800G OSFP 2x FR4 Optical Transceiver

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.

In InfiniBand NDR fabrics, GPU clusters and AI training networks, the 800G OSFP 2x FR4 Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over SMF with a reach of 2km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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.

Our part number for this module is OSFP-2FR4-800G. 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.

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.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

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.
