Applications
The 800G OSFP 2x LR4L 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 6km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 8x 100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, CMIS v5.1/v5.2, IEEE 802.3cu and 802.3ck. It plugs into any standards-based Twin-port OSFP IHS/Closed Finned Top port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
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.
Packaging
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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
Quality and Testing
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.
