details

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

Custom-made Fiber Products

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.

Delivery

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.

Quality Assurance

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.
