800G OSFP 2x FR4L Optical Transceiver

The 800G OSFP 2x FR4L 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 500m and is compliant with OSFP MSA, CMIS Rev 5.2, IEEE 802.3cu, IEEE 802.3ck. 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 FR4L Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over SMF with a reach of 500m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 8x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

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.

Order this product as OSFP-2FR4L-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.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
