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.

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.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.

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.

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.
