Applications
Network architects choose the 800G OSFP 2x FR4L Optical Transceiver for InfiniBand NDR fabrics, GPU clusters and AI training networks: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 500m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. 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 Rev 5.2, IEEE 802.3cu, IEEE 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
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
