Built for 400G Ethernet data center and cloud network environments, this Single-port OSFP RHS/Flat Top module carries 425Gbps (4x106.25Gbps) over SMF up to 100m per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on NVIDIA/Mellanox Ethernet hardware, it is a drop-in equivalent of the MMS4X00-NS400.

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.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

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.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
