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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MMA4Z00-NS400.
Standards and Compatibility
Compliance: 400G InfiniBand NDR, OSFP MSA Rev 5.0、IEEE 802.3ck、IEEE 802.3-2022. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMA4Z00-NS400 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
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.
Built to Your Spec
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.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
