The 800G OSFP 2x LR4L Optical Transceiver is a Twin-port OSFP IHS/Closed Finned Top optical transceiver delivering 850Gbps (8x 106.25Gbps) over SMF. Operating at 1270nm, 1290nm, 1310nm, 1330nm with a Dual Duplex LC/UPC interface, it reaches 6km and is compliant with OSFP MSA, CMIS v5.1/v5.2, IEEE 802.3cu and 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.

Applications
Network architects choose the 800G OSFP 2x LR4L Optical Transceiver for InfiniBand NDR fabrics, GPU clusters and AI training networks: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 6km. With its Dual Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.
Standards and Compatibility
Standards compliance covers OSFP MSA, CMIS v5.1/v5.2, IEEE 802.3cu and 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-2LR4L-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.
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
Logistics
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.
Our Testing Process
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.
