Applications

The NVIDIA InfiniBand Compatible 800G OSFP224 DR4 FL Optical Transceiver is used in InfiniBand NDR fabrics, GPU clusters and AI training networks, where it provides an 850Gbps (4x 212.5Gbps) link over SMF up to 500m. 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 InfiniBand hardware, it is a drop-in equivalent of the MMS4A20-XM800.

Standards and Compatibility

Compliance: OSFP MSA, CMIS Rev 5.2, IEEE 802.3dj, OIF 224G-VSR. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMS4A20-XM800 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

Our part number for this module is OSFP224-DR4-800G-FL. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

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.

How We Pack

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

Custom-made Fiber Products

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.

Shipping and Lead Time

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
