Applications
Network architects choose the 400G OSFP SR4 FL Optical Transceiver for InfiniBand HDR fabrics, HPC clusters and AI computing networks: it runs 425Gbps (4x106.25Gbps) over MMF and reaches 30m@OM3/50m@OM4 or OM5. The MPO-12/APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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 MMA4Z00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MMA4Z00-NS400 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers 400G InfiniBand NDR, OSFP MSA Rev 5.0、IEEE 802.3ck、IEEE 802.3-2022.
Ordering Information
To order, quote OSFP-SR4-400G-FL 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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
