Applications
The 400G OSFP DR4L FL Optical Transceiver is used in 400G Ethernet data center and cloud network environments, where it provides a 425Gbps (4x106.25Gbps) link over SMF up to 100m. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on NVIDIA/Mellanox Ethernet hardware, it is a drop-in equivalent of the MMS4X00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OSFP MSA Rev. 5.0, CMIS Rev. 4.0, IEEE Std 802.3bs-2017, IEEE Std 802.3ck-2022. For projects standardized on NVIDIA/Mellanox Ethernet hardware, this product replaces the MMS4X00-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
Order this product as OSFP-DR4L-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.
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.
Packaging
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.
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
