Applications

Built for InfiniBand NDR fabrics, GPU clusters and AI training networks, this Twin-port OSFP IHS/Closed Finned Top module carries 850Gbps (8x 106.25Gbps) over SMF up to 500m per link. 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

Standards and Compatibility

Standards compliance covers OSFP MSA, CMIS Rev 5.2, IEEE 802.3cu, IEEE 802.3ck. The unit works in any equipment with a standard Twin-port OSFP IHS/Closed Finned Top interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Ordering Information

Our part number for this module is OSFP-2FR4L-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.

Worldwide Delivery

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.

Quality Assurance

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Package

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.

Built to Your Spec

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
