In 400G Ethernet data center and cloud network environments, the 400G OSFP DR4L FL Optical Transceiver delivers 425Gbps (4x106.25Gbps) transmission over SMF with a reach of 100m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with NVIDIA/Mellanox Ethernet systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMS4X00-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 OSFP MSA Rev. 5.0, CMIS Rev. 4.0, IEEE Std 802.3bs-2017, IEEE Std 802.3ck-2022. It is interoperable with NVIDIA/Mellanox Ethernet equipment and serves as a direct equivalent to the NVIDIA/Mellanox Ethernet part number MMS4X00-NS400.

To order, quote OSFP-DR4L-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.

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.

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.

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.

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.
