The 800G OSFP 2x FR4 Optical Transceiver is a Twin-port OSFP IHS/Closed Finned Top optical transceiver delivering 850Gbps (8x 106.25Gbps) over SMF. Operating at 1271nm, 1291nm, 1311nm and 1331nm with a Dual Duplex LC/UPC interface, it reaches 2km and is compliant with OSFP MSA HW Rev 4.1, CMIS Rev 5.0, IEEE 802.3cu-2021, IEEE P802.3ck D2.2. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in InfiniBand NDR fabrics, GPU clusters and AI training networks.

The 800G OSFP 2x FR4 Optical Transceiver is used in InfiniBand NDR fabrics, GPU clusters and AI training networks, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 2km. The Dual Duplex LC/UPC interface and 1271nm, 1291nm, 1311nm and 1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with NVIDIA/Mellanox InfiniBand systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMS4X50-NM. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA HW Rev 4.1, CMIS Rev 5.0, IEEE 802.3cu-2021, IEEE P802.3ck D2.2. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMS4X50-NM 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.

Order this product as OSFP-2FR4-800G. 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.

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.

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.

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.

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.
